Adaptability and Stability of Irrigated Barley Genotypes in the Cerrado of the Federal District

Barley (Hordeum vulgare L.) is a significant cereal globally, widely used in human and animal food. Furthermore, it has a strong influence on genotype-by-environment interactions, being considered a highly adaptable crop. This study aimed to estimate the parameters of adaptability and stability for 17 barley genotypes, compared with two controls (BRS 180 and BRS 195) grown under irrigation in the Cerrado. The experiments were conducted from 2017 to 2020, from May to September, in two different experimental areas of Embrapa in the Federal District, Brazil. Five traits were evaluated: 1. Esti mated grain yield (kg ha−1); 2. CL1—commercial classification of first grains (>2.5 mm) (%); 3. TGW—1000-grain weight (g); 4. plant height (cm); 5. cycle—days after emergence to earing (days). The data obtained were analyzed for normality and homogeneity of variance, subjected to individual and joint analysis of variance, with means compared by Tukey’s test at 5% significance and the adaptability and stability parameters estimated for the genotypes. The coefficients of environmental variation (CV%) were generally low, indicating good experimental precision. The PFC 2006053 and PFC 2006054 genotypes have broad adaptability and high stability for most traits and outperformed the controls and the overall experiment average.

Screening and Site Adaptability Evaluation of Qi-Nan Clones (Aquilaria sinensis) in Southern China

In recent years, plantations of Aquilaria sinensis in China have been dominated by Qi-nan, yet there remains limited research on the growth evaluation and breeding of these clones. In this study, a multi-point joint variance analysis, an additive main effect and multiplicative interaction (AMMI) model, a weighted average of absolute scores (WAASB) stability index, and a genotype main effect plus a genotype-by-environment interaction (GGE) biplot were used to comprehensively analyze the yield, stability, and suitable environment of 25 3-year-old Qi-Nan clones from five sites in southern China. The results showed that all the growth traits exhibited significant differences in the clones, test sites, and interactions between the clones and test sites. The phenotypic variation coefficient (PCV) and genetic variation coefficient (GCV) of the clones’ growth traits at the different sites ranged from 16.56% to 32.09% and 5.24% to 27.06%, respectively, showing moderate variation. The medium–high repeatability (R) of tree height and ground diameter ranged from 0.50 to 0.96 and 0.69 to 0.98, respectively. Among the clones, Clones G04, G05, G10, G11 and G13 showed good growth performance and could be good candidates for breeding. Environmental effects were found to be the primary source of variation, with temperature and light primarily affecting growth, while rainfall influenced survival and preservation rates. Yangjiang (YJ) was found to be the most suitable experimental site for screening high-yield and stable clones across the different sites, whereas the tree height and ground diameter at the Chengmai (CM) site were significantly higher than at the other sites, and the Pingxiang (PX) and Zhangzhou (ZZ) sites showed poor growth performance. The findings suggest that Qi-nan clones are suitable for planting in southern China. There were also abundant genetic variations in germplasm resources for the Qi-nan clones. The five selected clones could be suitable for extensive planting. Therefore, large-scale testing is necessary for determining genetic improvements in Qi-nan clones, which will be conducive to the precise localization of their promotion areas.

CRUDE PROTEIN CONTENT IN PIGEON PEA GRAIN LINES

Pigeon pea (Cajanus cajan (L.) Millspaugh) is a multipurpose legume, which can be used as a grain producer, fodder and soil improver. Its nutritional composition has high protein, on average 22%, characterizing a relevant species in several emerging countries. Although it is an important crop in semi-arid regions of other countries, in Brazil has been little used and studied, so that it is still considered a subsistence culture. The goal of the present study was to evaluate the protein content in 21 lines of pigeon pea, from the breeding program of Embrapa Semiárido, including the control variety ‘guandu Petrolina’. The experiments were conducted in Barbalha/CE, Petrolina/PE and Juazeiro/BA, years of 2019, 2020 and 2021, distributed in four environments, three under irrigated cultivation and one under rainfed cultivation. The experiments were arranged in plots with two planting lines measuring 2.4m x 2.5m, spaced between rows by 1.2m and between plants by 0.5m, with two plants per hole, using a randomized block design with three replications. The cultural treatments consisted of manual weeding, without any type of fertilization in the experimental area. The determination of total nitrogen and crude protein was performed using the Kjeldahl method. The genotype × environment interaction was highly significant (p<0.01) for protein content. There was no significant difference between the levels of protein under irrigated and rainfed cultivation. After joint analysis of variance among the four environments, the control cultivar 'Petrolina presented the highest average, with 24.60%. The lowest protein average was presented by treatment 17 (ICPL 900053 x Anagé), 20.12%. Lines 12 (ICPL 90053 x D2 Type), 9 (ICPL 90045 x ICPL 89027) and 19 (ICPL 89027 x D3 Type) expressed acceptable values for protein content, 22.35, 21.99 and 22.72%, respectively, associated with high productivity, broad adaptability and good predictability, showing great potential to be new cultivars to the Brazilian semiarid region.

Reação de linhagens de milho à estria bacteriana

Abstract The objective of this work was to select experimental corn lines genetically resistant to the bacterial leaf streak caused by Xanthomonas vasicola pv. vasculorum, in two growing seasons. The treatments were carried out in an experimental randomized block design in the 2019/2020 and 2020/2021 growing seasons, under a covered environment, with open ventilation, with four replicates. Seven lines resistant to and seven susceptible to foliar diseases were evaluated, in addition to two commercial hybrids used as checks. At the corn flowering stage, an artificial inoculation containing 3.78x1010 CFU mL−1 of bacterial suspension was performed, and disease incidence and severity were assessed, based on a diagrammatic scale, every seven days. From these evaluations, the areas under the disease progress curve for each line were calculated, and individual and joint analyses of variance were performed. There is genetic variability among the corn genotypes for reaction to bacterial leaf streak, with a significant effect for the areas under the disease progress curve for incidence (AUDPCI) and severity (AUDPCS) between genotypes and between growing seasons, and for the genotype x season interaction. Lines LV1 and L14 are possible source genotypes for genetic resistance to the bacterial leaf streak.

Adaptabilidade e estabilidade da produtividade de grãos e de caracteres de pendão de milho

ABSTRACT: Due to the economic importance of maize, it is essential to evaluate the performance of genotypes under environmental variations (years, locations, and seasons). Consequently, researchers have scrutinized genotype-environment (G×E) interactions to ensure reliability in genotype recommendations. Furthermore, when a G×E interaction exists, adaptability and stability analysis can be performed. This analysis enables one to identify genotypes with predictable responses and adaptability to environmental variability. Hence, this study sought to determine if there is a G×E interaction and evaluate the response of 16 maize genotypes across seven environments through adaptability and stability analyses. Seven experiments were conducted with 16 maize genotypes using a randomized complete block design with three replications. Tassel length (TL), tassel branch number (TBN), tassel dry matter (TDM), and grain yield (GY) were evaluated. Individual and joint variance analyses were performed, along with the F-test at a 5% significance level. The complex parts of the interaction between genotypes and pairs of environments were estimated, followed by adaptability and stability analyses using the Eberhart and Russell method. A genotype-environment interaction was found for TL, TBN, TDM, and GY, indicating that genotypes respond differently in various environments. However, considering all four traits, there is no indication of the ideal genotype.

Methodologies to determine the ripening stage of coffee fruits

The asynchronous flowering of coffee trees results in uneven ripening, which makes harvesting ripe fruit crops difficult. To determine the ideal time for harvesting, representative sampling is required. However, existing sampling processes are labor-intensive. Therefore, this study aimed to determine the optimal number of plants and most efficient methodology to evaluate coffee fruit ripening. The experiment was conducted in Inconfidentes, state of Minas Gerais, with trials carried out on Catuaí Vermelho and Icatu Vermelho cultivars. The results of the fruit quantities were subjected to analysis of variance. An individual statistical analysis was performed and, if the homogeneity of residual variances was lower than seven, a joint analysis of variance was performed on the two crops. Each experiment had four treatments and six repetitions. We then performed a joint analysis of the data and used simulation to determine the optimal number of plants to be evaluated. The interaction between treatments and cultivars showed a significant difference in the green and cherry stages, but not in unripe, ripe, and dry fruits, and the optimal number of plants to sample varied by cultivar and treatment. It was found that the optimal number of plants to sample is 13 for the Icatu cultivar and 14 for the Catuaí cultivar using the central rosette harvesting treatment

Correlações canônicas em caracteres fenológicos, morfológicos, produtivos e de pendão de milho

ABSTRACT The objective of this study was to check whether there is linear dependence between phenological, morphological and production traits and tassel traits in maize genotypes. Seven experiments were conducted with 16 maize genotypes, in a randomized block design, with three replicates. Four groups of traits were evaluated: phenological (two), morphological (three), production (four) and tassel (11). Joint analysis of variance and F test at 5% significance level were performed. The matrix of phenotypic correlation coefficients between the traits was estimated and multicollinearity was diagnosed in each group of traits. Associations between the groups of traits were checked by canonical correlation analysis. There is linear dependence between phenological, morphological and production traits and tassel traits in maize genotypes. Phenological (number of days from sowing to 50% of male flowering and number of days from sowing to 50% of female flowering), morphological (plant height and spike height) and production (number of spikes and grain yield) traits are positively associated with tassel traits (tassel branch number and tassel dry matter). Tassel branch number and tassel dry matter can be used for indirect selection of maize plants.

Parâmetros genéticos em subacessos de melão da agricultura tradicional

ABSTRACT Family farming in Brazil holds a high diversity of melon germplasm, composing an important source of alleles for breeding programs. Thus, the objective of this study was to estimate genetic parameters and select genotypes from a population of melon sub-accessions from different botanical varieties grown by family farmers, based on morphological parameters. Two experiments were conducted, one in 2019 and another in 2020, in a complete randomized block design, with three replications and five plants per plot, using 27 melon sub-accessions (generation S2) from family farmers, and a commercial variety. Nine quantitative descriptors were evaluated. Assumptions of ANOVA were tested, followed by individual and joint analyses of variance. Significant differences were found among sub-accessions for all descriptors evaluated, with heritabilities higher than 83% and significant genotype-environment interactions for 88.8% of the characteristics evaluated. Thus, genetic variability was found among sub-accessions, with predominance of genetic effects over environmental effects, denoting the possibility to obtain genetic gains by the improvement of several characteristics of agronomic interest. The sub-accessions BGMEL66.0, BGMEL111.0, and BGMEL112.0 are recommended for inclusion in breeding programs focused on obtaining good prolificacy and small fruits with high soluble solid contents. BGMEL sub-accessions (108.3 and 108.5) can generate progenies with high prolificacy, and sub-accessions of the variety momordica can be used for generation of progenies focused on shortening the crop cycle and increasing fruit size.

Tomateiro cereja ornamental em diferentes ambientes protegidos e materiais refletores em bancada de cultivo

ABSTRACT The study aimed to evaluate the growth of ornamental cherry tomato plants in different protected environments and reflective materials on the cultivation benches. As there were no repetitions of the protected environments, each environment was considered an experiment. In each environment, the experimental design used was completely randomized with five replications and three plants per plot. From the analysis of individual variances and evaluation of the mean squares of residues smaller than seven, the joint analysis of variance was performed (three protected environments x three reflective materials on the cultivation bench + 1 control without material). The protected environments evaluated were the agricultural greenhouse with a screen of 42-50% shading under the film, the agricultural screenhouse with a black screen of 30% shading, and the agricultural screenhouse with an aluminized screen of 35% shading. The reflective materials on the cultivation bench were Aluminet®, white Formica laminate, and red Formica laminate. The different protected environments influenced the growth of plants, and due to the lower incident light, the plants showed greater height in the agricultural greenhouse (42-50% shading). The reflective benches did not interfere with plant height but favored fruit production. The agricultural greenhouse (42-50% shading)) stands among the environments. For the reflective materials on the bench, aluminized fabric and red Formica laminate stood out, as they favored the growth of cherry tomato plants with desirable ornamental traits, such as greater fruit production.

Adaptability and stability of corn hybrids for silage via genotype and genotype × environment interaction biplot

AbstractThe occurrence of the genotype × environment (G × E) interaction is one of the main factors that hinder the selection of adapted and stable genotypes. The genotype and G × E interaction (GGE) biplot methodology is an efficient process to detect corn (Zea mays L.) hybrids for silage and, consequently, will help in the recommendation of new and more stable hybrids in different environments in breeding programs. In this sense, this study aimed to evaluate and select corn hybrids for silage that simultaneously combine high yield and stability in different environments in the state of Rio de Janeiro, Brazil, via GGE biplot. Eleven corn hybrids, eight precommercial topcrosses and three commercial controls, were evaluated at three sites (Campos dos Goytacazes, Cambuci, and Itaocara, Rio de Janeiro) during two seasons: the 2017–2018 season and 2018–2018 off‐season. The experiments were designed in completely randomized blocks with three replications. Individual and joint analyses of variance were performed and, after detecting significant interaction between genotype and environment, the adaptability and phenotypic stability of corn genotypes for silage were analyzed using the GGE biplot methodology. The GGE biplot analysis was efficient in interpreting the data and represented 83.68% of the total variation in the first two principal components. The use of the GGE biplot method allowed the recommendation of more productive, stable, and responsive hybrids for the state of Rio de Janeiro. The hybrid UENF MS2208 is indicated for cultivation in the state of Rio de Janeiro for combining high green biomass yield and stability.

Análise GGE biplot quanto à adaptabilidade e estabilidade de genótipos de trigo em Moçambique

Abstract The objective of this work was to use the GGE biplot method to select superior wheat genotypes for adaptability and stability, and to determine grain yield in Sussundenga, Bárué, and Lichinga, in Mozambique, in the 2018/2019, 2019/2020, and 2020/2021 crop years. Eleven treatments were evaluated, using ten wheat genotypes from International Maize and Wheat Improvement Center and a control cultivar developed by a Zimbabwean seed company and used in the national wheat program of the country. Grain yield was the main trait evaluated through individual and joint analyses of variance, adaptability, and stability. The effects of genotypes and the genotype × environment interaction were significant. The adaptability and stability analysis using the GGE biplot method showed that the first two main components explained 94.6% of the total variation for year effect, and 91.8%, for the location effect. The following genotypes can be selected for favorable and unfavorable environments: G1, considered ideal due to its high mean yield and stability over the years; and G4 and G7, for simultaneously showing a high yield and stability over the years.

Seleção de genótipos de algodoeiro sob estresse hídrico para produtividade e qualidade de fibra

ABSTRACT The objective of this work was to select a cotton line tolerant to water stress, based on yield and fiber quality characteristics. A total of nine cotton genotypes were evaluated (six breeding lines and three commercial cultivars) in two field experiments conducted in Quixeramobim - CE without water supplementation in 2018 and 2019, respectively. Traits related to cotton lint yield and intrinsic fiber quality were measured. Data were submitted to individual and joint analysis of variance, and selection by the selection index. The genetic variability among the materials demonstrates the possibility of significant gains in the cotton selection process. The genotypes CNPA 2013 - 2235 RF FL, CNPA 2013 - 2064 RF FL and CNPA 2012 - 160 RF FL, as well as the cultivar FM 944 GL, had higher production and better fiber quality under rainfed conditions.

Produtividade, qualidade físico-química e resistência ao florescimento precoce de híbridos experimentais de cebola

ABSTRACT In order to produce bulbs or seeds, onion plants depend on genotype X environment interaction. Thus, breeders shall select the genotypes based on the climatic conditions of each producing region. This study aimed to evaluate 17 experimental onion hybrids and two commercial genotypes (‘Bella Dura’ and ‘Buccaneer’), based on agronomic, physicochemical attributes of the bulbs and resistance to early flowering under subtropical conditions. Joint analysis of variance and phenotypic divergence estimated through principal component analysis (PCA) and Ward’s hierarchical clustering were performed. We observed that the time of transplantation affected the agronomic traits more than the physicochemical traits, not affecting the percentage of early flowering of the genotypes. The first transplant season provided higher bulb productivity, whereas the second season reduced the cycle and productivity. Hybrids H1, H17 and ‘Buccaneer’ showed flowering rate lower than 3%. Among the experimental hybrids, H2 showed higher productivity when comparing with commercial cultivars, and H1, H12 and H14 were equivalent to them. However, H12 showed the highest early flowering rate (43%). Thus, considering the experimental genotypes evaluated under subtropical conditions, H1, H2, and H14, showed potential for commercial use or as potential parents in advancing the breeding program, as they stood out for presenting good yield, bulb quality and low percentage of early flowering.

Vigor assessment of juvenile rubber tree clones in Northwestern São Paulo State, Brazil

Besides rubber production, one of the main goals of the genetic improvement of rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg.] is to develop vigorous clones. The objective of the present study was to evaluate the vigor of 34 elite juvenile rubber clones. To this end, three experiments were conducted in the municipality of Pontes Gestal, in the northwest region of the São Paulo State. Each experiment consisted of 10 treatments, and 2 controls in common to the 3 experiments. The experiments were arranged in the randomized block design, with three replications and ten plants per plot, in the 8 m x 2.5 m spacing. Individual and joint analyses of variance were performed. The means were compared using the Dunnett test at 5%. Significant effect of treatments was found in the three experiments and in the joint analysis. The most vigorous clones were not different from the controls in the comparison of means by the individual and joint analyses. The less vigorous clones were statistically different from the others and from the controls, reflecting this difference in the genetic variability observed. The breeding program must consider the lack of difference between the most vigorous clones and the controls when recombining superior clones, since genetic gain depends on variability.

Adaptability and yield stability of soybean genotypes by mean Eberhart and Russell methods, artificial neural networks and centroid

The soybean crop is prominent in national and international scenarios. A large part of the world production of soybean is cultivated in Brazil and this has been possible due to the performance of different technological areas, among them genetics and plant breeding. Soybean breeding has acted in the development and launch of new cultivars and for this it is required the studies of interaction genotypes x environments and those of adaptability and stability. Thus, the objective was to evaluate the adaptability and phenotypic stability of the grain yield of late-cycle soybean genotypes. Five experiments were conducted in the state of Minas Gerais, each of which was considered as an environment. In each, 17 soybean genotypes were evaluated in a randomized block design with three repetitions, for grain yield, in kg ha-1. The data were analyzed by means of individual (each environment) and joint analysis of variance. Subsequently, analyses of adaptability and phenotypic stability were performed using the methods of Eberhart and Russell (1966), Artificial Neural Networks (Nascimento et al., 2013) and Centroid (Rocha, Muro‑Abad, Araujo, & Cruz, 2005). The results indicated the classification of the analyzed genotypes for unfavorable, general or favorable adaptability, with high or low stability. DM-339 is indicated for favorable environments and UFV-18 (Patos de Minas), UFV91-651226, UFV99-8552093, UFV01-871375B, UFV01-66322813 and UFV99-8552099 are indicated as general adaptability, considering the three methods of adaptability and stability analysis.

Fruit production and quality of sweet orange genotypes selected for the state of Acre, Brazil

The Acre State, Brazil, has edaphoclimatic conditions suitable for the cultivation of sweet orange trees; however, production is limited by the lack of genotypes adapted to the region. The aim of this study was to evaluate the production and quality of sweet orange fruits grafted onto ‘Rangpur’ lime, in order to identify promising genotypes that could be used as a cultivar. The experiment was carried out between 2010 and 2012 in the experimental field of Embrapa, AC, Brazil, in a randomized block design, with 19 genotypes and local Aquiri cultivar. These were propagated by budding, originated from matrices propagated by seeds, and were selected from nine municipalities of Acre, Brazil. A total of 20 treatments with three replications were used in this study. The number of fruits per plant, production per plant, productivity, and fruit quality (fruit mass, longitudinal and transversal fruit diameter, peel thickness, juice yield, soluble solids, titratable acidity, quotient between soluble solids and titratable (ratio), and technological index) were evaluated. Joint analysis of variance and Scott-Knott tests were performed to compare means, as well as Pearson’s correlation and cluster tests, using the Ward method and Mahalanobis distance. The sweet orange genotypes 6, 8, 9, 52, and Aquiri cultivar presented the best productivity indicators, with average values ??above the national productivity. The isolated effect of the year factor showed a greater number of fruits, production per plant, and productivity in the 2010 harvest.

LEAF DIAGNOSIS AND PRODUCTIVITY OF FORAGE SORGHUM FERTIGATED WITH NITROGEN DOSES IN TWO HARVESTS

The aim of the present study was to evaluate the degrees of macronutrients in the diagnostic leaf and the productivity of forage sorghum IPA 467, submitted to fertigation with nitrogen doses, during two harvests (summer and winter), both without regrowth. From January 20 to May 18 and from June 17 and October 14, 2016, two experiments were conducted in Canindé de São Francisco, State of Sergipe, in the Brazilian semi-arid. The experimental design was randomized complete blocks, with four replications. The treatments consisted of four doses of N (0; 80; 160 and 240 kg ha-1). Joint analysis of variance was carried out, considering each different harvest as a new factor. The characteristics evaluated were the content of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) in the leaves, height of the plant, diameter of the stem,green mass productivity, dry mass productivity and percentage of dry mass. The macronutrient content in the leaves was incremented with increasing doses of N, except Ca which presented no influence. The winter crop promoted the highest content of K, while the summer crop presented an elevated absorption of Mg. The varying dosage of N or the harvests season did not influence dry mass productivity (average of 17,386 ton/ha-1). The content of N (23.16-26.68 g kg-1), P (3.16-4.11 g kg-1), K (10.98-33.36 g kg-1), Ca (3.61 g kg-1) and Mg (4.78-9.64 g kg-1) can be considered enough for the full development of the plant.

DROUGHT TOLERANCE IN INTERVARIETAL MAIZE HYBRIDS

ABSTRACT In the period of planting of second-season maize, there is high climatic instability with greater probability of occurrence of water deficit. This is one of the factors that most cause reduction in maize grain yield. In this context, the aim was to identify stable, irrigation-responsive and drought-tolerant maize genotypes. The experiments were conducted in Mococa / SP and Tatuí / SP, at Instituto Agronômico, in two assays, one under full irrigation conditions and the other under water stress. The experimental design was randomized blocks with 3 replicates. Male flowering, female flowering, plant height, ear height, hectoliter weight, one hundred grain weight and grain yield were evaluated. Joint analysis of variance and stability analysis were performed by the GGEBiplot method. Significant genotype and site effects were observed for all traits. Significant effects of genotype x site interaction were found for all traits except ear height and male flowering. The characteristics most affected by water deficit were male flowering, plant and ear heights and grain yield. Genotypes F2 BM709 x PopTol 2, IAC 46 x PopTol 2, F2 30K75 x PopTol 3 and F2 BM709 x PopTol 3 are considered ideotypes because of their high grain yield, phenotypic plasticity and drought tolerance.

Genetic divergence in maize regarding grain yield and tassel traits

Maize tassels with a longer length and higher number of branches prevent the passage of solar radiation into the upper plant canopy and act as a drain for photoassimilates that could be used for grain production. This study aimed to verify if there is genetic divergence regarding grain yield and tassel traits among maize cultivars in three agricultural years. Twenty maize cultivars were evaluated and 11 tassel traits and grain yield were measured. Individual and joint analyses of variance were performed for each trait. Principal component analysis was performed, the generalized Mahalanobis distance matrix between cultivars was determined, and the genetic divergence analysis was performed, using the unweighted pair group method with arithmetic mean (UPGMA), which allowed constructing the dendrogram. The cophenetic correlation coeffi cient was calculated to validate the cluster. There is genetic divergence among maize cultivars and six groups of cultivars were formed. Tassel length, total branches number, central spike dry matter, and grain yield are the traits that most contribute to the genetic divergence among maize cultivars.

Relationship Between Seated Single Arm Shot Put And Isokinetic Shoulder Flexion And Elbow Extension Strength

PURPOSE: Previous studies have demonstrated a strong correlation between isokinetic pushing force and seated single-arm shot-put (SSASP) test performance. However, there is limited research on the contribution of shoulder flexion and elbow extension strength on SSASP test outcomes. Therefore, the purpose of this study was to examine the relationship between isokinetic shoulder flexion and elbow extension strength and SSASP test performance and compare limb symmetry indexes (LSI) between the two tests. METHODS: Healthy, physically active men (n=16, ages=21-34 yrs) and women (n=15, age=18-29 yrs) performed dominant (DOM) and nondominant (NDOM) shoulder flexion and elbow extension isokinetic tests (System 4, Biodex, Shirley, NY) at 60°/s (5 repetitions) and 180°/s (10 repetitions) to determine peak torque production. The average horizontal range from three SSASP (2.0kg ball) trials were computed separately for each limb. In addition to conducting correlational analyses between the peak torques and SSASP distances, the differences in LSI computed between each of the peak torques and SSASP distances were statistically compared at each velocity by joint analysis of variance. RESULTS: Significant (P<.001) relationships were revealed between DOM and NDOM SSASP performance and shoulder (r=.819 to .853) and elbow (r=.803 to .820) peak torques at both velocities. LSI for the SSASP (104.4±7.1%) were similar to the isokinetic LSI at both 60°/s (Elbow: 101.3±10.2%, Shoulder: 102.2±13.8%) and 180°/s (Elbow: 100.4±9.7%, Shoulder: 103.5±12.8%), with no statistically significant differences (P=.364 to .844, η2p=.001 to .028). CONCLUSIONS: Results demonstrate shoulder and elbow isokinetic torques are strongly associated with SSASP distances. Moreover, LSI for both tests were not significantly different from each other, thereby supporting the utilization of the SSASP for making bilateral comparisons in healthy individuals.
