Stability and anatomical parameters of irradiated potato cultivars under drought stress

This study was carried out in Desert Research Center and Faculty of Agriculture, Zagazig University, Egypt, under North Sinai conditions during three growing seasons, i.e., summer 2018, fall 2018/2019 and summer 2019 to assess the effect of radiation mutants on leaf histological features and genetic stability of the productivity of some potato cultivars under drought stress conditions. Results reveal that the genotypes can be statistically classified based on regression coefficient (bi), deviation from regression (S2di) to 4 groups (with low in S2di are considered in all groups) as: (i) Genotype with elevated average, bi = 1, it is considered as stable genotype where Cara cultivar (both generations) was included. (ii) Genotype with elevated average, bi > 1 as genotype with average stability where spunta cultivar was involved. (iii) Genotype with low mean, bi < 1 as genotype with low stability where hermes (both primary (M1) and secondary (M2) radiated generations) and Caruso (2nd generation) cultivars were involved. (iv) Genotypes including a few bi values in one generation, as genotype including low stability but are not recommended for use in this generation where Caruso cv in M1 was included. The results indicated that 20 Gy irradiation exposure revealed that Spunta cultivar produced markedly high mean combined over yield during M1 (11.771 ton/fed) and M2 (10.97 ton/fed) generations than other genotypes and ranked first over all environments. It proves that Hermes could be employed as anti-stress genotypes under stress conditions (negative conditions or poor yielding). However, spunta followed by cara cv. represented a good performance in M2 production yield (10.97 and 8.51 ton/fed, respectively), slight drift from the regression line and coefficient close to 1, therefore, both cultivars were excellent between genotypes in shape of yield stability and is recommended for different conditions. According to anatomical studies, 80 % from field capacity (FC) decreased the thickness of medvein and lamina of potato cv. spunta, also, dimensions of medvein bundle and mean diameter of vessels. In conclusion, plants treated with gamma ray at level 20 and grown under 80 % FC induced prominent increase in all previous characters.

PRODUCTION OF NEW TOMATO HYBRIDS RESISTANT TO TOMATO YELLOW LEAF CURL VIRUS

seven diverse lines of tomato lines; viz, AL-1-4-1-7, HEL- 21-18, RED-8-2, EUR-6-1, D-7-4-1, JUM-14-16 and NADY-1- 2, were crossed in 7×7 a half diallel mating design. The study was made at The Experimental Farm of Fac. Environ. Agric. Sci., Arish University, North Sinai, Egypt to produce superior hybrids tolerant to TYLCV. For heterotic effect, heterosis over mid-parents, better parent and check hybrid were detected in many traits, viz.; plant height, No. of leaves, Fruit set (%) in first three clusters, hardness, T.S.S., total yield/plant and Average fruit weight. For plant height heterosis, 12 crosses exhibited significant positive values ranging from 5.83% in the cross (4x7) to 23.8% in the cross (1x5) over the check hybrid, and for number of leaves/plant 15 ones reflected mid-parents heterosis with significant values ranging from 8.23% for 1x6 to 59.4% for 2x6, suggesting dominance toward the high number/plant. Hybrids with good hardness were (1x7,2x4,2x7,3x4, and 4x7), total yield (1x5, 2x6, 2x7,4x5,4x7,5x6,5x7, and 6x7), and they also are tolerance to heat stress and TYLCV under North Sinai conditions.

Synergistic effects of inoculating AMF and foliar iron fertilizer on growth and yield of broad bean under North Sinai conditions

This work was undertaken at the Experimental Farm of Fac. Environ. Agric. Sci., Arish University, North Sinai, Egypt, during the successive winter seasons of 2016/2017 and 2017/2018. The synergistic effects of inoculating AMF and foliar iron (Fe) fertilizer on spore counts, mycorrhizal colonization, formation of nodules, plant growth and yield parameters of broad bean plant (Vicia faba L.) grown in sandy loam soil were studied. This work included two studied factors: Two mycorrhizal treatments (Inoculum AMF and Natural AMF) and five foliar Fe concentrations (0.0, 300, 400, 500 and 600 ppm) and their interactions. The obtained results revealed that application of inoculated AMF and spray with Fe at 400 ppm increased spore count and root colonization. However, total number of active nodules/plant increased with inoculated AMF and spraying iron at 600 ppm. Results indicated the superiority interaction treatment of inoculated AMF with the foliar Fe at the concentration of 500 ppm by which it recorded the highest values of plant growth traits; viz, root length, number of branches/plant, total dry weight/plant and photosynthetic pigments content in both seasons. Moreover, the same treatment recorded the highest values with all pod characters and yield, except weight of number of green seeds/pod in first season and average pod weight (g) in the second one.

Assessment of Genetic Diversity in Summer Squash Genotypes Using some Yield Traits and DNA Markers Analysis under Sinai Conditions

Fourteen summer squash genotypes were used to assess their genetic diversity and relationships using some yield traits (Fruit length, fruit diameter, fruit shape index, average fruit weight, No of fruits/plant, fruit yield, and total soluble solids %) and DNA markers (Random Amplified Polymorphic DNA, inter-simple sequence repeat, Start Codon Targeted polymorphism) analyses. Two open field trials were executed at two locations, i.e., El-Arish (L1) and Ras Sidr (L2) in the North and South Sinai-Egypt, respectively. Significant differences were observed between both locations and indicated the superiority of (L1) than (L2) in all studied traits, while the interaction between genotype and location was significant for all studied traits. The location had a major effect on the relative genotypic potential of these traits, in which the genotype × location interaction was highly significant. SQ6genotype ranked as the first in the fruit yield/plant and SQ2 for fruit diameter followed by SQ7and SQ2 for fruit shape as well as SQ13and SQ12for the number of fruits/plant in L1 and L2 locations, respectively. Additionally, high polymorphism percentage (P %) was detected using RAPD (85%), ISSR (79.25%) and SCoT (69.44). Among the 15 studied primers, OP-B17 showed the maximum P% (100%) followed by primer OP-C17 (90.9 %) which also scored the highest values for polymorphism information content, effective multiplex ratio, and marker index. In addition, OP-K01 represented the maximum value of resolving power (12.56), indicated that these primers were highly informative. Intriguingly, 55 positive and two unique negative bands were amplified, out of which (33) bands were generated by RAPD followed by SCoT (15) and ISSR (9). In this regard, OP-C17 and SQ1 genotype produced the highest number of unique marker18 and 11amplicon, respectively. Moreover, the maximum similarity was found between SQ 11 and SQ 12 indicating that both genotypes were the most similar. Cluster and PCA analysis using RAPD, ISSR, and SCoT data grouped the 14 squash genotypes into four, three and two distinct clusters, respectively. Generally, the yield traits alongside molecular results showed significant information that may be utilized to sort and relationship between the studied summer squash genotypes under different conditions

Salinity stress mitigation of some canola cultivars grown under South Sinai conditions using magnetic water technology

Salinity stresses either in irrigation water and/or soil is one of the most serious agricultural problems facing farmers in arid and semi-arid regions included Egypt. Many are as in the Sinai region depend mainly on the underground water of various degrees of salinity that prevent cultivated crops from reach to the full yield.Under these conditions,a split-plot field experiment using three canola cultivars; Pactol, Serw-4 and Serw-6under three irrigation water treatments:i) Brackish-water (BW), ii) Magnetic-BW1; brackish water after magnetization through passing a three inch static-magnetic unit,3.75 mT,produced by Delta Water Company, Egypt and iii) Magnetic-BW2;brackish water after magnetization through passing a three inch static magnetic unit, 0.75 mT,produced by Magnetic-Technologies Company, UAE,was carried out at Agricultural Experimental Station of Desert Research Centre, Ras Sidr region, South Sinai Governorate, Egypt during the 2017/18 winter season. The results showed that irrigation with M-BW1or M-BW2surpassed irrigation with BW in all tested growth parameters (plant height, branches and leaf number/plant, leaf area, dry matter of leaves, stem and total plant,and total chlorophyll); leaf anatomy(instance, mid vein and lamina thickness, length and width of leaf vascular bundle and lower and upper epidermis thickness); stem anatomy(stem diameter and thickness of cortex, xylem and phloem in addition pith diameter)and chemical analysis for mineral content (N, P, K, Mg, Fe, Cu, Zn ) at 85 days after sowing (DAS). As an average of both magnetically brackish-water treatments over tested three canola varieties, the percent of improvement compared to irrigation with brackish-water ranged between 10.78-16.02% for growth parameters, 28.33-31.76% for dry matter of plant; 15.58 -80.81% for leaf;10.71-63.88% for stems and2.42-54.48% for mineral content of leaves at 85 DAS.Reverse trends were observed in the best indicators for alleviation salinity stress (Na, and proline),where these decrease dunder both magnetic brackish water treatments by 66.08 and 43.75%, respectively (average of both magnetically brackish-water treatments compared to BW water treatment). Generally, the three tested canola varieties showed a positive response under magnetic brackish water treatments. The positive results in above-mentioned parameters of vegetative growth reflected improvement in canola yield and its components. The percent of improvement ranged between 9.35and35.98 for yield components and reached1.29,19.66 and21.30% in seed oil percentage, seeds and oil yield (kg fed-1;fed=4200m2), respectively compared to brackish water.

Screening of Tomato Genotypes under High Temperature in North Sinai

The present study was conducted at the Experimental Farm, Fac., Environ. Agric., Sci., Arish Univ., during successive summer seasons of 2018 and 2019, to screening twenty one genotypes of tomato as well as Galaxy 040 F1 as check to high temperature under North Sinai conditions. The analyses of variance for all studied traits revealed that mean squared of genotypes were highly significant under high average day/night-time temperature (34.6 oC and 23.9 oC, respectively) of two seasons. The studied lines CLN 1621F, Rio Grande and CLN2514A were the best for floral traits. However, the superior genotypes for fruit set percentage were CLN2026D and Rio Grande. Results of screening revealed that CLN2514A was the best for no. fruits/plant, CLN2413D and CLN1466EA for average fruit weight and CLN1621F for fruit yield /plant (2.84 kg). The highest content of proline recorded by CLN1621F and CLN3125L. Tomato genotypes ranked based on cumulative score to tolerant, moderately tolerant, moderately sensitive and sensitive groups. The clustering pattern of tomato entries grouped into five clusters. The clusters 1, 3 and 4 consisted of three genotypes, whereas the clusters 2 and 5 involved nine and four ones, respectively. Principal component analysis revealed that first two components participating 81.3% of total variability. The highest contribution towards total variability in PC1 and PC2 reflected by no. pollen grains/anther, pollen viability%, branches/plant, fruit set%, fruit yield/plant, average fruit weight, no. seeds/fruit and proline content traits, suggesting that these traits might be taken in concern for successful selection of tomato genotypes under high temperature.

Effect of compost extract and microelements on growth, yield and active ingredients of Trigonella foenum-graecum L. plants

This investigation was carried out to study the effect of spraying with compost extract and different chelated microelement forms, on the production seed yield, oil production and active substances of fenugreek plants under North Sinai conditions. The results showed that, all treatments recorded a highly significant increase for all studied parameters in both seasons compared with the control treatment. The highest values of all parameters the combining compost extract plus M. E. Humic form. Percentage of increase seed yield was ranged from 30 to 29%, and in fixed oil, the increase reached 131 to 116% in the first and second season, respectively. Also, there was a significant increase in the active substances inside the plant, and found a significant increase when plant treated with compost extract plus M. E. Humic form, where the percentage of increase in mucilage, protein and trigonelline was 128, 68 and 70 % in the first season, while the increase rate was 99, 64, 64% in the second season.

NEMATICIDAL EFFICACY OF BIOFUMIGATION WITH VARIOUS BRASSICA CROPS AGAINST Meloidogyne Incognita (KOFOID ET WHITE) CHITW. ON TOMATO CROP IN NORTH SINAI

Biofumigation is the practice of using Brassica green manure plants with high content of glucosinolates which enzymatically hydrolyses to nematicidal isothiocynate (ITCs) compounds. Brassica species as well as cultivars differ in both type and concentration of glucosinolate (GSLs). Under North Sinai conditions, however, the highly effective amongst Brassica species that can be effectively used are not documented for specific target yet. In this study two successive field trials were conducted using tomato (cv. Elysa) aimed at evaluating and determining the efficacy of four Brassica species (Fodder radish (Raphanus sativus) TERRANOVA H-4-169/0300), Canola (Brassica napus) (cv. Serow 4), Mustard (Brassica alba) (local commercial cultivar) and Rocket Salad (Eruca sativa((local commercial cultivar) in comparison with vydate (as positive control) and untreated (as a negative control) in suppressing root knot nematode population (Meloidogyne incognita), reproductive factor and galling index as studied nematode parameters. After 2 weeks of tomato seedlings transplanting both root knot nematode population and reproductive factor were recorded. After termination of the two experiments (12 weeks) nematode parameters and tomato plant growth attributes were recorded. Fodder radish was significantly the most effective brassica green manure in controlling root knot nematodes (Meloidogyne incognita) compare to other three studied brassicas. All studied parameters of fodder radish green manure were comparable with that of vydate. The study recommends that biofumigation methods using fodder radish green manure can be used through integrated pest management program (IPM) for both conventional and organic agriculture tomato production systems.
