Evaluation of potato (Solanum tuberosum) genotypes under heat stress condition

L.) genotypes were evaluated in early crop season (75 days) at experimental field of ICAR-Central Potato Research Institute, Regional Station, Modipuram, Meerut, Uttar Pradesh, during 2020 and 2021. Significant differences were recorded among for tuber yield and tuber attributes like plant vigour (1–5 scale), foliage maturity (1–5 scale), tuber colour, tuber shape, eye depth and flash colour. The pooled results of 2020 and 2021 crop seasons indicated that eight genotypes namely Kufri Mohan (260 g), Kufri Lima (256 g), CP4149 (252g), Kufri Garima (241g), Kufri Bahar (239 g), CP3273 (236 g), Kufri Neelkanth (221 g), CP4143 (212 g), CP1326 (208 g) and Kufri Arun (207 g), were found high-yielding in term of total tuber yield/plant. The highest marketable tuber yield/plant was recorded in Kufri Lima (234g), CP4149 (230 g), Kufri Mohan (225 g), CP3273 (213 g), Kufri Bahar (211 g), Kufri Garima (208 g), CP4143 (190 g), Kufri Neelkanth (182 g), Atlantic (178 g) and Kufri Arun (177 g). The genotypes, CP1931, CP3319, CP3322, CP3450, CP3470, CP3499, CP4149, CP4238, Kufri Garima, Kufri Lima, Kufri Surya and Lady Rossetta, were found highly tolerant with 0% hopper burn incidence. Most of the genotypes were highly tolerant with 0% mite damage incidence except CP3495, CP3341and CP3472 (20%) and Kufri Sindhuri and Kufri Pukhraj (40%). On an overall basis CP4149, Kufri Mohan, Kufri Garima and Kufri Lima were found promising for high plant stand, plant vigour, marketable/total tuber yield, marketable/total tuber number and nil/low incidence of hopper and mite burn.

Field Evaluation of Potato N Needs Following Forage Legumes

In an attempt to quantify the nitrogen (N) contribution from forage legumes to succeeding potatoes, trials were conducted on 28 Wisconsin alfalfa or red clover fields. Potato total yield and crop value were determined following in-season fertilizer N applications of 0 to 280 kg ha−1. Only 2 of the 12 alfalfa sites and 6 of the 16 red clover sites responded to applied fertilizer N when total yield was considered. However, using crop value, responses were seen at 5 alfalfa and 7 red clover sites. Apparent fertilizer replacement value ranged from 0 to 224 kg N ha−1 for both alfalfa and red clover, and averaged 129 or 102 kg N ha−1 for the respective forages. Due to the wide variation, consideration of criteria in addition to preceding crop is necessary to accurately estimate potato N needs following legume forages. Use of the petiole nitrate-N test did not improve the predictive capability.

Evaluation of potato (Solanum tuberosum L.) genotypes for resistance to late blight at Sinana Southeastern Ethiopia

Late blight caused by Phytophthora infestans (Mont.) de Bary, is one of the most significant constraints to potato production in Bale high lands and other regions of Ethiopia. Hence, this requires to develop high yielding and late blight resistant varieties. Therefore, this study was conducted to determine host resistance of potato against Phytophthora infestans in order to develop late blight resistant/tolerant genotypes. The experiment was laid out in randomized complete block design with three replications at Sinana Agricultural Research Center during 2014 main cropping season. The genotypes showed highly significant (P&lt;0.01) differences for all the characters studied. Genotypes exhibited wide ranges of mean values for all characters. The highest total tuber yield (46.1 t ha-1) was obtained from the advanced clone, CIP-392640.524 followed by Belete (41 t ha-1). Late blight appeared early on farmer's cultivar Kellacho (48 days after planting) and late on advanced clones CIP- 399062.102(74 days after planting). Percent severity index (PSI) and area under disease progress curve (AUDPC) ranged from 33.91 to 91.67% and 105 to 2370, respectively. Eleven newly introduced clones and the released variety "Belete" recorded PSI 33 to 39.7% and AUDPC 105 to 264.1. Hence, these genotypes can be categorized as moderately resistant. The study revealed the presence of considerable variability in tested genotypes for economically important traits and the higher chance of selecting genotypes with high yield and moderately resistant to late blight. However, it appears that further evaluation of genotypes across seasons and locations to identify genotypes that could be released as varieties seem to be quite pertinent.Int. J. Agril. Res.

Physico-chemical and sensory evaluation of potato (Solanum tuberosum L.) after irradiation.

This work evaluated the effects of ionizing radiation on the physico-chemical and sensory characteristics of the potato cultivar Ágata (Solanum tuberosum L.), including budding and deterioration, with the end goal of increasing shelf life. For this, four groups of samples were harvested at the maturation stage. Three of them were separately exposed to a Co-60 source, receiving respective doses of 0.10, 0.15 and 2.00 kGy, while the non-irradiated group was kept as a control. All samples were stored for 35 days at 24 °C (± 2) and at 39% relative humidity. The following aspects were evaluated: budding, rot, loss of weight, texture, flesh color, moisture, external and internal appearance, aroma, soluble solids, titratable acidity, vitamin C, protein, starch and glucose. The results indicated that 0.15 kGy was the most effective dose to reduce sprouting and post-harvest losses, under the conditions studied.

Evaluation of Potato (Solanumtuberosum L.)Varieties for Yield and Yield Components in Eastern Ethiopia

Potato is one of the strategic crops, enhancing food security and economic benefits to Ethiopia. Ethiopia has suitable edaphic and climatic conditions for the production of potatoes. But lack of well adapted cultivars is one of a production problems that account for low yield and small area cropped to the nation. Therefore, this study was conducted at Haramaya, Hirna and Arberekete to evaluate yield and yield component of 16 released potato varieties (Moti, Belete, Bubu, Ararsa, Gudenie, Bule, Gabissa, Marachare, Harchassa, Gera, Gorrebella, Guassa, Jalenie, Bedassa, Zemen & Chiro) and two local cultivars (Bette & Jarso).The experiment was laid out as a Randomized Complete Block Design with three replications. The results revealed the statistically significant variations in most of the traits. The highest total yield (56.52t/ha) and marketable tuber yield (53.97t/ha) recorded for Gera variety grown at Hirna, average tuber weight (105.24gm) and large sized tuber number (56.3%) for Belete grown at Haramaya large sized tuber weight (80.93%) for Belete grown at Hirna, marketable tuber number (95.83%) for Gera grown at Haramaya and unmarketable tuber weight (55.26t/ha) were observed for Bule grown at Hirna. The high mean small size tuber number (62.75%) for Jarso at Haramaya, small sized tuber weight (37.42%) were observed for Marachere grown at Hirna, medium sized tuber number (41.72%) for Zemen grown at Arberekete and medium sized tuber weight (49.13%) were observed for Bedasa variety grown at Arberekete. Finally, the result of the study reviled that the genotype and growing environment has a great influence on yield and yield components of potato tubers.

Methods of Evaluation and Selection of Potato Forms Resistant to PVM, PVY and PVX

Various methodical approaches for the discovery and selection of virus-resistant potato forms are analysed. The optimum methods and conditions of PVM, PVY and PVX plant inoculation by evaluation to immunity are revealed, a possibility of realisation of complex inoculations on Lycopersicon esculentum Mill. (cv Nevsky) infected by PVM + PVX mixture, what accelerates an evaluation and increases its efficiency. The necessity of the controlled infectious backgrounds creation by evaluation of potato selection material for field (relative resistance to PVM + PVY + PVX complex) is shown.

Evaluation of potato (Solanum tuberosum) cultivars for productivity, nitrogen requirement and eco-friendly indices under different nitrogen levels

A field experiment was conducted during the winter ( rabi) seasons of 201112 and 201213 at Adisaptagram Block Seed Farm, Hooghly, West Bengal, to optimize the potato ( Solanum tuberosum L ) cultivars and nitrogen lev- . els for growth attributes, tuber yield, nitrogen-use efficiency, sustainability, eco-friendliness and economics in new . alluvial zone of West Bengal. Fifteen treatment combinations, viz 3 potato cultivars (Kufri Himalini, Kufri Shailja and Kufri Jyoti) and 5 N doses (0, 75, 150, 225 and 300 kg N/ha) were laid out in a factorial randomized block de- sign with 4 replications. Kufri Himalini recorded the maximum tuber yield (31.3 t/ha), which was significantly higher than Kufri Shailja (26.6 t/ha) and Kufri Jyoti (24.1 t/ha). Correlation between tuber yield and plant height (R2=0.73), tuber yield and dry matter accumulation (R2=0.84), tuber yield and tuber bulking rate (R2=0.75) and tu- ber yield and total N uptake (R2=0.62) were significant. The correlation study between nitrogen and tuber yield showed high degree of correlation (R2=0.984) and N was derived as 202.6 kg N/ha for optimum economic yield. opt. Agronomic efficiency (AE ) and physiological efficiency (PE ) was more in Kufri Himalini at all N levels. There was N N a positive balance of nitrogen in all the treatments except one treatment (Kufri Jyoti with 300 kg N/ha). Kufri Himalini fertilized with 300 kg N/ha gave the highest net returns ( 1,45,156/ha) and benefit: cost ratio (2.58) with least difference from 225 kg N/ha, while the negative response was recorded in the control. Kufri Shailja potato was more eco-friendly, as its index was 18.4% higher than Kufri Jyoti. Kufri Shailja required 18.4% less applica- tion of fertilizer N to give the highest yield obtained by Kufri Jyoti (30.94 t/ha). So, for obtaining a given yield, less amount of fertilizer is being put to soil and hence comparatively less amount of N is being lost to the environment.

Evaluation of potato seed tubers from different sources in the Punjab plain of Pakistan

Inability to produce large quantities of high quality, relatively diseasefree potato seed is a major constraint to providing economic support to a highly important and rapidly expanding potato production industry in Pakistan. Studies were undertaken for 5 years to evaluate productivity of seed of cultivars Red Bad, Ajax, Atica, Patrones, Montana, Cosima, Desiree, and Cardinal grown at five environmentally diverse locations in Pakistan versus seed of the same cultivars imported from Europe. The productivity trials were conducted during the autumn and spring seasons at the Ayub Agricultural Research Institute, Faisalabad (Punjab Plains). The results from the 5-year test period indicate that seed of each of the cultivars produced in the high hills (Baluchistan, Northwest Frontier Province) and during autumn (September to December) in the Punjab Plains, the latter cold stored until the following September, are equally as productive as seed imported from Europe.

In vitro digestibility and calculated PER as rapid methods for the nutritional evaluation of potato protein

Protein Efficiency Ratios (PER) have been determined for hybrid potato selections by feeding flake diets to rats; more rapid and inexpensive tests are required by breeding programs which select for improved potato protein. Two more recent methods, in vitro digestibility (IVD) and calculated PER utilizing discriminant computed PER (DC-PER) and computed PER (C-PER), were studied for their potential in evaluation of the nutritional quality of potato. Albumin (A) and two subfractions, acid soluble and insoluble (ASA and AIA), were studied, as well as flakes. The average IVD for albumin was 68.9%, for ASA was 67.5% and for AIA was 77.5%. Digested proteins were identified by electrophoresis before and after enzyme treatment. The higher IVD values for AIA were probably due to the presence of protease inhibitors among the ASA proteins. IVD differences among groups of hybrids were found and a reasonable correlation (r=0.71*) of these values with flake PER values was observed. The DC-PER values ranged from 2.64 to 2.79, these values were larger than those observed in feeding trials; additional genotypes need to be studied before this method can be proposed for potato evaluation. The presence of protease inhibitors in the albumin samples is indicated, because the average IVD value of 68 increased to about 84 after the albumins were heated prior to IVD determinations.
