the objective of this investigation was to evaluate the magnitude of g × e interaction effects on durum wheat grain yield and to identify superior genotypes adapted to the test environments. twenty improved durum wheat genotypes were tested in five locations over three growing seasons. combined anova indicated that the effect of year (y) was significant and that of the location (l) was not, but...

In wheat, a lack of genetic diversity between breeding lines has been recognized as a significant block to future yield increases. Species belonging to bread wheat's secondary and tertiary gene pools harbour a much greater level of genetic variability, and are an important source of genes to broaden its genetic base. Introgression of novel genes from progenitors and related species has been wid...

Germination characteristics, early seedling growth and seed metabolic efficiency of four wheat genotypes (BARI Gom 28, BARI 29, BAW 1177 ESWYT 29) were evaluated under 15% polyethylene glycol (PEG-6000) induced osmotic stress (-3 bar). characteristics (germination rate, co-efficient germination vigor index), shoot root length, dry weight, decreased by PEG than control treatment. But the degree ...

Plants, being sessile in nature, have developed mechanisms to cope with high salt concentrations in the soil. In this study, the effects of NaCl (50-200 mM) on expression of high-affinity potassium transporters (HKTs), antioxidant enzymes and their isozyme profiles were investigated in two contrasting bread wheat (Triticum aestivum L.) genotypes viz., HD2329 (salt-sensitive) and Kharchia65 (sal...

Abstract The appropriate timing of the accumulation biogenic amines is very important during cold acclimation due to their direct protective role and involvement in signaling processes. time course changes amount six them was compared a 3-week period freezing tolerant sensitive genotype rye, barley wheat. In general, greater faster cold-induced increase amine content observed genotypes three sp...

Wheat is an important winter cereal of Nepal but drought limits its production as 34.44% wheat producing area under non-irrigated environment. The identification high yielding potential varieties with stable performance environment may be the way forward to cope limited productivity. So, in this study, effect genotype by interaction on yield fourteen and two promising lines environmental condit...

Abstract This study was conducted to evaluate the role of oxidative stress in roots of eight wheat genotypes with different drought tolerance, subjected to drought stress. For analyzing the changes of antioxidant enzymes, native PAGE analyses of protein extract were performed. The roots of wheat seedlings showed one unambiguous isoform of superoxide dismutase (SOD) and catalase (CAT). Eight iso...

in order to study stress tolerance indices and identifying tolerance genotypes to drought stress condition 16 genotypes of durum wheat were assessed in a randomized complete block design with four replications under two irrigated and rainfed conditions in the research station located in west of iran ilam in 2006- 2007. results showed that variation in among durum wheat genotypes under irrigated...

Drought is one of the most important factors limiting crop yields around the world. Drought stress in plants, the change (increase or decrease) in the production of plant proteins. This research was carried out using bread wheat genotypes. For evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....
