Selection for drought tolerance typically involves evaluating genotypes for either high yield potential or stable performance under drought stress. In order to select drought tolerant varieties of bread wheat an experiment was conducted in a randomized complete block design (RCBD) with two replications during the growing season 2014-2018. Eight drought tolerance indices including stress tolerance index (STI), geometric mean productivity (GMP), mean productivity index (MP), stress susceptibility index (SSI), tolerance index (TOL), yield index (YI), yield stability index (YSI) and drought resist

Global wheat production and productivity are facing threats due to recurring droughts caused by climate change. To combat these challenges, it is important to develop drought-tolerant wheat cultivars that can withstand drought and heat stress in marginal production environments. This can be achieved by exploring wheat crops inherent genetic variations and environmental adaptations. Understanding the various mechanisms such as genetics, physiology, biochemistry, and environment and their interactions is crucial in improving drought tolerance in wheat. This paper will summarize the genetic gains

Scarcity of water has been a serious agricultural hindrance to crop productivity since antiquity. Drought-stressed loss in wheat yield likely exceeds losses from all other causes, since both the severity and duration of the stress are censorious. Here, we have reviewed the effects of drought stress on the morphological, physiological, and biochemical attributes along with the growth impacts, water relations, and photosynthesis impacts in wheat. This review also illustrates the mechanism of drought resistance in wheat. Historical drought years in Nepal have been identified and the yield losses

This study conducted field experiments using two winter wheat varieties, the drought-sensitive variety Jimai 22 and the drought-resistant variety Chang 6878, aiming to investigate the effects of Streptomyces pactum Act12 inoculation on photosynthetic characteristics, physiological parameters, and yield traits during the jointing,

The article presents the results of the evaluation of varieties two seasonal soft wheat according to the parameters of drought and heat resistance. During the research, 25 varieties two seasonal soft wheat were studied. These varieties and lines were assessed for resistance first by the degree of seed germination in osmotic solutions. As a result of research on high drought tolerance, samples KR19-19thDSBWYT-29782 and KR20-20thDSBWYT-12 were selected. The study, as well as plant leaves, assessed the drought and heat resistance of samples during the period earing. Based on these data, KR19-19th

SummaryDisks of hard wheat (Triticum durum Desf.) leaves subjected to rapid desiccation over 4 h showed noticeable changes in the shape of the in vivo chlorophyll fluorescence induction curves. In drought-sensitive varieties (such as Claridoc), water stress resulted in a strong inhibition of the slow fluorescence induction transients. In particular, the fluorescence quenching rate was markedly decreased in water-stressed leaf disks. In contrast, leaves of drought-resistant varieties (such as Aouedj) showed only minor changes in chlorophyll fluorescence. The results of this investigation sugges

Rye is a diploid crop with many outstanding traits and is very important as a source of new traits for improving wheat and triticale. Since the demand for rye is relatively low, it is desirable to grow it mainly for grain in areas where it is difficult to grow wheat and other useful crops. In addition, the advantage of rye over other cereal plants is that it is considered one of the plants that is more resistant to drought. But drought stress is one of the factors that significantly affects all physiological processes of the rye plant. In particular, it causes a certain decrease in the yield o
