Identification of Drought Tolerant Wheat Genotypes Based on Seedling Traits
Drought significantly reduces yield of many crop plants including wheat in the world. Identification of wheat genotypes that can thrive on limited water is vital to boost the wheat production of rainfed areas. Forty wheat genotypes were screened for drought tolerance using 0, 7.5, 15 and 22.5% Polyethylene Ethylene Glycol 6000 solutions at PMAS Arid Agriculture University, Rawalpindi, Pakistan ...
متن کاملNetwork Candidate Genes in Breeding for Drought Tolerant Crops
Climate change leading to increased periods of low water availability as well as increasing demands for food in the coming years makes breeding for drought tolerant crops a high priority. Plants have developed diverse strategies and mechanisms to survive drought stress. However, most of these represent drought escape or avoidance strategies like early flowering or low stomatal conductance that ...
متن کاملAssessment of agro-physiological traits for salt tolerance in drought-tolerant wheat genotypes
Salt stress is one of the major constraints for wheat cultivation inIranand leads to a considerable loss in crop yield each year. In high salinity soils, the reduced osmotic potential of soil solutes may cause physiological drought. In this study the salt tolerance of different drought-tolerant bread wheat genotypes were studied by examining various agronomic and physiological traits, inclu...
متن کاملHeterosis Analysis for Physio-Morphological Traits in Relation to Drought Tolerance in Rice (Oryza sativa L.)
Rice (Oryza sativa L.) is the most important food crop of the world; but drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. Breeding for drought tolerance is a challenging task because of the complexicity of the component traits, screening technique, environmental factors and their interaction. The major setback in drought tolerance breeding is ...
متن کاملMetabolic responses to drought stress in the tissues of drought-tolerant and drought-sensitive wheat genotype seedlings
An in-depth understanding of the effects of drought stress on plant metabolism is necessary to improve the drought tolerance of wheat and to utilize genetic resources for the development of drought stress-tolerant wheat varieties. In this study, the profiles of 58 key metabolites produced by wheat seedlings in response to drought stress were investigated to determine various physiological proce...
