Wheat (Triticum aestivum L.), a staple food crop is of great commercial importance. Its production is restricted due to various abiotic stresses. There are indications that the wheat production is consistently limited by terminal heat stress. Here, performance of forty genotypes of wheat was undertaken for assessment of direct selection parameters (variability, heritability and genetic advance) and their relation with heat tolerance. | Nội dung Text Developing a selection criterion for terminal heat tolerance in bread wheat based on various mopho-physiological traits
