In bread wheat (Triticum aestivum L. em. Thell.), development of thermal stress tolerant cultivars and realization of potential at yield in hot climate is enshrined goal of our breeding program. By keeping the above fact in view, the present study was conducted in two environments . normal and late sown condition with 10 diverse genotypes, their 45 F1’s and F2’s to magnify the yield level of wheat in high temperature areas by selecting stress tolerant parents and cross combinations. | Nội dung Text Estimation of heat stress tolerance for yield and its contributing attributes in bread wheat
