Heat stability of winter wheat depends on cultivars, timing

发布时间：2024-01-29 21:37

　　Heat stress negatively affects wheat production in many regions of the world. At present, sensitivity to heat stress remains one of the least understood aspects of wheat genetics and breeding, and measures for preventing heat stress are understudied. In this study, we used three cultivars of winter wheat(GY2018, SL02-1 and SY20) to evaluate the effect of heat stress at different days after anthesis(DAA) on yield and quality. Heat stability of the cultivars were analyzed and evaluated for the eff...
