Effect of late sowing on yield and yield attributes of wheat genotypes in EIGP

Terminal heat stress is one of the major causes of low productivity in eastern region of India. The aim of present experiment was to evaluate the performance of wheat genotypes for terminal heat stress tolerance on the basis of yield attributes. Ten wheat varieties (HI 1563, HD 2987, Kundan, Raj 4238, GW 273, NW 1012, DBW 14, Halna, HD 2733 and HD 2967) were taken for evaluation. Performances of wheat genotypes were judged on the basis of yield and yield attributes. Study revealed that there were decline in 1000 grain weight and final yield from timely sown to very late sown condition. Although less reduction in yield and yield contributing traits were observed in wheat genotypes HD 2987, NW 1012, Kundan and DBW 14. This finding may be of use to heat stress condition thus will boost wheat production under late sown condition
