ABSTRACT

Wheat is one of the important staple crops of the world. Its grain yield is affected by various factors including genotype and planting time. An experiment was conducted to study the yield performance of 10 different wheat advanced genotypes (PR-133, PR-135, PR-136, PR-137, PR-138, PR-139, PR-140, Khaista-17, Gulzar-19 and Pirsabak-19) at different sowing times of 15-days interval. A pooled analysis across the same environment revealed a significant difference (P ≥ 0.01) for all the parameters i.e., days to heading, days interval, plant height, flag leaf area, tillers m-2, spike length, spikelet spike-1, grain spike-1, thousand grain weight, grain yield and biological yield across three planting dates i.e., early, normal, and late respectively. Differences between wheat genotypes and genotype-environment interaction were also highly significant (P≥ 0.01) for studied traits, indicating that genotypes performed differently in three sowing times. Under early, normal and late planting, genotypes PR-138, PR-140 and Gulzar-19 had the highest grain yield respectively. PR-138 performed outstandingly across three sowing times for seed yield. Hence, it is concluded from the present study that delayed sowing progressively decreases the yield performance of the studied genotypes and the most suitable sowing time is from 15th October to 15th November.
