Abstract:
Optimum sowing dates provide favorable temperatures to obtain the maximum yield of wheat. The varietal selection also plays a vital role in obtaining higher wheat production. Different wheat lines (MY902, MY1501, MY291-4, MY409-4) with two local checks Wadan-17 and Khaista-17 were sown on various sowing dates (1st October, 15th October, 1st November, and 15th November). The experiment was laid out under a split-plot design with three replications at Agronomy Research Farm, The University of Agriculture Peshawar, Pakistan during Rabi season 2021-2022. Sowing dates were allocated to the main plots while wheat lines were placed in the sub plots. Among sowing dates, sowing on 1st November performed better in terms of tillers (372 m-2), leaf area (41 cm2), plant height (94.6 cm), spike length (12 cm), spikelets spike-1 (22), grains spike-1 (68), thousand-grain weight (53 g), biological yield (13102 kg ha-1) and grain yield (4716 kg ha-1) while the harvest index (36%) was maximum in early sowing on 1st of October. Wheat line MY1501 recorded maximum days to emergence (14), jointing (67), booting (115), anthesis (134), and physiological maturity (174) while emergence (12), jointing (59), booting (116), anthesis (127) and physiological maturity (164) were earlier in local check Khaista-17. Maximum tillers (381 m-2), plant height (101.8 cm), and spike length (12 cm) were recorded for wheat line MY291-4 while leaf area (44 cm2) was more in wheat line MY902. Yield and yield components i.e. spikelets spike1 (22), grains spike-1 (67), 1000 grain weight (54 g), and grain yield (4522 kg ha-1) were higher for wheat line MY2914 and biological yield (12452 kg ha-1) was found maximum for wheat line MY409-4 followed by local check Wadan-17. It is concluded from the results that early and late planting of wheat lines caused a reduction in all the growth and yield attributes while the optimum sowing date i.e.1st November resulted in higher yield and yield components of wheat lines. Similarly, Chinese wheat lines MY291-4 and MY409-4 resulted in higher yield and yield components as compared to Pakistani improved wheat varieties.
