Abstract

The study was conducted to check the impact of variable date of sowing for climate resilience in two consecutive years 2021-2022 and 2022-2023 at Faisalabad. Three different dates of sowing 25th of October, 10th, and 20th of November were selected for screening of sixteen Desi chickpea, genotypes, and commercial variety Bittal-2016 as check. Data were recorded for days to 50% flowering, plant height, primary and secondary branches, pods per plant, 100-grain weight, and grain yield kg/ha. The highest grain yield per ha in both years was produced by D-20004 and D-20007. The comparison of sowing dates manifested that on 25th October the plant health remained good and was less affected by climate and produced enhanced grain yield. On the 10th of November and 20th of November, plant growth remained stunted and bear the low number of pods per plant ultimately producing a low yield. The selected lines can be used in breeding programs for the development of climate-resilient chickpea genotypes.

评估鹰嘴豆品种在不同播种期的气候适应能力和产量稳定性

该研究旨在检查 2021-2022 年和 2022-2023 年连续两年在费萨拉巴德不同播种日期对气候适应性的影响。选择了 10 月 25 日、11 月 10 日和 20 日三个不同的播种日期，对 16 个 Desi 鹰嘴豆基因型进行筛选，并以商业品种 Bittal-2016 作为对照。记录的数据包括50%开花天数、株高、主枝和副主枝、每株豆荚数、百粒重和每公顷谷物产量公斤数。在这两年中，D-20004 和 D-20007 的每公顷谷物产量最高。播种期的比较表明，10 月 25 日的植株生长状况良好，受气候影响较小，谷物产量较高。而在 11 月 10 日和 11 月 20 日，植株生长仍然迟缓，单株结荚数较少，最终产量较低。所选品系可用于育种计划，以开发气候适应性强的鹰嘴豆基因型。
