Abstract
The study conducted to check the impact of changing climate on different date of sowing, disease resistance and yield stability in 2020-2021 at Faisalabad. Three different date of sowing 15th of October 25th of October and 10th of November were selected for screening of one hundred and sixty four, chickpea genotypes (Desi and Kabuli advance lines and commercial varieties as check). The highest grain yield per plot produced by Desi advance line, D-15027 and in Kabuli, advance line K-01525. The comparison of sowing dates manifested that at 25th October the plant health remained good and was less effected with wilt and produced enhanced grain yield. The germplasm of chickpea (Cicer arietinum L.) were screened for the source of resistance against chickpea blight (Ascochyta rabiei) and wilt (Fusariun oxysporum f.sp.Ciceri). Out of 164 genotypes/varieties, six genotypes/varieties were found resistant, 66 were found moderately resistant and the remaining showed susceptible to highly susceptible type of reactions. Whereas in case of wilt, two lines (D-15027&K-01525) were showed moderately resistant behavior to disease. The resistant and moderately resistant sources in chickpea blight and wilt can further be exploited in breeding program for the development of disease resistant commercial cultivars.
