Abstract:

Weather data of February (III & IV weeks) and March (I, II & III weeks) during two cropping seasons (2018-19 and 2019-20) on the incidence of LR of wheat were recorded from Satna, M.P. to find out the effect of weather factors on disease development, its intensity and response of wheat varieties against LR under these weather factors. In cropping season 2018-19 (Feb. & Mar. 2019) weather remained unfavourable (mean max., mean min. & average RH of Feb. were 44.57, 18.36 & 31.46% respectively & of Mar. were 49.05, 31.14, & 40.09% respectively) and rainfall and cloudiness were very low for development of LR therefore, disease was not occurred. In cropping season 2019-20 (Feb. & March 2020) mean max., mean mim. & average RH of Feb. were 85.64, 39.21 & 62.42% respectively & of Mar. were 84.66, 39.09, & 61.87% respectively were favourable for LR disease development therefore, disease was occurred in most of the varieties grown in the experiment. In the present study there were not more differences in mean mim., mean max. and average temp. (Feb. & March) during both cropping seasons. Total rainfall in2018-19 (Feb & March) was only 2.75mm. while in 2019-20 (Feb. & March) it was 41mm, very high as compared to Feb. & March 2019 which increased the total RH for disease development. The most significant effect on the development of LR on wheat was high RH, amount of rainfall and number of days with precipitation during mid Feb. to mid-March. It was also observed that most of LR resistance was broken down by the favourable weather conditions. Only HI 1605, JW 3288, HI 1531, HI 1500, HI 8498, HI 8713, MP 1142, HD 2864, HI 1500, HI 8627, GW 322 and Sonalika were found resistant.
