SCREENING OF GERMPLASMS FOR RESISTANCE TO BOTRYTIS GRAY MOLD OF CHICKPEA (Pages : 16 - 21)
M.A. HOSSAIN, M.E.A. MONDOL, M.H. RASHID, H. RAHMAN AND M.R. HASNATThe experiment was conducted at RARS, BARI, Rahmatpur, Barisal to find out the resistant source of Botrytis Gray Mold (BGM) of chickpea under natural epiphytotic condition. Fifty two chickpea germplasms/variety were used and finally 23 germplasms/variety were selected during 2012-2013. Out of 23 chickpea germplasms, 18 germplasms showed highly resistant (HR) and 5 germplasms observed resistant (R) at flowering stage, one germplasm (BD-6041) showed highly resistant (HR) and 22 germplasms showed resistant (R) at pod setting stage, 22 germplasms found resistant (R) and one variety (BARI Chickpea-5) showed Highly Susceptible (HS) reaction at the maturity stage. Out of tested 23 germplasms/varieties the tallest (56.50 cm) plant was found in check variety BARI Chickpea 9 and the shortest plant (29.40 cm) was recorded in case of germplasm BD-6346. The maximum duration for maturity (137 days) was recorded in germplasm BD-6352 and the minimum duration (134.5 days) was recorded in germplasm BD-6036. The highest 100-seed weight was 24.50 g (BARI Chickpea-9) and the lowest 100-seed weight was 8.00 g (BD-6042). The maximum yield was recorded 1660.0 kg/ha from germplasm BD-6352 and the minimum yield was recorded 340.0 kg/ha from germplasm BD-6036 and BD-6041.Download
