Susceptibility of Pigeonpea Cultivars of Different Maturity Groups to Botrytis Gray Mould.

摘要: Some 57 pigeon pea (Cajanus cajan) lines of different maturity durations were compared for susceptibility to Botrytis cinerea at Pantnagar during the 1990-91, 1991-92 and 1992-93 crop seasons. In 26 early to medium maturing lines which flowered in 83-117 days and matured in 161-196 days disease development was low (less than 10 buds damaged). B. cinerea infection in the 22 medium to late maturing lines was very high in all 3 seasons. Lines which flowered after 161-196 days and matured after 265-304 days exhibited the highest bud damage (up to 93%).
