241 Effect of Scion-Rootstock Combinations on Premature Fruit Drop in Mango

Abstract

Studies were conducted to determine the effect of scion-rootstock combinations on premature fruit drop. Ten-year-old trees of the varieties Parvin and Tommy Atkins grafted on Eldon, Malda, Colombo Kidney, Julie, and Cuban were used. The number of prematurely dropped fruits was counted weekly for 8 consecutive weeks after flowering. A smaller fruit drop index was observed when `Parvin' was grafted on Malda, Julie, and Cuban than when grafted on Colombo Kidney. There was no significant difference in fruit drop index between Eldon and Colombo Kidney. Fruit drop index was greater in `Parvin' than in `Tommy Atkins'.
