Effect of crossed fruit retention on seed yield and quality of tomato hybrid seed production.

摘要

To know the effect of crossed fruit retention in tomato hybrid, seed production was undertaken at Agricultural Research Station, Hanumanamatti of Haveri district in Karnataka state during 2003 and 2004. In this study, all crossed fruits, five crossed fruits, 10 crossed fruits, 15 crossed fruits and 20 crossed fruits were retained per plant. The results revealed that there was a significant difference due to number of crossed fruits retained per plant. The treatment retention of 15 crossed fruits per plant was found significantly superior with respect to fruit set, fruit yield, seed recovery and seed yield followed by 10 and 20 crossed fruits per plant, whereas five crossed fruits retention showed superiority in seed quality parameters. To get the optimum seed yield and good quality seeds, 10 to 15 fruits retention per plant was found to be optimum for DTH-1.
