Abstract

A study was conducted to estimate heterosis of 21 tomato cross combinations involving seven parents at the experimental field of Olericulture Division of HRC, BARI during the winter season of 2005-2006. Analysis of variance indicated highly significant differences for all the characters suggesting the presence of genetic variability among the studied materials. Three combinations (P2 × P3, P3 × P4, P3 × P5) showed significant early flowering, while two P1 × P7 (16.67%) and P1 × P2 (12.44%) for individual fruit weight. In the study, the cross combinations P4 × P7 (62.31%), P2 × P6 (37.44%), P4 × P6 (34.77%), P2 × P7 (33.67%), P3 × P7 (32.09%), and P3 × P4 (29.82%) manifested higher heterosis over better parent for yield per plant.

Keywords: Heterosis; tomato; genetic variability.
