Genetic Study of Heterosis for Yield and Quality Components in Tomato (Solatium lycopersicum)

摘要

Nine genetically diverse tomato lines along with their 36 F,s developed through diallel mating system excluding reciprocals were evaluated with respect to yield and its components traits in randomized block design with three replications. Magnitude ofheterosis revealed that the cross combination BL 312 x EC 191536 was the most consistent for early flowering and harvest. The top best hybrids combinations for marketable yield and yield attributing traits wereBWR5xEC 191536, BT-18xBL3l2andBL312 xEC 191538.
