ABSTRACT
The seven inbred lines found promising in earlier studies were used for making crosses in full diallel fashion. These 42 crosses along with seven parents and four standard checks were evaluated in a randomized block design with two replications during kharif 2011. Analysis of variance for means revealed significant differences for all the eleven characters studied. Parents vs. hybrids interaction mean square were also significant for all the characters, indicating the variability in parents and hybrids. The parent EC-5587014 and IC-32118 proved to be good general combiner for nine characters, while EC-558766 and GPM-213 for seven characters and EC-558707 for eight characters. The parents GPM-213, EC-5587014, IC-32118, EC-558707 and EC-558766 could be utilized in the breeding programme for obtaining transgresive segregants.
