Abstract:

An experiment was conducted to study the nature and magnitude of heterosis for seed yield and its fifteen yield attributing components along with oil content. Four females and five males were crossed in a line x tester fashion to develop 20 F1 hybrids. The resulted 20 F1 hybrids and their nine parents along with two standard checks (AKC-1 and 48-1) were evaluated in randomized block design with three replications at the field of AICRP for Dryland Agriculture, Dr. PDKV, Akola during kharif 2015-16. The genotypes, parents and crosses revealed high degree of differences for all the characters under study. The highest useful heterosis of 39.66 per cent over the check variety AKC-1 and 53.05 per cent over the check variety 48-1 for seed yield was observed indicating the scope of its exploitation further in the breeding programme of this crop. The cross AKD1 X 561-2 has been found to be promising and can be utilized after confirming its potential on large scale.
