Abstract:
Combining ability analysis was undertaken diallel cross set in ten parents and their 45F1 for yield components and oil content in rapeseed (Brassica juncea L.) and revealed that the mean squares of general combining ability (gca) was highly significant for all the characters except for number of seed per siliqua and white rust,while the mean squares for specific combining ability (sca) was highly significant for most of the characters studies except number of seed per siliqua and 1000 seed weight that suggesting the importance of both additive and dominance component. In present investigation Bio-133-04 was observed to be the good general combiner for oil content, plant height, length of siliqua,1000 seeds weight,oil content and erucic acid. BBM07-1 was observed as good general combiner for number of siliqua per plant, seed yield per plant, oil content and erucic acid. Parent Vardan and Shivani showed highly significant positive general combining ability effects at one and five percent probability level respectively for oil content. The maximum general combining ability effect for erucic acid showed by parent Kranti and BBM07-1. The best two crosses selected on the basis of specific combining ability were RRH-615×RRH-605, RH-0305×Shivani and Bio-133×BBM07-1 for seed yield per plant. Two top crosses selected on the basis of specific combining ability were RH-0447×RRH-615, Kranti×Shivani, for oil content percent. Overall study revealed that both additive and non-additive gene actions were important in the expression of the characters under studied. These crosses could be exploited for further improvement for seed yield, yield attributing characters and oil content
