Abstract

Yellow sarson is the premium oilseeds crop because of having high oil content with good shelf quality. The crop has been not explored much as not grown in extensive area across country. Crop is cultivated mostly in northern and eastern part of country. Not much improvement work has been done in yellow sarson and there is ample scope for its improvement and further exploitation. In the present investigation parents were evaluated on the basis of their combining ability and identified to be used as parent in the breeding programme. Fourteen parents were selected on the basis of their performance and diversity. 10 were taken as female lines and 4 as testers. 40 crosses were made and crosses along with parental line were evaluated on RBD. Results revealed the presence of dominance for all the traits. The average degree of dominance indicated the presence of non-fixable gene action. Narrow sense heritability (h2n) found low for all the traits which further confirmed the prevale

Conclusion

On the basis of research finding and discussion obtained from the present investigation, non-additive genetic variance was found to be more prominent as compare to additive genetic variance for most of the characters which suggested perceptible advance of maintaining heterozygosity or restoring it at the end of the breeding programme. Potential parents and crosses have been identified based on relevant multiple parameters. The parents can be utilized as donor for specific trait and crosses can be utilized through heterosis breeding by adopting most appropriate breeding strategies suggested during the study for overall improvement of yellow sarson. A long term breeding programme can also be initiated where the selective parents can be involved for improvement of specific character. Pedigree method can be practiced to have desirable outcome with maximum improvement. Future scope: Combining ability analysis is an excellent method for identification of parents for development of heterot
