TAILIEUCHUNG - Gene action for quantitative traits through generation mean analysis in Indian mustard (Brassica juncea L.)

The adequacy of different genetic models and nature and magnitude of gene effects responsible for the expression of seed yield and important yield contributing characters were studied in mustard. 6 generations of two crosses viz; MRNJ 88-1 X JMWR 9081-1 (Family A), MRNJ 131 X JMWR 9081-2 (Family B) sown in Compact Family Block Design were investigated. Data recorded showed the predominance of both Main effect (additive-dominance) and interaction effect for most of the yield and component traits except in number of primary branches per plant and number of secondary branches per plant where the role of main gene effect was distinct. Presence of interaction effects and duplicate epistasis suggested the possibilities of obtaining transgressive segregants in later generations. The role of fixable and non-fixable gene action in controlling different yield and component traits was also apparent. The present findings will help in deciding effective selection and breeding strategies to get desired improvement in seed yield and related traits. | Gene action for quantitative traits through generation mean analysis in Indian mustard (Brassica juncea L.)
