Morphological characterization and correlation analysis of F cross of Indian 2:3 mustard × East-European mustard for yield traits in Brassica juncea

Abstract

The Indian mustard (Brassica juncea L.) is one of most important oilseed crops in the country. Three hundred and fiftynine F plants were morphologically characterized for different traits, which served as the foundation for the 2 development of F population as a result of crossing of Pusa Mahak (Indian mustard) with Primus (East-European 3 mustard) genotypes. The characters studied were days to 50% flowering, plant height, main shoot length, number of primary and secondary branches, number of siliquae per plant, siliqua length, seed yield per plant etc. Results revealed that plant height was significantly correlated with number of secondary branches (r =0.94), number of siliquae on main shoot (r =0.89), seed yield per plant (r =0.51) and main shoot length (r =0.48) in F population. Similarly, the number of 3 siliquae on the main shoot detected a high correlation with number of secondary branches (r =0.83), main shoot length (r =0.47) and seed yield per plant (r =0.46). Awide range of trait values were obtained for the entire population of F2 and F3 plants, as indicated by the data analysis
