Association of Genetic Parameters among Its Components in Indian Mustard (Brassica juncea L.)

Present study was conducted with 12 mustard genotypes, raised in randomized block design with three replications during the Rabi season 2023-2024 at Organic Farm, Karguanji, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (U.P.). Analysis of variance in the present investigation revealed existence of significant differences among the genotypes of mustard for all the characters studied and wide range of variability in the genotypes was observed. The highest mean performance for grain yield/ plant was observed for genotype TM-28 followed by radhika and ANG-73 indicating that these genotypes can be used in hybridization programme to achieve higher yield.

The very high heritability and very high GAM was observed in number of siliqua per plan, number of secondary branches per plant, number of total branches and number of primary branches per plant indicating the presence of additive gene action for governing of these traits and selection based on these traits will be effective. This shows that improvement of these traits during selection will simultaneously improve the yield per plant.
