Association studies for yield components in mustard (Brassica juncea and Brassica rapa) in Gangetic alluvium zone of West Bengal

The present field experiment was conducted at Teaching Farm, Mondouri of Bidhan Chandra Krishi Viswavidyalaya for two consecutive years during rabi 2016-17 and rabi 2017-18 to study the correlation and path analysis among 15 genotypes of Brassica juncea and 7 genotypes of Brassica rapa for yield and yield attributing traits grown under randomized block design with three replications. The statistical analysis was done using Windostat ® ver. 8.5 software. The genotypic correlations were observed higher value than the corresponding phenotypic correlations in both B. juncea & B. rapa over the years. The number of siliqua per plant, number of seeds per siliqua and 1000 seed weight were important yield contributing characters for both Brassica species. The plant height, 1000 seed weight, number of primary branches and number of siliqua per plant were the most pronounced characters which have a direct contribution on yield in both Brassica juncea and Brassica rapa.
