Genetic divergence in novel determinate variants of resynthesized Indian mustard (Brassica juncea (L.) Czern & Coss)

Published on

A field experiment was conducted to study the genetic
diversity in 125 genotypes with determinate plant growth
habit in Brassica juncea along with 3 indeterminate check
varieties PBR 357, Coral 432 and DMH 1 as per alpha lattice
design with two replications at PAU, Ludhiana. Mahalanobis’
D2 analysis grouped genotypes into 12 clusters. Clusters 1,
2 and 6 were considered ideal for future breeding efforts
based on inter genotypic distance and other agronomic
performance. Out of the fifteen traits evaluated, yield (kg/
ha) and pods/plant contributed the most towards the
divergence (81.06% and 18.58%, respectively).
