GENETIC DIVERGENCE AMONG RICE BEAN (VIGNA UNBELLATA (THUMB) OWHI AND OHASHI) CULTIVARS OF MANIPUR HILLS

Published on

Genetic divergence of thirty-one local·rice bean cultivars of Manipur hills and
genotype CXM12P3 from the N.B.P.G.R, was studied. Based on Mahalanobis D2
values, the genotypes were classified into five different clusters following Tocher's
method. Depending upon the inteKluster distance, cluster mean value and mean
per se performance of the best genotype within the cluster, cross combinations
involving different selected parents for various breeding objectives were suggested:
RBMI x RBMIO for· shorter plant height, early f\owering and higher number of
seeds per pod, RBMIO x RBM17 for higher primary branches, per plant, RBMll x
RBM17 for higher number of pods per plant·and grain yield· pet' plant, RBM31 x
RBM17 for higher length of pod and seed weight.
