Abstract

Sixty mungbean genotypes were evaluated for genetic
divergence under limited moisture condition during summer
season. Based on 19 phenotypic markers, hierarchical
cluster analysis identified nine clusters containing one to
15 genotypes. Principal factor analysis reduced the nineteen
variables into six principal components explaining 74.66%
of the total variability. Seed yield per plot, harvest index
and number of seeds per pod loaded highly on the PC 1;
photochemical efficiency and canopy temperature
depression on PC 4 and membrane stability index, total
chlorophyll content and 100 seed weight on PC 5.
Genotypes MH 810, MH 721, MH 736, M 395, SML 668, Pusa
9972 were found promising with regard to yield and drought
tolerance traits. Out of 31 SSR primers used, only 18 were
polymorphic and amplified 74 alleles. Primer CEDG067
exhibited maximum PIC value (0.84). The NTSYS-pc UPGMA
cluster analysis divided the sixty genotypes into nine
distinct groups.
