Abstract
An attempt was made to study the genetic diversity among the 65 genotypes of faba bean.
Significant difference for various traits indicated substantial amount of variability existed among the
genotypes for various traits. High heritability coupled with high genetic advance was observed for seed
yield, 100 seed weight, pod length, number of pods per plant, number of branches per plant, number of
clusters per plant and days to 50% flowering. In general phenotypic correlation coefficients were
higher in magnitude than their genotypic correlation coefficient. Seed yield per plant was found to be
positively and significantly correlated with days to 50% flowering, days to maturity, number of
branches per plant, number of cluster per plant, number of pods per plant, pods length, number of seeds
per pod and 100 seed weight. Path analysis revealed that characters such as 100 seed weight and
number of pods per plant were the major component traits of seed yield and hence these characters
should be given priority in selection in view of their high heritability coupled with high genetic
advance also. Following non hiericial eucleadean cluster analysis all 65 genotypes were grouped into 9
clusters with variable number of genotypes. On the the basis of data on genetic diversity and mean
performance of matric traits nine diverse and superior genotypes namely EC-628955, EC-628942, EC-
628937, EC-628936, EC-591755, EC-3134, EC-2112, EC-628930 and EC-591776 were identified as
promising for most of the traits. So these genotypes may be used in further crop improvement
programme.
