Summary: | The present study investigated genetic diversity among 47 advanced field pea breeding lines. For all of the traits
investigated, ANOVA revealed significant differences between the lines. The highest PCV, GCV and high heritability as
well as a high genetic advance per cent of mean were recorded for the number of primary branches/plants, clusters/
plant and pods/plant. The present collection of 47 lines was sorted into seventeen clusters after a genetic divergence
analysis using Mahalanobis’s D2 analysis. Cluster XII and XIII (43.62) had the greatest average inter-cluster distance,
while cluster VII had the greatest intra-cluster distance (12.66). The highest percentage contribution of features to
divergence was biological yield/plant, followed by the number of primary branches/plants. For most of the genotypes,
clusters XV and XVII had higher cluster means. As a result, lines corresponding to these clusters can be utilised in the
breeding programme in the future.
