Genetic divergence in landraces of common bean (Phaseolus vulgaris L.) from the Nilgiris

Published on

Genetic diversity of common bean (Phaseolus vulgaris L.)
was assessed based on morphological traits and RAPD
markers. The principal component analysis identified eight
components with eigenvalue above 1.0 and together
explained 84.35% of the total variation. RAPD based
dendrogram showed two major groups corresponding to
the Andean and Mesoamerican gene pools. These bean
landraces retain a considerable level of heterogeneity. Our
results suggest that a deep knowledge of germplasm is the
best strategy for preserving the diversity of common bean
available with tribal farmers in remote villages of Nilgiri
hills.

Keywords: Genetic diversity, morphological markers, Phaseolus vulgaris, RAPD markers
