Genetic diversity in Bolivian landrace lines of groundnut (Arachis hypogaea L.)

Published on

Bolivian landraces of groundnut were analyzed for
morphological and molecular diversity as well as for late
leaf spot resistance, an important fungal disease of
groundnut. The study revealed large diversity with respect
to seed color, size and weight. There was variation for
oleic and linolic acid contents ratio too. Molecular studies
using SSR markers showed large diversity between
Bolivian landrace lines and improved cultivars of
groundnut. Late leaf spot resistance studied through
detached leaf bioassay showed moderate to high levels
of resistance, which can be exploited for the improvement
of cultivated groundnut.

Keywords: Groundnut, Bolivian landrace, morphological diversity, molecular diversity, LLS resistance.
