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

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.
