Cytological Studies on the Interspecific Hybrid of Arachis hypogaea×Arachis duranensis

Abstract

A hybrid, between Arachis hypogaea and A. duranensis was obtained. Study of meiosis revealed a maximum association of 10 bivalents and 10 univalents at meta-phase I. This shows that one genome is common in both the species supporting the alloploid origin of cultivated species. The hybrid was completely sterile with high degree of pollen sterility. Attempts are being made to transfer resistance for tikka leaf spot disease from A. duranensis to A. hypogaea.
