Habitat and Ecology
A. cardenasii is a diploid species from Robora, Bolivia and is highly resistant to the root-knot nematode (Meloidogyne arenaria) and many other pathogens and insects (Stalker et al. 2002)
Wild Arachis spp. are important because they show resistence and even apparent immunity to diseases such as rust (Puccinia arachidis Speg.), web blotch (Phoma arachidicola Marasas, Pauer & Boerema), early leaf spot (Cercospora arachidicola S.Hori) are late leaf spot (Cercosporidium personatum Berk. & M.A.Curtis) which might have a great impact on the worldwide production of Arachis hypogaea L., commonly known as the peanut or groundnut, which is an important and widespread food legume.
The diploid (2n=20) wild species, Arachis cardenasii, has been hybridized with A. hypogaea and the hybrids progenies exhibited high level of resistance to the disease previously mentioned (Varman 2000).
