Abstract

Arachis glabrata Benth, variety glabrata coll. GK 10596 (PI 276233; ICG 8176) belonging to section Rhizomatosae has multiple disease resistance. Fertile hybrids between A. hypogaea L. and A. glabrata, A. duranensis Krapov &W.C. Gregory and A. glabrata and A. diogoi Hoehne and A. glabrata were produced. Introgression of DNA from A. glabrata into A. hypogaea, A. duranensis and A. diogoi was analyzed by isozyme and RAPD analyses. Hybrids were backcrossed and BC1 seeds were obtained in all the three hybrids. Hybrids were evaluated for the transfer of disease resistance genes from A. glabrata, which was confirmed. RAPD analysis with several primers showed that DNA fragment pattern were not simply represented, instead there were new bands and several parental bands were absent in the interspecific derivatives.
