Variation in progenies of an Arachis hypogaea X diploid wild species hybrid



Variation in progenies of an Arachis hypogaea X diploid wild species hybrid



Euphytica 28(3): 675-684



Derivatives of a cross between cultivated peanuts, A. hypogaea L. (2n = 40), and the wild species collection GKP 10017 (2n = 20) were compared morphologically, for leafspot [Cercospora arachidicola, Cercosporidium] resistance and for yield. The effects of wild species germ plasm on the A. hypogaea genome were determined. The sterile F1 hybrid which resulted from crossing the 2 spp. was treated with colchicine to restore fertility at the 6x ploidy level. The resulting hexaploid was cytologically unstable and progeny lost chromosomes until stability was regained at the 2n = 40 chromosome level. Forty-seven characters were used to analyze the variation among plants in the tetraploid interspecific hybrid population. The plants were compared to 4 cultivated lines plus GKP 10017. Many hybrids were intermediate to the 2 parents in morphology. Individual traits such as growth habit, pod and seed size, elongation of the constricted area between pods, nodulation and leaflet size were altered by the presence of GKP 10017 germ plasm in many of the hybrid plants. C. arachidicola Hori and Cercosporidium personatum (Berk. and Curt.) Deighton resistances were evaluated for all plants. Several hybrids had few lesions due to either leafspot pathogen. In addition, 24 large-seeded interspecific hybrid selections were compared to the cultivated variety NC 5 for yield. Five selections were superior to both parents at P = 0.01. Morphology, disease resistances and yield apparently were greatly influenced by the wild species GKP 10017 germ plasm in plants of the interspecific hybrid population. The potentials of using wild species for improvement of the cultivated peanut are discussed.
