Abstract: Peanut is an important oil crop in China. To introduce excellent genes of wild peanut into cultivated varieties, black peanut (A. hypogaea L.) and wild type peanut A. monticola were hybridized using distance hybridiza? tion, and a high-yielding line was obtained. The average yield per plant of this strain was 4 times higher than that of common peanut, and the plant architecture of the parent black peanut changed from erect-and-sparse-branching type to semi-sprawl-and-dense-branching type. In addition, this strain had a long growth period, large flower quan?tity, deep color, large number of pods, and the effective yield range of a single branch was about 20-25 cm. The pod type in most strains was similar to that of black peanut. The seed coat varies in color from pink to purple. There was
a significant difference in seed size. It was feasible to cultivate high-yielding peanut strain (species) by using semisprawl- and-dense branch type.

Key words: black peanut (Arachis hypogaea L. ), wild peanut (A. monticola), distant hybridization, erect type, semi-sprawl and dense-branching type, seed color, high yield
