Preliminary Studies of Apomixis and Fixation of Heterosis in Sorghum

doi:10.3321/j.issn:1000-7091.1991.03.006

Abstract

Abstract: The present paper dealt with breeding vybrids from apomictic line R473 and other materials. The result showed that crossing sexual and faculative apomictic material only improved the latter and vybrids couldn’t be formed| vybrids forms only by crossing different derived faculative apornicts, combining these materials invarious pattern could get high ireqency apomicts and finaly, nearly non-segregated vybrids could be obtained. The methed of breeding vybrids also discussed here.

Key words: Sorghum, Apomixis, Hcterosis
