质核远缘杂交,最先是作为取得雄性不育胞质而用于作物“三系”育种的研究。六十年代玉米T型胞质对大小斑病的严重感染,引起育种家们对胞质系育种的兴趣。1973年美国V.G.Merer登记发放了包括有中棉(G.arboreum)、草棉(G.herbaceum)、异常棉(G.anomalum)、长萼棉(G.longicalyx)、哈克尼西棉(G.harknesii)、海岛棉(G.barbadenese)和夏威夷棉(G.tomentosum)7个棉种胞质的陆地棉品系(其中中棉、异常棉和哈克尼西棉三种胞质系是作为雄性不育系发放),为研究棉花胞质系育种较早的报道,但还未 Nucleus distant hybridization, first as a male sterile cytoplasm for crop “three lines” breeding research. In the 1960s, T-cytoplasm of maize was seriously infected by the plaque spot and caused the breeders’ interest in cytoplasm breeding. In 1973, the United States registered and issued VGMerer products including G. arboreum, G. herbaceum, G. anomalum, G. longicalyx, .harknesii), G. barbadenese and G. tomentosum (three of which were cytoplasmic male sterile CMS release), an earlier report on cotton cytoplasmic breeding has not been reported yet
