摘    要:本文探讨了我国大陆甘蔗远缘杂交的研究和利用现状。已获得远缘杂种的组合有 :热带种×割手密、热带种×大茎野生种、竹蔗×栽培种、热带种×斑茅、甘蔗×河八王、甘蔗×滇蔗茅、甘蔗×五节芒、高梁×甘蔗、甘蔗×白茅和甘蔗×竹。培育了一些含我国野生种质资源的亲本材料如崖城 58- 4 3、崖城 62 - 4 0、崖城 71- 374、崖城 73- 2 2 6、崖城 73- 512等 ,利用这些亲本材料育成了一些优良品种如粤糖 64- 395、珠江 75- 53、粤农 76- 191、福农 79- 2 3、赣蔗 65- 54、赣蔗 64- 137、桂糖 82 - 338和桂糖 83- 4 92。远缘杂交研究和利用中遇到的主要问题是杂交不育、部分种 (品种 )难开花、杂种不育和种质资源研究不深入。

Abstract:This paper is an approach to the research and advance of the distanthybridization of sugarcane,China mainland.The distant hybrids were between S.officinarum(Saccharum) and S.spontaneum,S.robusteum,S.sinensis,E.aurendinum,M.horidulus,N.porphyrocoma,E. rokii,lmperata,Bambusa. A number of parent materials which contain the germplasm of the wild resources in China mainland were obtained.By meansof these parents a few of recommended varieties,such as Yangtang6 4-395 ,Zhujiang75 -5 3,Yangnong76 -1 91 ,FA79-2 3,Ganghe 6 5 -5 42 ,6 4-1 37,Guitang82 -338and 83-4 92 ,were bred. The main porblems found in the re- search and utilization of the distant hybridization in China mainland are cross-mcompatibility, difficult flowering of some species(varieties) ,hybrid sterility and lack of the further research of genetic resources.
