In order to improve the panicle extrusion of photo- and thermo-sensitive sterile line ‘Pei’ai 64S’ by using elongated uppermost internode (eui) gene of the wide compatibility rice mutant ‘02428h’, a n...
Cotton breeders routinely discard progeny rows that visually appear low yielding. Such a process is essential, because it would be highly inefficient to continue to work with progeny that have no comm...
水稻野生种质优异基因分子标记定位和利用的研究进展Recent Advances in Molecular Mapping and Cloning of Useful Genes from Wild Rice and Their Application in Breeding
野生稻 分子标记 基因定位 克隆 育种
2008/1/10
摘要 野生稻由于长期处于野生状态，经受了各种灾害和不良环境的自然选择，抗逆性较强，是天然的基因库，保存着栽培稻不具有或已经消失了的特异基因。挖掘野生稻特异基因的研究日益受到重视。本文总结了近3年来在野生稻特异性状基因定位、克隆和育种利用方面的研究进展。
