黑龙江省主栽糯稻遗传背景研究

Research on Genetic Background of Main Cultivated Glutinous Rice in Heilongjiang Province

选取黑龙江省近年审定的糯稻品种,对其遗传背景进行分析,试图挖掘其系谱中的骨干亲本,为糯稻品种的选育和改良提供理论依据。结果表明,大部分通过审定的糯稻品种都含有日本水稻的血缘;一些骨干亲本能够直接育成或衍生出糯稻品种,为优秀的糯稻品种选育奠定了基础。今后,应加强骨干亲本的筛选和利用,以为糯稻品种的选育和改良提供帮助。

The genetic backgrounds of main glutinous rice were analyzed in this study, which were approved in recent years in Heilongjiang Province. The author tries to find out the mainstay parents in pedigree, provides theoretical basis for glutinous rice variety breeding and improvement. The results showed that most of the glutinous rice approved contain the consanguinity of Japanese rice, some mainstay parents can directly breed or derived glutinous rice varieties and lay the foundations for the breeding of glutinous rice. The authors suggested that future breeding program, emphysives on the selection and utilization of mainstay parents.
