水稻垩白性状的遗传研究进展

Progress in Genetic Research on Rice Chalkiness

摘要: 垩白性状是稻米最重要的品质性状之一,阐明水稻垩白性状的遗传机理十分重要.主要对水稻垩白的遗传基础、垩白数量性状位点(Quantitativetraitloci,QTL)的定位及其垩白性状相关基因的分离与克隆进行了综述,并提出了相应的遗传改良措施,以期为优质水稻育种提供参考和借鉴.

Abstract: Grain chalkiness is one of the most important traits of grain qualities in rice, it is essential to dissect the genetic basis of grain chalkiness. The genetic studies of grain chalkiness, mapping and cloning of QTL and genes associated with chalkiness were mainly reviewed, and some genetic improvement strategies of grain chalkiness were put forward,which would provide useful references for high quality rice breeding.
