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(Quantitative trait loci,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.
Chalky traits are one of the most important quality traits in rice and it is very important to elucidate the genetic mechanism of chalky traits in rice.It mainly deals with the genetic basis of chalkiness and the location of quantitative trait loci (QTL) The isolation and cloning of genes related to chalky traits were reviewed, and the corresponding genetic improvement measures were put forward to provide reference and reference for high quality rice breeding.
