阐述了杂交稻稻米品质的特点以及各品质性状的遗传特征 ,指出选育优质杂交组合必须以收集优质亲本资源为前提 ,并通过杂交选育、回交选育以及群体改良等手段加以改进 ,在创造出更为优良的亲本 (不育系与恢复系 )之后 ,采用优质亲本与中等或中等偏上米质的亲本配组 ,可以选育出适合广大群众所需要的普食型高产优质组合 ;采用优质亲本配优质亲本 ,可以选育出符合特殊消费和出口要求的高档优质组合
The characteristics of the quality of hybrid rice and the genetic characteristics of the quality traits were described. It was pointed out that the selection of high quality hybrid combinations must be based on the collection of high quality parental resources, improved by hybridization breeding, backcross selection and population improvement. After creating better parents (CMS and restorer lines), using high-quality parents with medium or medium top-quality parental parents can breed high-yielding and high-quality combinations suitable for the needs of the general public. High-quality parents with high-quality parents, you can breed in line with special consumption and export requirements of high-grade high-quality combination
