杂交稻品质性状的遗传育种研究进展

摘要

杂交稻产量性状具有极大正向杂种优势的同时又与米质性状成负相关.杂交稻碾米品质、外观品质、蒸煮食味品质和营养品质等各米质性状之问存在诸多联系.这些品质性状由不育系和恢复系共同决定.因此,可采用籼粳混合进行杂交、亚种问的基因渗透、分子选育等选育组合方式,进行优质杂交稻不育系与恢复系组配优质杂交稻组合.%This paper reviewed hybrid rice qualitative characters of genetic regularity, Summarizes the hybrid rice grind quality, appearance quality, cooking and eating quality and nutritional quality each rice quality traits and the relationship Discusses the hybrid rice breeding for quality research progress and development countermeasure.
