摘 要: 中国水稻研究所用优质早籼材料浙农996作母本与优质保持系金23B杂交,于F3代选米质优良的株系与优质不育系中9A测交,经多代连续回交育成优质不育系中3A。中3A育性稳定,柱头外露率高达89.34%,配合力强,稻米品质达NY/T 593-2002食用稻品种品质2级标准,中抗稻瘟病和白叶枯病,具有广阔的生产应用前景,于2005年9月通过浙江省科技厅组织的专家鉴定。 Zhong 3A, developed from crossing Zhong 9A to Zhenong 996/Jin 23B and successively backcrossing its filial male sterile plants to Zhenong 996/Jin 23B, is a new indica CMS line with good grain quality and strong disease resistance. It showed stable and complete male sterility, vigorous stigma with a high exsertion rate (as high as 89134% ), good resistance to blast and bacterial leaf blight, high combining ability and good grain quality (meeting the quality standards of the 2nd class food rice on NY/T 593 - 2002).
