| Abstract: | 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 89.34%),good resistance to blast and bacterial leaf blight,high combining ability and good grain quality(meeting the quality standards of the 2~(nd) class food rice on NY/T 593-2002).It was technically identified in Zhejiang Province in September,2005. |
