| Abstract: | Q4A, derived from the cross of Q2A///Q1B/Nongxiang 16//Shuangkang 7702, is a new WA-type fine quality indica CMS line in rice developed by Chongqing Zhongyi Seeds Co. Ltd. With good outcrossing habits, fine grain quality (meeting the 3~(rd) class of standards on NY/T 593-2002 of Rice Qualities for Food by the Ministry of Agriculture of China) and medium susceptibility to blast, it was technically identified in Chongqing in August, 2007. Its hybrid combination Q You 12 (Q4A/R72) was certified for release to commercial production by Chongqing Crop Variety Appraisal Committee in January, 2008. |
