| Abstract: | Chang 410-2 A,derived from the cross between CMS line Wuyunjing 7 A and a stable line of(Changnongjing 5/Chang 01-11 B)F5 and the subsequent successive backcrosses,is a new BT-type japonica CMS line with long grains in rice developed by Changshu Agricultural Science Research Institute of Jiangsu Province and Jiangsu Zhongjiang Seed Industry Co.Ltd..In September,2018,it was technically identified by Jiangsu Provincial Crop Variety Appraisal Committee.It is characteristic of stable male sterility,good grain quality,early flowering time,wide glume-opening angle,partial stigma exsertion,high outcrossing rate,easy production of hybrid seed and male sterile line seed.Its hybrid Changyoujing 7(Chang 410-2 A/CR-928),belonging to a long-grain japonica hybrid rice,was registered and released for commercial production by Jiangsu Provincial Crop Variety Appraisal Committee in March,2019. |
