| Abstract: | Le 3 A, developed from testcrossing an elite single plant selected from the F3 generation of the cross between IR Super Rice and Jin 23 B to the DA-type indica CMS line Xieqingzao A and followed by successive backcrossing over years, is a new indica CMS line in rice. It is characteristic of high combining ability, good outcrossing habits and incomplete dominance of early maturity, and its hybrid combinations are of good grain quality, early maturity and strong lodging resistance. In August 2012, Le 3 A was technically identified by Sichuan Provincial Crop Variety Appraisal Committee, and its F1 hybrids, Le 3 You 727 and Le 3 You 2275, were registered and released for commercial production in Sichuan Province in September, 2019. |
