Renong 1Ais a new indica CMS line with leaf color marker, developed by testcrossing and continuous backcrossing, using a spontaneous mutant with vires-cent-yel ow leaf isolated from the progenies of T98B /Jin 23B ... Renong 1Ais a new indica CMS line with leaf color marker, developed by testcrossing and continuous backcrossing, using a spontaneous mutant with vires-cent-yel ow leaf isolated from the progenies of T98B /Jin 23B ×Yixiang 1B as the male parent, and Fengyuan A as the female parent. Al the chlorotic leaves of Renong 1A turn green in later developmental stages from leaf tip to base. This is the reason why Renong 1A is a new ideal leaf color marker material in indica rice. It shows apparent and stable leaf marker trait, good agronomic traits, high outcross-ing rate, complete pol en sterility, fine grain quality and high combining ability. Renong 1A has already been technical y identified and certified by Hainan Provincial Crop Variety Appraisal Committee in 2013. 展开更多
