摘要
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.
热农1A是从T98B/金23B∥宜香1B杂交后代群体中获得的转绿型新叶黄化自然突变株系为父本,以丰源A为母本,经测交和连续多代回交转育而成的籼稻叶色标记不育系。热农1A全生育期每片叶都经历新叶黄化,随后从叶尖向叶基部由黄转绿的动态发育过程,是一种新的理想型水稻叶色标记材料;该不育系具有标记性状明显、农艺性状优良、花粉败育彻底、异交结实率高、米质较优、配合力好等特点,于2013年通过海南省农作物品种审定委员会审定。
