摘　　要：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。Renong 1A,developed by crossing and successively backcrossing Fengyuan A with a spontaneous mutant with yellow green-revertible leaf isolated from T98 B /Jin 23B∥Yixiang 1B breeding population,is a new indica rice CMS line with leaf color marker. It is a new ideal leaf color marker material which exhibits the development process from yellow to green in leaf color（from leaf tip to the base） for all leaves on main culm and tillers. It is characteristic of apparent and stable leaf marker trait,good agronomic traits,high outcrossing rate,complete pollen sterility,fine grain quality and high combining ability. Renong 1A was technically identified and certified by Hainan Provincial Crop Variety Appraisal Committee in 2013.
