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。
Hot peasant 1A was obtained from the cross of T98B / Jin23B∥Yixiang 1B population and was used as the male parent to turn green new leaf yellow natural mutants. After Fengyuan A was used as female parent, Transgenic sterile indica rice leaf color marker CMS. It is a new type of ideal paddy leaf color marker material that every leaf of the hothouse cultivar 1A undergone new leaf yellowing during the whole growth period and then from yellow tip to green leaf tip. In 2013, it passed the Hainan Crop Variety Approval Committee for its validation of marked traits, excellent agronomic traits, thorough pollen abortion, high rate of outcrossing and fruiting, high quality of rice and good combining ability.
