抗病优质杂交水稻不育系蓉18A的高产制种技术

摘要

Rong 18A, bred by Crop Research Institute, Chengdu Academy of Agriculture and Forestry Sciences is a new blast-highly resistant and high-combining ability hybrid rice sterile line. It is currently one of the male sterile lines in Sichuan Province which combine well high grain quality and rice blast resistance. More than 20 combinations of Rong 18A have passed the national and provincial variety identification. Combined with the climate conditions in Chengdu, the key points of highyielding seed production techniques for Rong18A are analyzed and summarized in this paper.%杂交水稻不育系蓉18A是成都市农林科学院作物研究所经过多年选育的高抗稻瘟病,高配合力新的水稻不育系,系四川省目前米质和抗稻瘟病这2个性状结合得最好的骨干不育系之一,蓉18A配组已经选育20余个组合通过国家及省级品种审定.主要结合成都市气候条件,分析总结蓉18A杂交水稻制种高产的技术要点.
