中文摘要:
      广两优931是广东省农科院水稻研究所用自育两系不育系广3S 与自选的抗稻瘟病恢复系GR931组配育成的两系杂交稻新组合,该组合经过广东省两年区试和1年生产试验,表现产量与对照优优122相当,米质达国标和省标优质3 级,中抗稻瘟病,感白叶枯病,耐寒性中强,2012 年1月通过广东省品种审定,适宜广东省粤北稻作区和中北稻作区晚造、中北稻作区早造种植。
英文摘要:
      Guang-Liang-You 931 is a newly-developed rice hybrid from a temperature-sensitive genic male sterility (TGMS) of rice Guang 3S crossed to a restorer GR931 with resistance to blast. The regional ecological adaptability tests in two years and the yielding trial in one year in Guang dong province showed that the characteristic of yielding potential of hybrid was similar to CK You-you 122, 3-class quality grain rice was determined by both the Rice Grain Quality Standards of the Agricultural Department of China and the Rice Grain Quality Standards of Guangdong province. It has been examined and approved by the Crops Approval Committee of Guang-dong province in January 2012,and could be planted to the mid-northern rice cropping district of the province in the early season and to the northern and mid-northern districts in the late season.
