摘要
2010—2014年黑龙江省审定通过的84个水稻品种中,第一积温带审定品种追溯三代的骨干亲本有辽粳5号、合江20、上育397、庄内32、秋光,追溯两代为五优稻1号;第二积温带主要骨干亲本有绥粳4号、绥粳3号、空育131、垦稻10;第三积温带的骨干亲本有绥粳4号、绥粳3号、空育131;第四积温带审定水稻品种6个,空育131衍生2个品种。由这些骨干亲本再向上追溯的骨干亲本为松前、藤系138、富士光、藤系137、虾夷、合江20等。
The pedigree of 84 rice varieties approved in Heilongjiang province from 2010 to 2014 were analyzed in this study. The results showed that the backbone parents of the first accumulated temperature zone varieties had Liaojing 5, Hejiang 20, Zhuangnei 32,Qiuguang and Wuyoudao 1. the backbone parents of the second accumulated temperature zone varieties had Suigeng 4, Suigeng 3,Kongyu 131 and Kendao 10; the backbone parents of the third accumulated temperature zone varities had Suigeng 4, Suigeng 3,Kongyu 131. 6 rice varieties have been authorized in 2010—2014 in the fourth accumulated temperature zone, Kongyu 131 derives two varieties.
