应用水稻特异株型材料 7N5改良系 R4 5 6与不同质源的两系不育系和三系不育系进行配组 ,调查杂交组合的结实率及产量。结果表明 :7N5改良系 R4 5 6分别与两系不育系和三系不育系配组都具有较高的恢复力和配合力。其配组的 3个新杂交组合在不同地区有不同的产量表现
Application of the line-specific CMS line 7N5 improved line R4 5 6 with two-line CMS lines and CMS lines from different sources to investigate the seed setting rate and yield of hybrid combinations. The results showed that the improved strain R4 5 6 of 7N5 had higher resilience and combining ability with the two-line and three-line CMS lines, respectively. The three new hybrid combinations with their different groups have different yield performance
