以农业部认定的6个超级杂交稻组合、3个省级主推超级杂交稻组合、2个苗头超级杂交稻组合和普通高产杂交稻汕优63(对照)为材料,研究了超级杂交稻在长江流域7个生态试验点的产量稳定性.结果表明,超级杂交稻准两优527、红莲优6号、C两优87和Y两优1号4个组合表现超高产且在各试验点产量稳定性较高,结实率高而稳定,在80%以上,表现出良好的生态适应性;其它组合则在特定的生态条件下表现较高的产量和结实率.对超级杂交稻的生态适应性及其分类进行了讨论.

The yield stability of super hybrid rice combinations planted at seven ecological locations of the Yangtze River Valley was studied with six super hybrid rice varieties issued by the Ministry of Agriculture, China, three widely-used provincial super hybrid rice varieties, two promising super hybrid rice varieties and the high-yielding hybrid rice variety Shanyou 63 （Check） as the materials. The results showed that four super hybrid rice varieties including Zhunliangyou 527, Honglianyou 6, C Liangyou 87 and Y Liangyou 1 had both high yield and...
