杂交晚稻“协优赣26号”的选育与应用

Breeding and Application of New Hybrid Rice Combination “Xieyougan 26”

以“协青早A”为母本 ,自育恢复系“C1 42 9”为父本进行配组 ,成功选育出杂交晚稻新组合“协优赣 2 6号”。 1 998、1 999年该组合参加南方稻区晚籼中迟熟组区试 ,平均产量分别为 6 .87t/hm2 和 6 .94t/hm2 。在推广和应用中 ,“协优赣 2 6号”表现高产、稳产、米质优、综合抗性强和制种产量高等特点 ,适合江西中南部地区作二晚种植。提出了“协优赣 2 6号”

By crossing between “Xieqingzao A”(female parent) and restoring line “C1429”(male parent) which was bred by the author,a new hybrid rice combination“Xieyougan 26” was successfully bred. The average yield of “Xieyougan 26” in the regional tests for middle-late maturing late indica rice varieties in southern rice region in 1998 and 1999 is 6.87t/hm\+2 and 6.94t/hm\+2 respectively. This combination shows high and stable yield,good rice quality,strong comprehensive resistance and high yield of seed production in popularization and utilization. It is suitable to plant “Xieyougan 26” as double-cropping late rice in the middle and south of Jiangxi. The culture and seed production techniques of this combination were presented in the paper.\;
