【摘要】 为了解国际稻作研究所杂交稻新组合的产量潜力及在云南的适应性,2003年在云南涛源(高产生态条件) 和蒙自(大田生产条件)2个试验点,以国际稻作研究所(IRRI)的9个杂交籼稻新组合为材料,以中国大面积推广组合汕优63为对照,对其产量潜力及适应性进行初步研究,结果表明:部分杂交稻新组合(IR66284H、 IR77266H、IR77843H)具有不亚于汕优63的高产潜力,而且能适应云南生产生态条件。
【Abstract】 In order to know the yield potential and adaptation of new hybrids bred by International Rice Research Institute (IRRI),9 new indica rice hybrids introduced from IRRI were employed to evaluate their yield potential and adaptation to Yunnan,China under different environments:high-yield ecological condition(Taoyuan)and farmer’s field(Mengzi).The results indicated that some new rice hybrids,such as IR66284H,IR77266H and IR77843H,had similar yield potential to Shanyou 63,the widest planting hybrid in China,and could adapt to Yunnan typical indica rice production condition.
