【摘要】 利用国家黄淮南片4省21个试验点的区域试验数据，对赛德麦8号的株高、最高分蘖数、分蘖成穗率、穗粒数、有效穗数、千粒质量、产量等主要农艺性状进行分析。结果表明，赛德麦8号穗粒数偏小，但有效穗数稳、千粒质量高，是一个高产品种；该品种株高偏低，抗倒伏能力强，分蘖成穗率高，易形成大群体，适应性广、综合抗性强，适宜在黄淮南片大面积推广种植利用。更多还原

【Abstract】 We analyzed the main agronomic traits of Saidemai No.8, including plant height, maximum tiller number, percentage of effective tillers, grain number per spike, effective panicle number, 1 000-grain weight and yield based on regional tested data from 21experimental sites of 4 provinces in southern Huanghuai area. The results show that the variety has a relatively small number of grains per spike, but has stable effective panicles and high 1 000-grain weight, and is a high-yield variety. This variety has low plant height and strong lodging resistance and high percentage of effective tillers, and is potential to form large population. It has wide adaptability and strong comprehensive resistance. Therefore, Saidemai No.8 is suitable for large-scale spreading and planting in southern Huanghuai area.更多还原
