摘　　要：利用2002～2005年湖南省各级晚稻试验统计资料,通过变异系数和回归系数,分别对中优281和对照威优46的稳定性和适应性进行分析和比较,结果表明,中优281的稳定性和适应性跟对照威优46相当,但综合性状尤其米质要明显优于对照,是一个较为理想的杂交晚稻新组合,适宜在湖南省作双季晚稻种植。Based on experimental statistical data of late rice at all levels in Hunan during 2002～2005,the stability and adaptability of hybrid rice variety zhongyou281 and the control（weiyou46） were analyzed and compared through the variation coefficient and regression coefficient,the results indicated that the stability and adaptability of hybrid rice variety zhongyou281 was similar to the control（weiyou46）,but its comprehensive characters especially in grain quality was significantly better than that of control group,so it is a comparatively ideal new late hybrid rice combination,is suitable to plant for double cropping rice in Hunan.
