采用传统分析法和高稳系数法对2011年湖北省棉花区域试验10个参试品种(组合)的丰产性和稳产性进行了分析,研究了参试品种(组合)的平均产量(x-)、标准差(S)、变异系数(CV)、回归系数(b)和高稳系数(HSC).结果表明,HSC与x呈显著正相关,HSC与S呈负相关但不显著、HSC与CV呈显著负相关,b与x-相关性不强,b与S、CV呈极显著正相关.参试品种(组合)的标准差、变异系数、回归系数与产量稳定性有关,与产量高低无关,而产量平均值只能反映产量高低而与产量稳定性无关,高稳系数能综合表示参试品种(组合)的高产稳产性.%The high and stability production quality of 10 cotton varieties for regional test in Hubei province was analyzed using high stable coefficient method and traditional method and the average yield (x-), standard deviation (S), coefficient of variation (CV), regression coefficient (b), and high stable coefficient (HSC) of these cultivars were studied. The results showed that HSC had significant positive correlation with x-, but had significant negative correlation with CV, and had a negative correlation trend with S. b had obvious positive correlation with S and CV, but had no obvious correlation with x-. The S, CV, and b of these cotton varieties were related with the yield stability, but not with the yield level, the average yield only reflected the yield level but not the yield stability. However, the high stable coefficient could reflect both the yield level and the yield stability.
