本文提出了测定水稻品种对环境稳定性的一个新参数,采用这一参数对美国加利福尼亚州多年多点的水稻品种整米率进行稳定性分析的结果表明,稳定性与熟期类型在统计上有一定的相关性,即整米率稳定性依晚熟品种、早熟品种、特早熟品种而顺序降低,回归分析说明整米率的稳定性有随整米率的提高而增加的趋向,本文还讨论了稳定性系数的优点和局限性。
In this paper, we propose a new parameter for determining the stability of rice varieties to the environment. Using this parameter to analyze the stability of whole rice rate of rice varieties in California for many years, we found that the stability and maturity types are statistically The correlation of the whole rice rate stability decreased according to the sequence of late-maturing varieties, precocious varieties and especially precocious varieties. Regression analysis showed that the stability of whole rice rate increased with the increase of whole rice percentage. This article also discussed The advantages and limitations of the stability factor.
