Abstract:

Using new rice varieties as tested materials, based on the trail in all pilot sites, the high yield characteristics was compared and determined in different year and pilot sites by mathematical statistics and scientific analysis. Taking the average yield of all the tested varieties in the same pilot site as the environmental index, and taking the yield of all tested varieties as dependent variable, regression analysis was done to determine the stability of each of the tested varieties, thus not noly provide a scientific basis for promotion of new rice varieties in the production, but also has guiding significance for the future breeding of new rice varieties.

Key words: rice, eco-qualification test of new varieties, high yield, stability

摘要：

依据各参试水稻新品种为材料,在各试验点与各年份试验的基础上,经过数理统计和相关因素的科学分析,依次进行比较,从而鉴定各水稻新品种在不同年份,不同地区的试验丰产性。同时以同一试验点所有参试品种产量的平均值为环境指数,称自变量,以各个参试品种的产量均值为依变量进行回归分析,以便确定每个参试品种的稳定性,为水稻新品种推广应用于生产提供科学依据,对今后选育水稻新品种具有指导意义。
