多年来,我国在进行新品种区试中,基本上都用T测验方法进行品种差异显著性测验。其方法虽然简单但效果不理想,往往只能筛选出高产品种,对产量不高,但稳定性好的品种无法鉴定,甚至出现误判现象。“稳定性参数”的统计方法既考虑到品种的遗传,又体现出环境因素的效应,能较全面地反映出一个品种的特性。在1986年全省早杂区试中我们引用了“稳定性参数”的估算方法,对参试的五个组合进行具体分析,对它们各自的丰产性、稳定性、适应性作了全面评价,从中选出较理想的组合,从
Over the years, our country in the new variety of regional trials, basically using the T test method to test the significance of differences in varieties. Although the method is simple but its effect is not satisfactory, it is often only able to screen out high-yielding varieties. However, the yield is not high, but the varieties with good stability can not be identified, and even the phenomenon of misjudgment occurs. The statistical method of “stability parameter” takes into account not only the inheritance of varieties but also the effect of environmental factors, which can more fully reflect the characteristics of a variety. In the test of early Zongzi of the province in 1986, we quoted the estimation method of “stability parameter”, carried on the concrete analysis to the five combinations of the test, made a comprehensive evaluation of their respective richness, stability and adaptability, Choose the ideal combination from
