对一个新品种,我们不但要求其具有高产潜力,同时也希望能稳产。所以现代的品种区域试验,不但要分析品种的产量差异,同时也十分重视稳定性。这里所要求的稳定只是与农业生产有关的性状,如产量、品质、成熟期等,在不同的环境条件下保持相对稳定的状态。所以,品种稳定性实际上是指一个品种能调节其遗传型或表现型的状态以适应于变动的环境,使其某些经济性状保持相对稳定的能力。稳定性好的品种能在一定地区和不同年份内产生高而稳定的经济效益。稳定性好的品种具 For a new breed, we not only demand that it have high yield potential, but also hope to stabilize production. Therefore, modern varieties of regional trials, not only to analyze the yield differences in varieties, but also attaches great importance to stability. The stability required here is only the traits associated with agricultural production, such as yield, quality, maturity, etc., which remain relatively stable under different environmental conditions. Therefore, the stability of varieties actually refers to a variety can adjust its genetic or phenotypic status to adapt to the changing environment, so that some of its economic traits to maintain a relatively stable capacity. Stable varieties can produce high and stable economic benefits in certain regions and years. Variety of good stability
