杂交稻区域化试验鉴定结果是推广新组合的重要依据。以往评价一个新组合的适应性能主要是根据各试点小区产量,进行复因子方差分析,按照组合×地点互作效应大小来判断的。但是,评价一个新组合的使用价值,不仅要看产量,还要考虑熟期,抗性、品质。更何况我国幅员广大,自然条件,经济条件各地尽然不同。对某地区丰产是最重要的,而在另一个地区可能早熟才是最重要的。因此评价一个新组合的适应性,不仅要综合四个因素表现,
Identification of hybrid rice regionalization test results is an important basis for the promotion of new combinations. In the past, the adaptability of a new combination was mainly evaluated according to the yield of each pilot plot by the analysis of the multiple factor analysis of variance according to the size of the combination × spot interaction effect. However, evaluating the value of a new portfolio depends not only on yield but also on maturity, resistance and quality. Not to mention the vastness of our country, natural conditions, economic conditions vary from place to place. The most important for a region’s high yield, while precocious in another area is the most important. Therefore, the evaluation of a new combination of adaptability, not only to synthesize the four factors,
