一、前言晚籼是我国南方省区大面积应用的水稻品种类型。水稻产量,从构成因素来分析,取决于每亩穗数、每穗实粒数,千粒重等性状的综合表现;从内外因素来分析,决定于品种基因型与特定环境条件的相互作用。六十年代Eberha rt提出册稳定性参数测定新品种的适应性,我国农业科技工作者也在这方面作了不少探讨,并开始应用这类参数分析新品种的生产和应用价值。品种区域试验是鉴定品种丰产性和适应
I. Preface Late indica rice is a large variety of rice varieties used in the southern provinces of our country. The yield of rice, which is analyzed from the compositional factors, depends on the comprehensive performance of traits per spike, grains per spike, and 1000-grain weight. The analysis of internal and external factors determines the interaction between the cultivars’ genotypes and specific environmental conditions. In the 1960s Eberhart put forward the stability parameters of the book to determine the adaptability of new varieties, agricultural science and technology workers in our country also made a lot of discussions in this regard, and began to use such parameters analysis of new varieties of production and application value. Regional testing of varieties is to identify varieties of high yield and adaptation
