选育早熟高产大豆新品种,必须对原始材料或品种的产量构成因素及其间的关系有所了解。大豆品种的产量性状是遗传型和环境因素相互作用的表型结果。它既有随着年份、地点以及农艺技术条件而发生的变动性,同时还有着相对的稳定性。本文试图在高纬度条件下,阐明大豆早熟品种的产量性状构成及其变异,以及性状间的关系,为培育早熟高产大豆品种在产量选择的予期进展上,
Breeding of early maturity and high yield of new varieties of soybeans, must be raw materials or varieties of yield components and the relationship between understanding. The yield traits of soybean varieties are phenotypic consequences of the interaction between genetic and environmental factors. It has both variability along with the year, place and agronomic conditions, as well as relative stability. This paper attempts to elucidate the composition and variation of yield traits and the relationship between traits of early-maturing soybean varieties at high latitudes. In order to cultivate early maturity and high-yielding soybean varieties,
