本试验研究大豆不同成熟期类型亲本组合,F_1代光合速率的优势。其目的是进一步明确第一代光合速率优势情况,为开展F_1代优势与共它各世代间的关系打下初步基础;为利用单倍体育种或其它育种途径能否在F_1代稳定光合速率提供依据。材料与方法本试验所用的材料是1976年本院大豆所和生物室的杂交组合共10个。其材料按生育期分类为早熟×中晚熟3个组合、早熟×早熟1个组合、中晚熟×中晚熟3个组合、
In this study, we studied the advantages of F_1 generation photosynthesis rate in parents of different maturity stages of soybean. The purpose is to further clarify the advantages of the first generation of photosynthetic rate and lay a preliminary foundation for carrying out the relationship between F 1 generation and its total generation. It is also provided a basis for using haploid breeding or other breeding ways to stabilize photosynthetic rate in F1 generation. Materials and Methods The materials used in this experiment were 10 combinations of soybean plants and biological chambers in our hospital in 1976. According to the growth period, the materials were classified as early maturity × late maturity, three combinations of early maturity × early maturity, three combinations of middle-late maturity × late maturity,
