At present, there are many kinds of soybeans grown in China. They include wolfberry soybeans, soybeans, green beans, evergreen beans, white hair tips, early soybeans, soybeans, yellow pods, green beans, and flower beans. These soybean crop plants all have a The common characteristic is that the dry matter produced is mostly derived from photosynthesis, which means that photosynthesis is an important factor in determining soybean yield. Therefore, the use of photosynthesis instrument to study the high photosynthetic efficiency of soybean breeding aims at analyzing the germplasm resources of soybean. The relationship between single-leaf photosynthetic efficiency, agronomic shape, and yield was selected to screen out some high-efficiency planting materials so as to establish a high-efficiency breeding system and provide basis for high photosynthetic efficiency breeding.

In the process of research, the photosynthetic rate of plants was measured using a photosynthesis instrument. It is a agricultural breeding measuring instrument applied with the development of science and technology in recent years. It has the characteristics of simple operation, convenient carrying, and accurate measurement results. Widely used in the determination of photosynthetic rate of various types of plants. The photosynthetic apparatus was used in the field bioassay during the soybean harvesting period, and the photosynthetic rate difference between different materials was studied.
The results showed that the photosynthetic rate of single leaf had a certain correlation with grain weight per plant and total number of pods per plant in soybeans with similar growth period, and those with high leaf photosynthetic rate had grain yield. It is also high, which shows that there is a positive correlation between photosynthetic rate and yield. In the course of the experiment, it also verified that the application of photosynthesis instrument in high photosynthetic efficiency soybean breeding is feasible. In photosynthetic high efficiency breeding, the photosynthetic rate of single leaves in the growing stage of soybean is measured by a photosynthesis instrument, and some high light efficiency germplasms are initially screened. The use of these high light efficiency germplasm as a parent can be used, or the elimination selection can be directly accelerated. The breeding process has a certain significance in high photosynthetic efficiency breeding.
