Carry out the embodiment that the present invention will be described in detail below in conjunction with accompanying drawings and embodiments, thereby how the present invention is applied
Technological means solves technical problem and reaches the realization process of technical effect to fully understand and implement.
Currently, the evaluation method of Soybean Germplasm is just for certain single index or a few index, such as only with yield
Index is evaluated, and while screening obtains high yield germplasm, but has ignored low output but the germplasm with other merits
Material cannot be fully used so as to cause germ plasm resource in rearing new variety, and the hereditary basis of Soybean Cultivars Released becomes
It is very unfavorable to breeder's Cultivars in narrow.Therefore, the method only a certain single index evaluated, it is difficult to objective,
Accurately evaluate soybean germplasm, need that integration capability is stronger, the faster method of speed, to multiple indexs of multiple kinds simultaneously into
Row evaluation, classification utilization is carried out by germ plasm resource by its advantage character.
Fig. 1 is the flow chart of the Soybean Germplasm evaluation method of the embodiment of the present invention.If Fig. 1 shows, the present embodiment it is big
Beans germplasm resource evaluation method includes the following contents.
