Problems solved by technology

Due to geographical restrictions, the former method is not easy to be used frequently by most breeders, and the identification results will be inaccurate due to differences in growth period and other characteristics; the latter method will also be affected by soil fertility, light and other conditions, resulting in Identification results are inaccurate

[0016] Multi-point Drought Resistance Identification Test of Soybean Strains in Huanghuaihai Region

[0017] 1. Identification conditions

[0018] The drought resistance appraisal of this experiment was carried out in Fenyang City, Shanxi Province, the experimental farm of Economic Crops Research Institute of Shanxi Academy of Agricultural Sciences. The identification test is spring sowing, the local annual frost-free period is 175 days, the altitude is 747.7 meters, the north latitude is 37°15', and the east longitude is 111°47'.

Abstract

The invention discloses an identification method for drought resistance of soybean. The identification method comprises the following steps: planting to-be-identified soybeans in a field, after final singling of seedlings of the soybeans, laying manufactured water collection grooves among rows of the soybeans, after the soybeans are mature, harvesting the to-be-identified soybean plants, carrying out indoor seed testing, and identifying the drought resistance of the soybeans according to seed testing results. According to the invention, the problem of the demand for allopatric identification of the drought resistance of the soybeans in an exceptionally drought area is solved; and the method can achieve the purpose of drought treatment through rainfall collection via the water collection grooves, facilitates one-off identification of a large number of materials, and can reduce the error of identification of the drought resistance.

Description

technical field [0001] The invention relates to a method for identifying drought resistance of crops, in particular to a method for identifying drought resistance of soybeans. Background technique [0002] Drought is one of the main factors affecting crop growth. Breeding drought-resistant varieties is the main breeding goal of breeders. Through the identification of drought resistance, it is the basic work of breeding research to discover excellent drought-resistant breeding resources. At present, there are two main methods for drought resistance identification of soybeans. One is to conduct drought resistance identification in a special drought location (such as Dunhuang City, Gansu Province), and the other is to use dry sheds, potted plants and other means to conduct drought resistance identification. Due to geographical restrictions, the former method is not easy to be used frequently by most breeders, and the identification results will be inaccurate due to difference...
