Product for cadmium-tolerant vegetable variety classification

Abstract

The invention discloses a product for cadmium-tolerant vegetable variety classification. In the specific embodiment of the invention, the abundance difference of the g_MND1 in different clustering groups is found by extracting the soil DNA of the cadmium-tolerant peppers in different clustering groups and sequencing, so a new thought is provided for cadmium-tolerant vegetable variety classification. The invention further provides a method for screening the substance for improving the cadmium tolerance of the vegetables.
