大豆抗裂荚基因pdh1在育成品种中的分布
Distribution of pod shattering resistance gene pdh1 in cultivated soybean varieties
摘要
Abstract
Soybean pod shattering is a significant challenge to soybean production.The pdh1 gene is one of the main genes controlling soybean pod shattering resistance,and is greatly influenced by environments,which limits its utilization in breeding.To explore the feasibility of anti-pod shattering genes in breeding and reduce soybean yield loss,this study used anti-pod-shattering gene pdh1 as a marker to analyze 348 varieties cultivated between 1929 and 2021.Results revealed that pod dehiscence is highly related to the carrying of pdh1.255 out of 348 mate-rials carried pdh1 gene,accounting for 73.3%of the total.The distribution of pdh1 gene has obvious regional varia-tions:80%-85%of varieties from Northeast region had pdh1,and 68%-72.1%of varieties from Huanghuai har-bored pdh1,while only 30%-36.3%varieties from Southern China possessed pdh1.The low proportion of varieties from Southern China with pdh1 might be related to high humidity climate in these areas.Therefore,using molecular marker detection as the primary method for screening anti-shattering pods in southern soybeans might overcome en-vironmental influences and improve selection efficiency.关键词
