摘　　要：为了保障温带地区优质植物蛋白的供给,加快选育高蛋白的蚕豆品种,对蚕豆蛋白含量遗传规律进行分析。以高蛋白含量材料‘羊眼豆’(H0001860)为父本,低蛋白含量材料‘大粒豆’(H0004518)为母本构建F2群体,利用杜马斯燃烧定氮法和主基因+多基因混合模型对蚕豆蛋白含量进行遗传分析。蚕豆蛋白含量的最优遗传模型为2MG-EA(2对等加性主基因)模型,2对等加性主基因模型的加性效应值da(d)为1.7238,加性效应表现为正向效应。主基因的遗传方差为2.4817,主基因遗传率较高(62.0286%)。蚕豆蛋白含量的最优遗传模型为2对等加性主基因模型,蚕豆蛋白含量的遗传改良应该在早期分离世代进行。In order to guarantee the supply of high-quality plant protein in temperate regions and accelerate the selection and breeding of high-protein faba bean varieties,the genetic law of protein content of faba bean was analyzed.An F2 population was constructed with the high-protein content material'Sheep's Eye Bean'(H0001860)as the father and the low-protein content material'Big Grain Bean'(H0004518)as the mother,and the genetic analysis of faba bean protein content was carried out by using the Dumas combustion nitrogen determination method and the main gene+multigene hybrid model.The optimal genetic model for protein content of faba bean was 2MG-EA(2 pairs of equal additive principal genes)model,and the additive effect value da(d)of the 2 pairs of equal additive principal genes model was 1.7238,and the additive effect showed a positive effect.The genetic variance of the main gene was 2.4817,and the heritability of the main gene was high(62.0286%).The optimum genetic model for protein content of faba bean is 2 pairs of equal additive main gene model,and genetic improvement of protein content of faba bean should be carried out in early segregating generations.
