摘要:

种质资源的鉴定和评价是充分利用优异基因加速品种改良的第一步。为探究菜用大豆种质资源农艺性状的遗传多样性,构建食味品质评价体系,本文以在全国范围内收集的379份菜用大豆种质资源为材料,对25个农艺性状进行了2年的表型调查,并对其多样性进行了分析和评价。结果表明,25个农艺性状的遗传变异十分丰富,除3个质量性状之外的22个数量性状多样性指数的变化范围在1.40~2.06。在8个核心种质聚类方法中,最长距离法构建的核心种质代表性最好,涵盖了原始种质的所有变异范围。利用核心种质群体对影响菜用大豆食味品质的7个关键理化指标进行了测定,并对6个感官维度进行人工评价,通过相关性分析和多元线性回归分析,明确了可溶性总糖、脂肪和总游离氨基酸含量是影响食味品质的3个关键理化指标,甜味、糯性和硬度3个维度可解释整体喜好变化率的68.2%。本研究结果可为提高菜用大豆种质资源的评价与利用效率,加快高产、优质菜用大豆品种的选育提供参考。

Abstract:

The identification and evaluation of germplasm resources is the first step to make full use of elite genes to accelerate the improvement of varieties. In order to explore the genetic diversity of agronomic traits and build an evaluation system for taste quality, 379 vegetable soybean lines widely collected throughout the country were adopted and 25 agronomic traits were investigated in 2 years. The diversity of this whole collection was analyzed and evaluated based on phenotypic data. The results showed that the 25 agronomic traits of the panel contained abundant genetic variation. Except for three quality traits, the diversity index of 22 quantitative traits varied from 1.40 to 2.06. Among the 8 methods of core gemplasm clustering, the core gemplasm constructed by the longest distance method was the most representative, covering all the traits variations of the original gemplasm. Seven key physical and chemical indexes affecting the taste quality of vegetable soybean and six sensory latitudes were determined in this core collection. A multiple linear regression model for vegetable soybean quality was constructed. It was clear that soluble total sugar, oil and total free amino acid contents were three key physical and chemical indexes affecting the taste quality. The three dimensions of sweetness, waxiness and hardness could explain 68.2% of the overall preference change rate. The results of this study are expected to provide a reference for improving the evaluation and utilization efficiency of vegetable soybean germplasm resources and accelerating the cultivation of high-yield and high-quality vegetable soybean varieties.
