摘要
为了加强广西地方大豆种质资源的全面普查和抢救性收集,了解种质资源的主要特征特性,进一步为广西大豆种质资源创新和新品种选育提供物质基础,于2015—2019年全面普查与收集广西全区域地方大豆种质资源,2018—2019年采用田间比较鉴定、室内考种、品质检测分析等方法,针对9个质量性状和11个农艺性状及品质性状进行评价鉴定。结果表明:在66个县市共收集到广西地方大豆种质资源382份,其中春大豆45份、夏大豆308份、秋大豆29份。对356份材料的性状分析评价结果显示,该批广西地方大豆种质资源具有较为丰富的遗传多样性。9个质量性状的Simpson多样性指数范围为0.1209~0.7348,其中荚色、脐色、粒型和种皮色的遗传多样性最丰富;11个农艺和品质性状变异系数范围为3.57%~48.50%。筛选出具有粗蛋白含量高、粗脂肪含量高、特大粒及适合加工的优异种质资源黄姚黑豆、马渭秋黄豆、烟墩黄豆1、河池黑豆、朝阳黑大豆、老街黄豆和九月黄等。
To strengthen the comprehensive survey and rescue collection of soybean germplasm resources in Guangxi,understand the main characteristics,and provide the material basis for the innovation of soybean germplasm resources and the breeding of new soybean varieties in Guangxi,we surveyed and collected soybean local germplasms comprehensively in Guangxi from 2015 to 2019.We comprehended the main characteristics of 356 soybean local germplasms with evaluating and identifying 9 qualitative traits and 11 agronomic traits and quality qualitative traits by means of field comparative identification,indoor copying,quality testing and analysis from 2018 to 2019.The results showed that a total of 382 soybean germplasms in Guangxi were collected from 66 counties and cities,including 45 spring soybeans,308 summer soybeans,and 29 autumn soybeans.Those soybean germplasms represented abundant genetic diversity.The Simpson diversity index of the 9 qualitative traits ranged from 0.1209 to 0.7348,and the genetic diversity of pod color,hilum color,seed shape and seed coat color was relatively rich.The variation coefficients of the 11 agronomic and quality traits ranged from 3.57%to 48.50%.As a result high crude protein content,high crude fat and large seed suitable for processing germplasm resources have been screened out,such as Huangyaoheidou,Maweiqiuhuangdou,Yandunhuangdou 1,Hechiheidou,Chaoyangheidadou,Laojiehuangdou and Jiuyuehuang,etc.
