摘要
为更好地分析和利用黑龙江省野生大豆资源,对黑龙江省70份野生大豆进行种质资源的生态性状调查和分析。结果表明:黑龙江省野生大豆的株高、单株荚数、单株粒重的变幅分别为52~240 cm,804~2281荚,1.90~84.85 g,其变异系数比较大,说明野生大豆在株高、单株荚数、单株粒重的性状具有丰富的遗传多样性。百粒重与茎粗和单株粒重极显著正相关,茎宽和单株粒重极显著正相关,说明当茎宽和百粒重增大时,单株粒重有逐渐增大的趋势。黑龙江省野生大豆的蛋白质、油分、蛋脂含量分别为43.36%、13.39%和57.75%,变幅分别为37.48%~53.82%、6.35%~20.97%和51.60%~63.51%。油分含量和蛋脂含量变异系数较小,蛋白质含量变异系数较大,说明蛋白质含量变化较大,多样性丰富。黑龙江省野生大豆在单株粒重、单株荚数、株高等生态性状的变异系数较大,可以利用野生大豆基因具有丰富的遗传多样性来改善栽培大豆的特性。蛋白质含量最高为53.82%,为提高栽培大豆蛋白质含量提供优质基因。
In order to better analyze and utilization of wild soybean resources in Heilongjiang Province,in this study,ecological characteristics of 70 wild soybean germplasm resources were investigated and analyzed in Heilongjiang Province.The results showed that the amplitudes of the plant height,pods number per plant,grain weight per plant of wild soybeans were 52-240 cm,804-2281 pods,1.9-84.85 g in Heilongjiang Province,respectively.The height,pods number per plant,grain weight per plant of the wild soybeans have the large genetic diversity because of great coefficient of variation.Further analysis showed that there was an extremely significant positive correlation among 100-seed weight,stem diameter,stem width and individual grain weight,indicating that when stem width and 100-seed weight increased,individual grain weight increase gradually.The contents of protein,oil and the total content of protein and oil of wild soybean in Heilongjiang Province were 43.36%,13.39%and 57.75%,respectively,and the amplitudes were 37.48%-53.82%,6.35%-20.97%and 51.60%-63.51%,respectively.The coefficients of variation of oil and the total content of protein and oil were small,but the coefficients of variation of protein content were large,which indicated that the protein content changed greatly and the diversity was rich.In conclusion,ecological characteristics of grain weight per plant,pods number per plant,the plant height of wild soybeans have great coefficient of variation.The rich genetic diversity of wild soybean genes can be used to improve the characteristics of cultivated soybean.The highest protein content was 53.82%,which provided high quality genes for improving the protein content of cultivated soybean.
