菜用大豆的农艺及品质性状评价与相关性分析

Relation Analysis and Evaluation on Agronomic and Quality Characters in Vegetable Soybean

对18个菜用大豆品种的农艺性状及品质性状进行了评价和相关分析。结果表明:单株粒数与单株荚数、籽粒产量呈极显著正相关,与生育前期呈显著正相关。百粒重与荚宽呈极显著正相关。籽粒产量与茎粗、单株荚数、单株粒数、地上部产量、生育前期、全生育期呈极显著正相关,蛋白质含量与百粒重呈显著正相关;与单株粒数呈显著负相关。脂肪含量与茎粗、荚长呈显著负相关。

Relations and hereditary potentiality of agronomic and quality characters were studied and analyzed in 18 vegetable soybean cultivars.The results showed that: seeds per plant had a significantly positive correlation with pods and seed yield per plant, as well as with days from emerging to flowering. There was a significantly positive correlation between pod width and.100-seed weight. Seed yield per plan was significantly and positively correlated to stem width,pods and seeds per plant, mass-weight up ground per plant, days from emerging to flowering and days of whole life. Protein content was positively related to 100-seed weight, but negatively to seeds per plant. Fat content was correlative to stem width and pod length significantly and negatively.
