| 摘 要： | 从国内外收集到不同来源大豆56份在低钾土壤上种植，发现不同品种（系）大豆对低钾的耐性上存在着较大的差异性。通过研究耐性与产量的关系。将这些品种（系）分为高产敏感型，高产不敏感型，低产敏感型和低产不敏感型4种类型。其中高产不敏感型与低产不敏感型具有钾高效基因。可作为基因材料应用于栽培和遗传育种的研究上。

| Abstract: | Fifty-six soybeans collected from internal and external nations were planted on the low-potassium soil. The differences of different soybean resistant to low-potassium were shown. According to the relations of resistance and yields, those soybeans were classified into 4 types: high-yield and sensitivity, high-yield and non-sensitivity, low-yield and sensitivity and low-yield and non-sensitivity. High-yield and non-sensitivity and low-yield and non-sensitivity had potassium high efficiency gene and could be as the basic materials for culture and breeding. |
