摘要
从国内外收集到不同来源大豆 5 6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 ,可作为基础材料应用于栽培和遗传育种的研究上。
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.
