摘　　要：以半无叶类型、普通类型豌豆为试验材料,对卷须性状的特征特性、遗传规律及在育种上的利用进行了研究。结果表明:半无叶类型豌豆品种卷须极其发达,能够在株间相互缠绕,形成棚架结构,显著地提高了品种的抗倒伏能力,同时改善了群体通风透光性能,显著提高了新品种的产量,是豌豆抗倒伏育种的重要原始材料。半无叶类型属单基因质量性状遗传,显隐性完全,卷须基因af和子叶颜色基因i表现连锁,位于1号染色体上,交换值为5.72%。Using semi-leafless pea and common pea,the authors studied tendril character,its inheritance law and how to use it in pea breeding.The results were as follows:Semi-leafless pea had well developed tendrils;They twined with each other and formed an arbor structure.This ideal structure had greatly increased lodging resistance capability,improved canopy's air and light level,and remarkably increased new varieties yield.So,semi-leafless pea was one of the most important materials in lodging resistance breeding.Tendril gene,af,and seed color gene i,in semi-leafless pea was linked on chromosome Ⅰ,and cross-over value was 5.72%.
