摘要
对草地早熟禾品种间及其与变种扁秆早熟禾之间进行了人工去雄杂交 ,对各杂交组合的后代进行了杂种优势预测 ,结果表明品种间杂交中莫诺波利草地早熟禾和瓦巴斯草地早熟禾的杂种在产草量方面有较强的优势 。
Artificial emasculation and heterosis forecast were applied in Poa pratensis and Poa pratensis var. anceps. The result showed that in interaspecific hybridization, the hybrid of Poa pratensis cv. Monoploy and Poa pratensis cv. Wabash had higher heterosis, while in interspecific hybridization, the hybrid of Poa pratensis var. anceps and Poa pratensis cv. Storpy had a high heterosis.
