摘要
采用 6个同源四倍体高粱品系及其与约翰逊草的种间杂种为材料 ,分析了种间杂种的生物学特征、饲用价值、杂优表现及其稳定性。发现杂种F1在生物产量上表现了巨大优势 (70 0 %~ 90 0 % ) ,F1~F3在生物产量上优势相对固定 ,比双亲有显著提高 。
Interspecific hybrids between autotetraploid Sorghum (S.bicolor L. Moench) and Johnsongrass (S. halepense L. Pers) were produced. The morphological characteristics, heterosis and the forage value of interspecific hybrid were performed. The results showed that hybrids exhibited great heterosis on growth potential and biomass (70.0%~90.0%). No evident differences were observed from F 1 to F 3 hybrid with high biomass compared to parents, and the low generation had high forage quality.
