以二倍体萹蓄豆与四倍体肇东苜蓿的诱发突变体作杂交亲本,可获得属间远缘杂交成功。杂种F_1表现了两亲本的中间型形态特征。有孕性的杂种为异源四倍体,属于远缘有性杂种。
Diploid 萹 bean and tetraploid Zhaodong alfalfa induced mutants as hybrid parents, can be obtained distantly cross hybridization success. Hybrid F1 showed the intermediate morphological characteristics of the two parents. The gestational hybrids are allotetraploid and belong to distant sexual hybrids.
