用 Trifolium hratense (2n=14)×T.diffusum (2n=16)和 T.hratense(2n=28)×T.diffusum(2n=32)得到了种间杂种。在二倍体水平上杂交保证了异花授粉和回交情况下有生命力种子和不育植株(2n=15)的形成。这些类型的四倍体杂交时得到了具有中间生物学和经济特征以及在自花授粉、异花授粉和回交情况下具有
Interspecific hybrids were obtained with Trifolium hratense (2n = 14) × T.diffusum (2n = 16) and T.hratense (2n = 28) × T.diffusum (2n = 32) Hybridization at the diploid level ensures the formation of viable seeds and sterile plants (2n = 15) in the case of cross-pollination and backcrossing. These types of tetraploids hybridize with intermediate biological and economic characteristics as well as in the case of self-pollination, cross-pollination and backcrossing
