与二倍体对照相比，同源四倍体材料的花粉育性、结实率均不同程度下降，尤其低代材料的花粉育性59。

Compared with diploid control, the pollen fertility and seed set of autotetraploid declined dramatically, especially in preliminary generations, and they were only 59.

饲用黑麦和冬小麦杂交组合结实率（10.21%）低，亲和性差，但籽粒饱满度（41.20%）相对较高，远缘杂交结实率与籽粒饱满度之间相关关系不明显。

The crosses from forage rye and winter wheat were lower in seed setting rate(10.21%)and poor in compatibility, but the plumpness were higher(41.20%).
