摘要Elymus fedtschenkoi Tzvel.是广泛分布在亚洲中部的多年生牧草。它既是重要的饲料牧草 ，也有可观的植被利用价值。经形态和生殖鉴定发现该种具有丛生性和自花授粉结实习性。 经细胞学观察，发现它的花粉母细胞减数分裂中期I形成14个二价体(表1)，其中90%以上是 环状二价体(图版II，A)，说明E.fedtschenkoi是异源四倍体，2n=28。已经成功地把它跟另 外两个种杂...
摘要本研究以Elymus pendulinus (Nevski) Tzvelev(2n=4x=28,SSYY)、E.shandongensis B.Sal omon(2n=4x=28,SSYY)与普通小麦(Triticum aestivum L.;2n=6x=42,AABBDD)进行了属间远 缘杂交。通过对杂种胚的离体培养，两个组合均产生了杂种F1植株。杂种F1为多年生，植株 生长旺盛；形态上介于...
