Abstract

Male sterility in Pennisetum americanum (L.) Leeke, inbred line IP 482, was found to be inherited as a monofactorial recessive phenotype. Homozygosity for the gene designated ms 2, produced in addition to pollen abortion, plasmodial tapetum, plasmodial pollen mother cells, delayed and asynchronous meiotic development, desynapsis and blockage of meiosis. Plasmodial PMCs resulted from the fusion of PMCs at pachytene.

摘要

在美洲狼尾草（Pennisetum americanum（L.）Leeke）自交系 IP 482 中发现雄性不育是一种单因子隐性表型，是由基因 ms 2 纯合引起的，除了花粉败育外，还会导致绒毡层原生质体、原生质体花粉母细胞、减数分裂延迟和不同步、联会和减数分裂阻断。原生质体 PMCs 是由粗线期 PMCs 融合形成的。
