摘要：
Disclosed is a Lolium multiflorum diploid plant or parts thereof which segregates for levels of pollen sterility and where upon using the Lolium as the maternal parent in an interspecific hybridization with a Festuca species, being utilized as the paternal parent, confers to the resultant sterile F1 interspecific hybrids the ability to produce some seed via parthenogenesis that also possess a viable embryo, wherein said seeds which possess a viable embryo, may develop into F2 generation plants at least some of which are dihaploid homozygous Festuca species comprising a karyotype exhibiting a balanced genome of Festuca chromosomes equivalent to the chromosome number of said Festuca paternal parent and no Lolium chromosomes.
