  • Roegneria grandis was hybridized withR. ciliaris var.japonensis (2n = 28, SSYY),Elymus caninus (2n = 28, SSHH), andPseudoroegneria spicata (2n = 28, SSSS). Chromosome pairing was studied in parents and hybrids. It is concluded from this study that: (i)R. grandis is an allotetraploid species and contains the basic genomes S and Y: (ii) a certain degree of homoeology exists between the S and Y genomes of the species studied.
