Abstract: 

Loliul1l species have different characteristics. Interspecific hybridization would facilitate the integration of valuable characteristics into one variety. In this regard several interspecific hybrid plants were produced between Loliul1l perenne and L. rigidum through embryo rescue. For verification of hybridization four interspecific hybrids along with their parents were investigated for their karyotypic characteristics. There was a vast variability in chromosome number in the hybrids. To detect the differences between the genotypes and their chromosomes the data were analyzed in a factorial statistical model with the base design of completely randomized design. The differences between the numbers of chromosomes in the hybrids indicated the incompatibility between the genomes of the two parents as well as confirming the hybridization. On the other hand, this phenomenon is common in L. rigidul1l which was used as the male parent. It seems this phenomenon was a heritage from the male parent. A number of parameters were estimated to investigate the karyotypic symmetric of the genotypes whose TF% indicated that one of the parents (P1) has the most asymmetric karyotype and one of the hybrid genotypes (L3) has the most symmetric karyotype.
