Abstract
In this study, 241 zoysiagrasses (Zoysia spp.) accessions naturally growing in South Korea were collected in order to investigate the seed morphological traits. One of the goals of this study was to identify the morphological characteristics and variations of zoysiagrass seed. For the 241 zoysiagrasses accessions collected, a total of 41% (99 accessions) was interspecific hybrid zoysia, which showed various types of seed variations different from zoysiagrass species. Most of these hybrids zoysiagrasses were classified into Z. sinica type and Z. japonica type. Group I and II included Z. sinica type, this group showed 30.1 and 17.5 in number of seed per spike and 4.6 and 5.2 mm in seed length. Group III and IV included Z. japonica type, this group showed 59.2 and 45.8 in number of seed per spike and 3.3 and 3.4 mm in seed length. There is a need for additional research on growth characteristics and the molecular level for the interspecific hybridization which confirmed that genetic variation from level of gene flow between the species.
