초록

Grass breeding starts with the process of selecting grass with good traits, and this operation consumes a lot of resources. Therefore, there is a need for an efficient screening method. Stolon is a unit for the storage of carbohydrates and vegetative propagation, which enhances grass growth and grass sod. Grass varieties with active production of stolons have excellent traits because they reproduce quickly and have a high density. To select grass with such a trait, the survival rate and the production rate of stolon after transplantation of 72 grass germplasms were investigated. After transplantation, the survival rate ranged from 75% to 100%. The majority of the grass cultivars showed a 100% survival rate. Therefore, the group was divided into two groups: A grass variety showing 100% survival and a grass variety that did not show 100% survival. The grass cultivar group, which showed a 100% survival rate after transplantation, included 61 turf varieties, and the rates of stolon production in these grass varieties ranged from 0 to 100%. In contrast, 10 varieties were included in the grass cultivar group that did not show 100% survival after transplantation. These cultivars had a stolon production rate of 0 to 33%. The results suggest that grass germplasms with a 100% survival rate should be selected.
