This study investigated a clonal variations in sprouting times of Allium victorialis L. collected from 28 habitats around Hokkaido, Japan, propagated vegetatively and grown in Sapporo. For comparing clones, plant height is a useful index of sprouting time. Results of a two- year survey from 2000 to 2001 Indicated that the sprouting time of Allium victorialis L. was a stable genetic trait and the clones were divided into 3 groups based on the results. Random amplified polymorphic DNA (RAPD) analysis was successfully performed on these clones utilizing 20 different primers. The clones were divided into 6 groups according to result from RAPD analysis. There was no relationship between the classification based on sprouting time and that based on RAPD analysis. However, both results indicated that genetic distance between 2 clones originating in a same region was short. The difference in sprouting times among these clones seems to be available for breeding new cultivars of Allium victorialis L.
