달래와 산달래 지방종의 생육 특성 및 유연관계 분석

The major growth characteristics of local strains of Allium monanthum and A. grayi collected in Korea were investigated to obtain the basic information for varietal improvement and cultural practices. There was no difference in days to sprouting among the local strains of A. monanthum. However, the local strains of A. grayi could be classified three groups depend on days to sprouting. There was no difference in days to sprouting of A. grayi as 7 days between in the open field and in shading culture. However, the days to sprouting of A. monanthum at the field was less longer than those at the shading culture. The growth of A. grayi and A. monanthum in the shading culture much better than those in the field but the bulblet production ability was similar. The local strains of A. grayi were distinguished from A. monanthum by the growth characteristics such as bolting, plant height, and leaf width. Among the local strains of A. grayi, there was difference in the number of tillers. Also, among the local strains of A. monanthum, there were difference in plant height, number of tillers, and length of flower stalk. In bulblet production ability of A. grayi and A. monanthum, the bulblet weight and amount of A. monanthum was more heavier than those of A. grayi. Random amplified polymorphic DNAs (RAPDs) were identified in A. monanthum and A. grayi by amplification using 10-mer primers of arbitrary sequence. Cluster analysis for genetic similarity revealed the fairly high variation with between A. monanthum and A. grayi.
