Varietal Characteristics and Genetic Correlations in Two Ecotypes of Garlic

This study was conducted to obtain the basic informations for improvement of garlic varieties. Seven local varieties and twenty belonging to southern and northern ecotypes, respectively were used for this study. Agronomic characters, such as, plant height, leaf length, flower-stalk length, bulb diameter, bulb height, number of clove and bulb weight were determined and phenotypic, genetic and environmental correlations among them were estimated. Variety “Mokpo” in southern ecotype and “Yoeju” in northern seemed to be promising one. These two varieties had smaller number of the second differentiated clove but were comparatively heavier in bulb weight than those of the other varieties tested. Each characters observed in two ecotypes and within a ecotype were very variable. There were the different sign and degree of correlations among some characters in two ecotypes. Bulb weight had positively high correlations with bulb diameter and bulb height.
