Abstract
For the conservation of the population of Malus sieboldii around Konbukuro Pond in Kashiwa city, the genetic structure and the morphological diversity of 7 populations of Kanto district was studied. Based on the allozyme analysis, Expected heterozygosity of total populations was high as 0.22, compared with other dicotyledon species. That of Konbukuro population was 0.247 and the highest among the studied popultations. In the dendrogram constructed based on denetic distance, the population of Konbukuro was classified in the east Kanto group. However, the morphological property of flower of Konbukuro population had unique characteristics irrelevant to geographic group derived from genetic study. Consequently, the population of Malus sieboldii around Konbukuro Pond has not genetically deteriorated, and it is appropriate to propagate saplings from the native population of Konbukuro to restore this population.
