ESTABLISHMENT AND PRIMARY EVALUATION OF QUINCE GERMPLASM COLLECTION FROM VARIOUS REGIONS OF IRAN
Significant variation of quince genotypes and native cultivars is observable in the temperate areas of Iran. In order to use this variation in breeding programs, mainly for fire blight resistance, germplasm was collected and the first Iranian quince germplasm collection was established. Forty-three quince genotypes were selected from Central, Central-North, North, North West and North East regions, from 2004 to 2009. All genotypes were distinguished by morphological and SSR markers. The SSR markers clustered the genotypes to separate groups based on the geographical origin. These groups also demonstrated identical characteristics of the fruits and trees. Quince genotypes had different levels of fire blight susceptibility, but most commercial fruits were observed among quince of central regions that usually were more susceptible to the disease. Quince genotypes from the North with most similarity to the wild ancestors demonstrated low fruit quality, late to very late fruit maturity and high fruit set. These genotypes also clustered as the most dwarfing and showed the lowest level of leaf chlorosis in calcareous soils.
