Abstract
In order to determinate the self–incompatibility and the most suitable pollinizer for Esfahan commercial quince cultivar, the effects of four different pollinizer treatments ((KM1, PK2, Kvd2, NB4), as self pollination and open pollination) on fruit set and quantitative and qualitative characteristics of commercial quince fruits of Isfahan were studied in a randomized complete block design with 4 replications in quince orchards of Felavarjan region during 3 years. The results of fruit set percentage showed that the mean comparison test had a significant difference between different pollination treatments, except (KVD2, NB4). The maximum fruit set percentage was 23.42 which were related to KM1 genotype, and the minimum percentage was 8.4 which were related to the self pollinated treatment. The mean comparison of self pollinated treatments on fruit weight had a significant difference between KM1 and other treatments. The investigation of quality and quantity characteristics of fruit results showed that there was a significant difference between the Total Soluble Solids (TSS) and firmness. The KM1 genotype (Isfahan sour quince) with 80% of overlap flowering period with 23.42 % of fruit set during three years is chosen and introduced as the best pollinizer for the Isfahan quince cultivar.
