DETERMINATION OF SELF-(IN) COMPATIBILITY USING MOLECULAR MARKERS OF SOME APRICOT CULTIVARS WHICH CULTIVATED IN TURKEY

Abstract

In fruit trees, gametophytic self-incompatibility is one of the major problem because of preventing self-fertilization controlled by a single locus with some allelic variants. Among the fruits, apricots also show self-incompatibility especially originated from Middle-Asian and Iranian-Caucasian. In present study, it was determined self-compatible/incompatible of some apricot cultivars which cultivated in Turkey. 17 Turkish and 42 foreign apricot cultivars were used in this study. Analyses were carried out using three primer pairs (SRc-R-SRc-F, EM-PC2consFD / EM-PC3consRD and AprFBC8). A total 5 S-RNase alleles (S2, S3, S6, S9 and S11) were determined in the 11 new Turkish cultivated apricots and a total 8 (S3, S7, S8, S9, S11, S12, S13 and SC) were determined in old Turkish apricot cultivars. A total 11 S-RNase alleles (S2, S3, S4, S6, S7, S8, S9, S11, S12, S19 and SC) were determined in foreign 42 apricot cultivars. It was determined self (in)compatibility alleles of 11 new Turkish and 38 foreign apricot cultivars first time with this study. These results can be used for plantation new orchards and breeding programs. Also, pollinator cultivars should be considered for plantation new orchards for these self-incompatible cultivars because of some Turkish and foreign apricot are mostly self-incompatible.
