Analysis of clonal variations in cultivated quince (Cydonia oblonga‘Kalecik’) based on fruit characteristics and SSR markers

Abstract

This study assessed uniformity within a quince cultivar (Cydonia oblonga 'Kalecik'). The fruit traits of six different clones within 'Kalecik' quince plantations were evaluated over a 2-year period. Additionally, clones were genetically analysed at seven SSR (microsatellite) loci (CH01f02, CHOlhOl, CH01h10, CH01d08,CH02b12,KA16, and KA14). According to important fruit characteristics, clone 6 was selected as the best in both years. This clone had a lower fruit skin colour hue value (92.7-88.5°), higher soluble solid content (15.6-16.5%), better H08051; Online publication date

Characterization of Anatolian traditional quince cultivars, based on microsatellite markers

“…In our study, the H O values were found to be high for CH01F02, CH01H10, CH02B12, KA4b, KA16, and CH04E03 loci (Table 2), and previous reports also found relatively high H O values for CH01F02, CH02B12, and KA16 (Dumanoğlu et al, 2009) and for CH01H10 (Dumanoğlu et al, 2009;Bassil et al, 2011) in some quince cultivars.…”

“…SSR markers developed from other Prunus species (apple and pear) were used successfully for the genetic characterization of quince cultivars in this study, as has been observed previously (Dumanoğlu et al, 2009;Halász et al, 2009;Bassil et al, 2011).…”

“…from Turkey have been genetically characterized with SSR markers and other molecular markers (Ayanoğlu et al, 2007;Akpınar et al, 2010;Bayazit et al, 2011;Yilmaz et al, 2011), no SSR-based genetic identification study has been conducted on Turkish quince germplasm without clonal variation study of Kalecik quince cultivar by Dumanoğlu et al (2009). The findings of this study will…”

“…In addition, Dumanoğlu et al (2009) found that in addition to CH01F02, CH01H10, CH02B12, and CH01D08, the loci KA14 and KA16 showed a clear distinction in clones analyzed, and clonal differences emerged, indicating that these loci are indeed effective in quince cultivar identification.…”

“…Many researchers have used SSR and inter-simple sequence repeat (ISSR) markers to identify quince populations and clonal variation (Dumanoğlu et al, 2009;Bassil et al, 2011;Ganopoulos et al, 2011). Although pomological data have been described for some native Turkish quince accessions (Küden et al, 2009), quince genetic germplasm has not been fully identified yet, especially using SSR markers.…”
