Özet
Durum wheat (Triticum turgidum ssp. durum Desf.) is a traditional Mediterranean crop and widely produced in Turkey. This study was carried out to compare the allelic variation and agronomic characteristics of durum wheat genotypes during 2015-2016 and 2016-2017 in a randomized complete block design with four replications. A total of 14 durum wheat genotypes including twelve durum wheat cultivars (Guney Yildizi, Sari Barak, Saricanak 98, Zenit, Burgos, Saragolla, Cesare, Zuhre, Levante, Ecem, Svevo, Dumlupinar), one old variety (Kundum-1149) and a landrace (Karakilcik) were used as plant materials. Allelic variations of the 14 dumm wheat genotypes were determined using 11 DNA markers. According to the results, genotypes were found variable for all investigated traits except grain filling period (GFP), years were found different for all traits except gluten content (GC) and yellowness (B) and genotypexyear interaction (GxY) varied for plant height (PH), vegetative period (VP), days to maturity (DM), grain number per spike (GNS), test weight (TW), thousand kernel weight (TKW), grain yield (GY) and GC. The highest grain yield was obtained from Cesare cultivar over two year data with 5568 kg ha(-1) and followed by Burgos and Svevo cultivars with 5080 kg ha(-1) and 5027 kg ha(-1), respectively. Protein ratio (PR) of the genotypes ranged between 10% to 14.8% and Cesare and Karalulcik had the highest PR. According to the dendrogram, Burgos and Karalulcik genotypes were found similar in terms of the alleles investigated in the study with 86%. San Barak and Dumlupmar genotypes were found the most diverse compared to the other genotypes. Eleven allele specific DNA markers interrogated in 20 loci and the allele number per marker was found as 1.8. The average polymorphism information content (PIC) was identified as 72.5%. Cesare cultivar produced bands for eight allele specific markers and Zenit cultivar was the only cultivar that produced allele for Xgwm18 marker. The findings of this study may shed light to breeding programs with field and laboratory performance of these genotypes. (C) 2019 Friends Science Publishers
