Abstract

In the study, B28 and Kunduru-1149 durum wheat genotypes were crossed as reciprocal in 2012-2013 cropping season. 13 (B28/Kunduru-1149 and Kunduru-1149/B28) reciprocal crosses were obtained and were used as materials at F5 stage. The cross combinations and the parents were screened with 10 DNA markers to determine alleles of gluten strength (Bx7OE), Yellow rust (Sun104, Xgwm18, Xwgp115 and Xgwm47), stem rust (Sun209 and Sun479), high protein ratio (UHW89), powdery mildew (Xgwm66) and leaf rust (Xgwm130). In the study, the average polymorphism information content (PIC) was calculated as 0.98 and the lowest PIC value was obtained from Xwgp115 marker with 0.96, while the rest of the markers had 0.99 PIC values. Stem rust resistance allele Sr49 was detected in B28/Kunduru-1149_F5_4 (Sun479) and B28/Kunduru-1149_F5_1 (Sun209) genotypes. One of the yellow rust resistance alleles Yr15 (Xgwm18) was detected in B28/Kunduru-1149_F5_2 and B28/Kunduru-1149_F5_3 genotypes, while Yr51 (Sun104) was identified in B28/Kunduru-1149_F5_3, B28/Kunduru-1149_F5_6, B28/Kunduru-1149_F5_7, Kunduru-1149/B28_F5_2 and Kunduru-1149/B28_F5_6 genotypes. A dendrogram was created to determine kinship of the individuals with the parents. The highest genetic similarity was observed between B28 / Kunduru-1149_F5_6 and Kunduru-1149 / B28_F5_2 genotypes with 0.714, while the most diverse ones were Kunduru-1149 and B28/Kunduru_F5_7 with 0.10.
