Quantitative trait locus mapping of some agro morphological traits in einkorn wheat

The purpose of this study was to map quantitative trait locus for some agro-morphological traits of einkorn wheat (Triticum monococcum spp, monococcum). To this end, parents and 151 F8 recombinant inbred lines (RILs) obtained through single seed descent from cross ID1623 and MONLIS were sown according to randomized blocks design with three replications during the growing seasons of 2017-2018 and 2018-2019 in Adana and Konya locations. Of the 23.981 SilicoDArT, 27.221 SNP, and 200 SSR markers, a total of 787 SilicoDArT, 865 SNP, and 16 SSR markers were used for map construction after removing markers, which duplicated, did not polymorphic between parents and with minor allele frequency (<0.05), from raw data. As a result of the study, the resulting genetic linkage map had 1668 SilicoDArT, SNP and SSR markers in 741 loci mapped onto seven linkage groups and covered 1158.54 cM with a mean interval distance of 1.59 cM between the locus. Quantitative trait locus (QTL) analysis for agro-morphological traits by the Multiple QTL Mapping method identified 76 QTL on all seven chromosomes. On the chromosomes 1A, 2A, 5A, and 7A, a total of 13 stable QTLs detected at least in two environments were related to days to heading (3), plant height (2), peduncle length, spike length (2), grain number per spike (2) grain yield per spike (2) and thousand kernel weight. From the results of study, it was concluded that the detected QTL regions on the resulting genetic map could be used in marker-assisted breeding studies in einkorn and other wheat species after verification of them.
