Mediterranean region and its production is largely influenced by environmental stresses, such as drought, salinity, heat and
nutrient deficiency. The objective of this study was to dissect quantitative trait loci (QTL) controlling grain yield, yield
components and drought tolerance in durum. A molecular genetic linkage map for F2 durum mapping population derived
from an intraspecific cross between Baniswif-1 x Sohag-2 was constructed using 114 DNA markers (9 SSRs, 14 SCoTs, 90
AFLPs and 1 RAPDs) distributed over the 14 linkage groups and spanning 2040.9 cM of the durum wheat genome. The
size of linkage groups varied greatly from 6.8cM for LG11 to 317.5cM for LG4 with an average length of 145.8cM. Based
on the used anchor SSR markers, only eight linkage groups were assigned to chromosomes, where LG1, LG3, LG5, LG6,
LG7, LG9, LG13 and LG14 were assigned to chromosomes 1B, 3B, 5B, 6A, 6B, 7A, 3A and 2B, respectively. Single point
analysis was used to identify genomic regions controlling e
