| 110 F9 recombinant inbred lines (RILs) derived by single-seed descent from the cross ICD-MN91-0012 between Jennah Khetifa (Tamgurt) and Cham1 were used. The CIMMYT/ICARDA durum-breeding program for Mediterranean dryland has developed the population in 1991 at the Tel Hadya research station (Aleppo province, Syria). |
| Jennah Khetifa (JK, aka. Tamgurt), a landrace variety, is characterized by moderate resistance to drought and shows specific adaptation to North African continental dryland. Cham 1 shows high osmotic adjustment and grown for commercial production in several countries of the Mediterranean basin. |
| Linkage analysis and map construction were performed by using Map Manager QTX14 (Manly and Cudmore 1997) using the Haldane function (Haldane 1919) to convert the recombination frequencies to centiMorgans (cM). |
