Elouafi et al. (HDT-135-255) identified a QTL with a large effect on yellow pigment in the distal region of the long arm of chromosome 7B in a cross between the cultivated durum variety Omrabi5 and T. dicoccoides. Microsatellites Xgwm344-7B and Xgwm63e explained 53% and 13% of the variation in yellow pigment, respectively.
Hessler et al. (CRS-42-1695) identified a minor QTL for yellow pigment in a Jennah Khetifa x Cham 1 cross with Xbcd926 explaining 10.4% of the variation.
An STS developed from the AFLP marker Xwua26.4 on 7AL explains 60% of the variation in grain yellow pigment content in a Schomburgk x Yaralinka population.
Xpsr680, Xwmc25a, and SksuB8 explain 10%, 12%, and 17% of the variation in grain yellow pigment content in a CD87 x Katepwa population, respectively.
A gene distal to Xwmc346 explains 27% of the variation in grain yellow pigment content in a Sunco x Tasman population.
