Comment	Linked to QTLs for plant height, kernel number per spike, and 1,000-kernel weight in RSLs derived from CNN/CNN (WI3A) (Shah et al., 1999) Sourdille et al., (2000) analyzed QTL in Courtot/CS. Two QTLs for narrow-sense earliness were detected on chromosome 2B in a CS/T. spelta var. duhamelianum KT19-1 RI population. These QTLs were associated with markers Xpsr135-2B and Xabc451-2B. For both QTLs, earliness was conferred by the CS allele (Shindo et al., 2003). QEet.fcu.5AL identified in Xfcp359-5A - Xfcp231-5A interval (R2=0.38), at or near the Q locus in Grandin/BR34. Grandin was the earlier parent (Liu et al., 2005).
