  • Mean values of parents and RILs for grain yield, heading date, and plant height in the 16 field trials carried out in 2004 and 2005 are shown. Environments are listed according to the decreasing mean grain yield values of the RILs. Environments are indicated by acronyms where the first three letters indicate the locations, followed by the water regime indicated with either i (irrigated) or r (rainfed) and the year 04 (2003/2004) or 05 (2004/2005). Location: Itl, Cerignola, Italy; Lbn, Tel Amara, Lebanon; Mrc, Sidi El Aidi, Morocco; Spn1, Granada, Spain; Spn2, Lleida, Spain; Syr, Tel Hadya, Syria; Tns-i04, Koudiat, Tunisia; Tns-r04, Kef, Tunisia.

  • a Mean values of 20 replicated plots per experiment, as in the augmented design experimental scheme adopted in this study.

  • b Mean and range of the best linear unbiased predictor data (field experiments with unreplicated plots).

  • c Days from emergence.
