Estimated genetic (additive) effects for root trait QTL measured on random progeny from the Cranbrook/Halberd wheat population evaluated across well-watered and water-deficit environments as described in Botwright Acuña and Wade (2005) and Botwright Acuña et al. (2007)

* Positive additive effects indicate that the Cranbrook allele with ‘a’ the additive effect estimated as one-half the difference in homozygotes carrying either parental allele.
