Fig. 2. QTL locations for the tocopherols in the per se and testcross progenies for chromosomes 1 and 5. QTL positions for 200 (W64a x A632) F_2:3 per se progenies and the 185 (W64a A632 F_2:3) x AE335 testcross progenies shown relative to the location on the (W64a x A632) F_2:3 per se map. Significant in the per se progenies. Significant in the testcross progenies. Significant by single factor analysis of variance; Estimated distance between markers when phi037 is forced onto the final map.
