Xwmc525 was the only locus displaying codominant gene action and the stutter observed was consistent with the description of this locus in GrainGenes.
These are consistent with the segregation of a single codominant gene.
This is consistent with control of the fatuoid character by a single codominant gene.
This clearly indicates the inadequacy of a model based on a single codominant gene, as reflected by significant deviations from the 1:2:1 ratio (i.
Given that previous studies (Huskins, 1946; Coffman, 1964) had found that variation in the fatuoid character in hulled oat germplasm could be explained by the segregation of one codominant gene, we investigated the possibility that the hulled progeny of the NO753-2/Marion and NO753-2A/Marion crosses would satisfy single-gene models better than the naked-grained progeny of the same crosses.
05, respectively) approximated the expected 1:2:1 segregation ratio for a codominant gene (Table 2).
With respect to resistance to Mi the following comments can be made: (i) the major QTL on LG-O (G248A-1) explained 31% of the variation in gall number and acted additively, (ii) gall number data when classified as a single codominant gene was 27 cM from the QTL, and (iii) the level of resistance observed in Forrest, 26 galls, (Luzzi et al.
They may also be applied to backcross programs in which dominant or codominant genes are to be transferred from the nonrecurrent to the recurrent parent.
