Fig. 2. Linkage map location of primary, secondary, and tertiary QTL affecting grain yield (GY), heading date (HD), and plant height (PH) in a recurrent selection population of oat. Three linkage groups (O'Donoughue et al., 1995) that were analyzed in detail are shown. Primary QTL regions are defined as those identified using allelic shift, correlation, and single-factor ANOVA data. Secondary QTL were localized using correlation and ANOVA data, and tertiary QTL were identified based on ANOVA alone. An * denotes that the QTL region also was detected in a Kanota x Ogle recombinant inbred line population (Siripoonwiwat et al., 1996). m indicates locus was monomorphic in the recurrent selection population.
