Abstract

Flour yield quantitative trait loci (QTLs) were identified in 3 Australian doubled haploid populations, Sunco x Tasman, CD87 x Katepwa, and Cranbrook x Halberd. Trial data from 3 to 4 sites or years were available for each population. QTLs were identified on chromosomes 2BS, 4B, 5AL, and 6BL in the Sunco x Tasman population, on chromosomes 4B, 5AS, and 6DL in the CD87 x Katepwa population, and on chromosomes 4DS, 5DS and 7AS in the Cranbrook x Halbred population. In the Sunco x Tasman cross the highest genetic variance was detected with the QTL on chromosome 2B (31.3%), in the CD87 x Katepwa cross with the QTL on chromosome 4B (23.8%), and in the Crnabrook x Halbred cross with the QTL on chromosome 5D (18%). Only one QTL occurred in a similar location in more than one population, indicating the complexity of the flour yield character across different backgrounds.
