Abstract:
Flour yield quantitative trait loci (QTLs) were identified in 3 Australian doubled haploid populations, Sunco _ Tasman, CD87 _ Katepwa, and Cranbrook _ 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 _ Tasman population, on chromosomes 4B, 5AS, and 6DL in the CD87 _ Katepwa population, and on chromosomes 4DS, 5DS, and 7AS in the Cranbrook _ Halberd population. In the Sunco _ Tasman cross the highest genetic variance was detected with the QTL on chromosome 2B (31.3%), in the CD87 _ Katepwa cross with the QTL on chromosome 4B (23.8%), and in the Cranbrook _ Halberd 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.
