QTL for body weight and condition factor in Atlantic salmon (Salmo salar): Comparative analysis with rainbow trout (Oncorhynchus mykiss) and Arctic charr (Salvelinus alpinus)

Article Abstract:

Quantitative trait loci (QTL) affecting body weight (BW) and condition factors in North American Atlantic salmon (Salmo salar) are examined with the help of genotypes at 91 microsatellite loci in three full-sib families. AS-8 showed a significant QTL accounting for 20.1 percent of the variation in BW and AS-14 showed significant QTL for condition factor accounting for 24.9% of the trait variation.

Sex-linked quantitative trait loci for thermotolerance and length in the rainbow trout

Article Abstract:

The correlation between growth traits and upper thermal tolerance (UTT) in rainbow trout is explained by quantitative trait loci (QTL) localized to the same linkage groups. The findings indicate minor evidence that correlation between UTT and FL is partially determined by one or more sex-chromosomal QTL.
