Abstract
A 2-year study of 10 crosses involving 20 different tetraploid parents from the USDA potato breeding program showed significant differences in tuber content of total nitrogen (TN, crude protein) and total solids among offspring means and among parents. Offspring TN ranged from 0.20–0.50% in 1968 and from 0.20–040% in 1969 (fresh-weight basis). Heritabilities in the narrow sense ranged from 24–34% (1 and 5 replicates, respectively) for TN and from 24–38% for solids. TN selection was indicated to be potentially as effective as solids selection. The expected gain from selecting 10 of 100 clones in a 5-replicate, 1-year test was calculated as 6.4% of the parental mean for TN and 3.4% for solids.
