Abstract

Proteins of potato clones with a wide range of total protein content and from two different genetic backgrounds were divided into albumin, globulin, prolamin, glutelin and residual fractions. More soluble protein was recovered from older, more mature tubers than was recovered from younger tubers. Differences in amounts of the protein fractions were detected among the clones. However, the amount of each fraction within a clone was highly correlated with total protein. The percentage of the total protein allocated to each fraction remained relatively constant among the clones which are assumed to be producing mature tubers. Soluble protein (albumin plus globulin) correlated highly with total protein in both Andigena and Phureja-Tuberosum' selections.
