| Résumé: | High dry matter content and the color of the final processed product
are among the most important characteristics for the potato processing
industry. The use of isoenzymes for a rapid prediction of these
characteristics in tetraploid potatoes resulting in an increased selection
efficiency by reducing the time required to get good results, was not
completely explored yet. The objective of this study was to determine
the association between the isoenzyme glutamate oxaloacetate
transaminase and the dry matter contents and color of the potato tubers
chips in different genotypes of ten commercial varieties and ten clonal
families of potato (Solanum tuberosum L.) eletrophoretically evaluated.
To determine the association, 2x2 Chi-square contingency tables were
used with correction for continuity. Results of the comparisons indicated
a significant association between the 1.00 band of the evaluated enzyme
and the chips color, which allowed an early estimation by this enzyme of
the effect of frying. Did not have association between the dry matter
and the band 1,00, contradicting other researches with diploid wild
potatoes. |
