Abstract

The objective of this work was to select potato clones for industrial processing, cultivated under subtropical and temperate conditions in Southern Brazil. Thirty advanced clones and three cultivars (control) were evaluated in the Spring of 2007 and 2008, and in the Autumn of 2008, in Júlio de Castilhos, RS (subtropical climate condition), and in the Summer of 2008 and 2009, in São Joaquim, SC (temperate climate condition). It was used a randomized complete block design in a factorial arrangement (33 clones in 5 environments), with two or three replicates of ten hill plots. Yield, appearance, chip color, dry matter and reducing sugar contents of tubers were evaluated. There was a significant interaction between clones and environments for all the evaluated traits, except for chip color. The yield and dry matter of tubers were higher in the summer crop. Environmental conditions affected all the evaluated traits. Growing conditions in Southern Brazil allow for the selection of potato clones with enough content of dry matter to meet the potato processing industry requirements.
