Sterility was studied in 262 varieties of potatoes in the Centinela Experiment Station, Puerto Octay. Abundance and premature abscission of the flowers and fruit, condition of pollen and results of hand pollination were observed for two years.
Tests were made using 193 varieties as females and 70 as males to determine suitability in future crosses.
