Abstract
In a field study simulating commercial practice, the performance of 4x meiotic tetraploids from 4x−2x crosses (Group Tuberosum×(Group Phureja×haploid Group Tuberosum), and their 4x and 2x parents, was studied for total yield, total number of tubers, number of marketable tubers and average tuber weight. Some of the families showed striking heterotic effects for these characters. 38 selected high yielding tetraploids from these families, when evaluated in the next season, gave 80% higher mean yield than the mean of the 4x parents.
