At the same time, high yielding varieties were evaluated that were not necessarily early. The bulk selection method was used to advance to the F6 generation. Twenty rive populations from crosses among 10 parents with diverse maturities were evaluated. At F<span class="s1">6</span>, 458 individual .selections were made considering yield per plant, early maturity and visual characteristics.
