Because of the complexity that yield components have, and the advantages that early varieties have for farmers considering actual yield components, genotype evaluation was initiated in 1985 to Identify early maturity types. 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 F6, 458 individual .selections were made considering yield per plant, early maturity and visual characteristics. At F7 aprogeny test was made to evaluate F6 effectiveness Grain yields were reduced which is in part explained by the management given to the individual F6 selections compared to F7. Regarding early maturity, various were found with acceptable grain yields which are not common amongst early maturity varieties in the southeastern region of Guatemala (above 1-5 Mg/ha).
