The aim of this study was to evaluate genetic variability and identify heterotic groups in synthetic populations of popcorn, using diallel crosses. Thus, nine synthetic populations were crossed using complete diallel scheme. The GY and PE traits of 36 hybrids and reciprocals were evaluated in a randomized complete block design with 72 treatments and two replicates in two years. The effects of non-additive genes were the most important in the genetic control of these traits, indicating a favorable situation to produce hybrids. The reciprocal effect is mainly due to non-maternal effects for GY and PE. The highest GY values were obtained for the 02 x 08, 04 x 09, 05 x 09, and 01 x 09 crosses and the highest PE were obtained for the 07 x 01 and 03 x 04 crosses. The exploitation of synthetic populations from S3 lines can be an alternative to increase the genetic variability for grain yield and popping expansion in popcorn breeding programs. 2019 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303060470013 https://www.redalyc.org/journal/3030/303060470013/ https://www.redalyc.org/journal/3030/303060470013/html/ https://www.redalyc.org/journal/3030/303060470013/303060470013.epub https://www.redalyc.org/journal/3030/303060470013/movil 10.4025/actasciagron.v41i1.39497 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
