Popcorn (Zea mays everta) has long been a favourite snack food for consumers and its popularity has increased over time. Quality as well as yield is important in popcorn. The popping volume of popcorn is the most important quality trait. In this study, yield and some quality characteristics of single-cross and three-way cross genotypes and open-pollinated cultivars were compared. In this trial, 21 genotypes were investigated during 1997 and 1998. Seven of them were single crosses, seven were three-way crosses, and seven were open-pollinated cultivars. There were significant differences among genotypes for yield, popping volume, and percentage of unpopped kernels in both years. Cultivar types had similar yields in the first year, when environmental conditions were optimum, whereas hybrid genotypes had lower yield values in the second year because of unfavorable rainfall and temperature. Popping volume was significantly higher in hybrid genotypes than open-pollinated cultivars whereas the percentage of unpopped kernels was c. 50% lower in hybrids. Therefore, well-adapted hybrid cultivars should be grown instead of open-pollinated cultivars under optimum environmental conditions. © 2005 Taylor & Francis Group, LLC.
