“…These are the fraction of individuals that exceed parental phenotypic values in either a negative or positive direction (Rieseberg et al, 1999). The results observed in this study shows that is possible to observe transgressive genotypes for PE, a well‐known additive trait (Yongbin et al, 2012). Some explanations have been reported for transgressive phenotypes in segregating hybrid populations for various additive traits (Buerkle et al, 2000; Lowe and Abott, 2004), but the main consensus is a complementary action of additive alleles that are dispersed between the parental lines, assuming that parental lines are fixed for sets of alleles that have opposing effects within lines.…”

Popcorn is a popular snack food with higher economic value compared to field corn varieties of maize (Zea mays L.), but displays less favorable agronomic performance and greater susceptibility to diseases. The objective of the present work was to study the mode of inheritance of popping expansion (PE) from three different crosses of popcorn × flint corn with a classical model and a mixed model using inbred lines derived from tropical germplasm. The study will investigate if PE is encoded by one or two major genes, a few genes with large effect, or multiple genes of small effect. Four generations (P1 and P2, F1, F2, BC1‐Popcorn and BC1‐Flint) from each cross were evaluated in field experiments in the main growing season of 2013/2014, in two environments. A randomized complete block design was used, with a nested split‐plot arrangement of treatments with four replicates. Means of the four generations were determined for PE. A weighted least squares analysis of variance based on the generation means method was used to perform joint scaling tests on the data from each generation. Maximum likelihood estimators were used to test the effect of major genes and/or the presence of polygenic loci affecting the trait. Although inheritance studies with plot means can be used to estimate genetic effects, the effect numbers can be overestimated. In the current study, PE in popcorn vs. flint crosses was controlled by a major additive gene in conjunction with polygenic modifiers acting in both additive and dominant fashions. Core Ideas Popping expansion is a trait that exhibits quantitative inheritance. Knowledge about the genetic control will aid in breeding programs. We used contrasting crosses and a maximum likelihood approach for inheritance study. Popping expansion is controlled by additive gene with different modifiers.

“…An important detail that possibly hampers to choose the most suitable tester is the fact that the two main traits of the crop, popping expansion and grain yield, which should be evaluated together, have different mechanisms of inheritance (Pereira and Amaral Júnior 2001). Popping expansion is controlled by a small number of genes and there is predominance of additive gene action (Yongbin et al 2012;Rodovalho et al 2014). On the other hand, grain yield is genetically controlled by a large number of genes with predominance of non-additive gene effects.…”

Popped grain sorghum [Sorghum bicolor (L.) Moench] has developed a niche among specialty snack‐food consumers. In contrast with popcorn (Zea mays L.), sorghum has not benefitted from persistent selective breeding for popping efficiency and kernel expansion ratio. Although recent studies have already demonstrated that popping characteristics are heritable in sorghum, the discovery of quantitative trait loci (QTL) for these traits could help expedite and streamline the breeding process. To that end, the objective of this study was to identify regions of the sorghum genome associated with kernel popping traits. Using digital genotyping technology in conjunction with linkage mapping methodology, QTL were identified for kernel popping efficiency and kernel expansion ratio. Additionally, sets of QTL were identified for desirable traits including kernel weight, kernel diameter, kernel hardness, and kernel color. These results provide an initial assessment of regions of the sorghum genome that harbor trait loci controlling the popping quality of sorghum kernels and provide a basis for further detailed genetic studies of this relatively new use for food‐grade sorghum grain.
