O-OLAN, Micaela de la et al. Standardization of the busted method for the experimental evaluation of popcorn. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.7, pp.1471-1482.  Epub 30-Set-2020. ISSN 2007-0934.

Mexico is the center of origin of the corn and, therefore, has the vital importance of conserving the germplasm and maintaining the genetic diversity of this crop in the presence of pests and diseases, or of other types of natural phenomena that end with the dominant varieties that they are usually planted in other countries. In Mexico, a great diversity of varieties of this cereal is sown. The popcorn maize is listed as the oldest and is currently in danger of extinction. Popcorn has high fiber, vitamins, minerals, proteins and antioxidants, also help lower cholesterol and control diabetes. Therefore, it is very important to establish a standard busted protocol of popcorn, which allows the evaluation of the genotypes in a consistent manner in the different breeding programs. In this work, the influence of genotype, sample size, time of exposure to microwaves, and moisture of the grain on the busted characteristics of two popcorn maize genotypes, one commercial yellow and one experimental hybrid was evaluated. Significant differences were found in the variables evaluated. The commercial genotype obtained the highest volume of expansion (27.11 cm3), using 2:45 min in the microwave, and with a humidity of 12%; while in the hybrid genotype it is recommended to use 2:30 min and a humidity of 13%, to obtain the greatest volume of expansion (9.48 cm3).
