ORTIZ-TORRES, Enrique et al. Hectoliter weight and seed weight predict popping volume in amaranth. Rev. Mex. Cienc. Agríc [online]. 2023, vol.14, n.6, e3025.  Epub 30-Out-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v14i6.3025.

Studies associated with the popping volume of amaranth (Amaranthus hypochondriacus L.) are practically nonexistent. The objective was to evaluate the relationship between characteristics of plant and raw grain with the popping volume of the popped grain. Between 2014 and 2015 2018-2019, five trials were established in Puebla, Mexico to evaluate the varieties Nutrisol, Revancha, Gabriela, Laura, Diego, Areli and PQ2 and three local populations. Characteristics of plant, raw and popped grain were measured. Positive and statistically significant (p≤ 0.01) correlations were observed between popping volume (PPVL) with hectoliter weight (HLW) (r= 0.56**) and weight of one thousand seeds (WTS) (r= 0.3**). It was also found that WTS and geometric seed diameter positively correlated with popped grain volume with size of 2.38 and 2 mm. Therefore, HLW and WTS could be used to help predict the behavior of popping volume in amaranth genotypes.
