Determinación de contenido de amilosa y características molineras en cultivares de arroz (Oryza sativa L.), en la zona de Babahoyo, provincia de Los Ríos

The present research was conducted in the Grain Quality Laboratory of the Technical University of Babahoyo, Ecuador. The amylose content and milling characteristics of seven rice cultivars were determined, which are IMPACTO, SFL-11, VALOR, ELITE, FERÓN, ARENILLAS and LÍNEA SN that came from the Babahoyo area, Los Ríos province. The studied variables were shell (%), integral grain (%), dust (%), classified rice (%) or whole grains, broken rice grains(%), white belly (%), amylose content (%) and protein content (%). For the statistical analysis of the variables, the analysis of variance ANDEVA, Completely Random Design (DCA), Tukey's test at 95%, descriptive statistics, Euclidean Cluster, Pearson correlation, PROMVAR model for the determination of relative variability (%) and principal components analysis were used. Regarding the results, in this study it was determined that there are cultivars of particularly good milling characteristics in the area in question, highlighting that certain cultivars do result with the advantages mentioned. The cultivar that presented the highest percentage of classified grain yield was the SFL-11 cultivar. The cultivars that presented the lowest percentage of shell were: SFL-11 and Impacto. The named cultivars Impacto and SFL-11 showed the highest levels of whole grain. The Elite cultivar was the one that presented the lowest value in the variables broken grain rice and dust. The highest percentage of amylose content were Arenillas, Elite and Impacto.
