dc.description | Rice is the most relevant fundamental production grain on a global scale, thanks to the total extent of its cultivation throughout the world and the large number of people who rely on its harvest, offering work to numerous families. The objective of this study was to determine the milling quality of the promising L-17 rice line grown in the Pimocha area, Los Ríos province. Two rice cultivars were used with three repetitions: L-17 and SFL-11. The determination of milling quality is carried out in the FACIAG-UTB Grain Quality Laboratory. The variables evaluated were: weight (g) of husk, weight (g) of brown rice, weight (g) of white mass, weight (g) of powder, weight (g) of broken grains, weight (g) of whole grains, whiteness, white center (%), percentage of amylose and protein. For statistical analysis, the non-parametric Kruskal Wallis analysis design was used, including comparison of means. Regarding the results, it is calculated that in the whole grains variable, the promising line L-17 presented the highest value with 606.45 g (60.64 %). The amylose content in the commercial variety SFL-11 was 31.57%, while the promising line L-17 obtained a value of 30.20%, almost similar results in the two cultivars. The percentage of whiteness in the commercial variety SFL-11 was 42.87%, while the promising line L-17 obtained a value of 40.90%. Regarding proteins, it was determined that the promising line L-17 obtained a value of 7.97%, while the commercial variety SFL has an average of 7.80%, observing that there is no difference in protein between the two cultivars. It is possible to conclude that the milling quality of these two studied cultivars is very similar. | es_ES |

dc.description.abstract | El arroz es el grano fundamental de producción más relevante a escala global, gracias a la extensión total de su cultivo en todo el mundo y la gran cantidad de personas que se apoyan en su cosecha, ofreciendo trabajo a númerosas familias. El presente estudio tuvo como objetivo determinar la calidad molinera de la línea promisoria de arroz L-17 cultivadas en la zona de Pimocha, provincia de Los Ríos. Se utilizaron dos cultivares de arroz con tres repeticiones como son: L-17 y SFL-11. La determinación de la calidad molinera se realizó en el laboratorio de Calidad de granos de la FACIAG-UTB. Las variables evaluadas fueron: peso (g) de cascarilla, peso (g) de arroz integral, peso (g) de masa blanca, peso (g) de polvillo, peso (g) de granos quebrados, peso (g) de granos enteros, blancura, centro blanco (%), porcentaje de amilosa y proteína. Para el análisis estadístico se utilizó el diseño no paramétrico de análisis de Kruskal Wallis incluyendo la comparación de medias. En cuanto a los resultados se determinó que en la variable granos enteros la línea promisoria L-17 presento el mayor valor con 606.45 g (60.64 %). El contenido de amilosa en la variedad comercial SFL-11 fue de 31.57 %, mientras que la línea promisoria L-17 obtuvo un valor de 30.20 %, resultados casi similares en los dos cultivares. El porcentaje de blancura en la variedad comercial SFL-11 fue de 42.87 %, mientras que la línea promisoria L-17 obtuvo un valor de 40.90 %. En cuanto a las proteínas, se determinó que la línea promisoria L-17 obtuvo un valor de 7.97 %, mientras que la variedad comercial SFL tiene un promedio de 7.80 %, observando que no hay diferencia de proteína entre los dos cultivares. Se logra concluir que la calidad molinera de estos dos cultivares estudiados es muy parecida. | es_ES |
