In addition, it is a pillar of food security in many regions and a vital source of income for millions of farmers. However, the production of these grains is sometimes affected by environmental or agronomic management factors, which in turn affect the properties and quality of the grain, which affect the milling quality. The general objective of this research is to determine the milling quality of the promising rice line L-17 in the Guare area, Los Ríos province. It was carried out using a non-parametric design using Kruskal Wallis analysis, including comparisons of means. For this, various parameters were analyzed such as husk weight (g), moisture percentage (%), whole grain weight (g), white mass weight (g), dust weight (g), broken grain weight (g), whole grain weight (g), whiteness percentage (%), amylose and protein percentage (%) and white center which helps us determine the quality of rice grain. Regarding the results in the husk weight variable, it was shown that the L-17 cultivars were inferior to SFL-11, with a result of 249.10 g, and a value of 286.46 g. Regarding the whole weight variable, the result shows that L-17 was inferior, giving a result of 249.10 g and SFL-11 a value of 286.46 g. On the other hand, the variable L-17 powder obtained a higher weight of 96.63 g, unlike SFL-11, it has a weight of 88.25 g. As for the variable whole grain, being superior, L-17 has a weight of 597.32 g while SFL-11 has a weight of 570.09 g. In addition, the variable whiteness L-17 obtained 44.37 % being superior to SFL-11 which obtained 34.91 %. Meanwhile, in amylose L-17 had 31.23 %, unlike SFL-11 which obtained an average of 26.27 %. On the other hand, protein L-17 resulted superior of 9.14%, while SFL-11 obtained an average not so different of 8.33 % observing that there is no significant difference. It is concluded that the cultivars have similar milling characteristics. |
