dc.descriptionRice (Oryza sativa L.), is the staple food in developing countries, with growing global demand due to increasing population and consumption patterns. In Yaguachi, rice cultivation is crucial according to studies and projects. The L-37 rice line is relevant for its high productivity and tolerance to pests and diseases. This research is carried out by field/laboratory with inferential descriptive statistics, the objective was to determine the agronomic and productive behavior of the promising line of rice L-37, which led to the use of a methodology of two treatments, L-37 and SFL-11 in three replications. The following variables were recorded: Plant height (cm), number of tillers, number of panicles, length of panicles (cm), number of total grains per panicle, length (mm) and width (mm) of grains with and without shells; and yield (kg/ha). A non-parametric design of Kruskal Wallis analysis was performed. Regarding the results, the promising L-37 line presented a lower panicle number, obtaining a value of 20.04, compared to the SFL-11 variety (control) that presented 21.46 panicles. The L-37 line presented a lower percentage (17.92%) of span grains, compared to the SFL-11 commercial control variety, which consists of a higher percentage of span grains (21.91%). It is revealed that the promising line L-37 has a planting distance of 26.4 cm between plants, while the commercial variety SFL-11 has a slightly greater distance of 28.23 cm. While there are similarities in the agronomic characteristics of the SFL-11 variety and the promising L-37 line, it is the latter that really shines in terms of yield, producing an impressive range of 6.5 to 7 tons per hectare. This is particularly notable considering that the SFL-11 control variety exhibits similar agronomic behaviors. In their study Reyes et al. (2022) mentions something fundamental about genetics in the continuous improvement of crop quality, of developing new lines that boost agricultural production in Ecuador.es_ES

dc.description.abstractEl arroz (Oryza sativa L.), es el alimento básico en países en desarrollo, con demanda global creciente por aumento de población y patrones de consumo. En Yaguachi, el cultivo de arroz es crucial según estudios y proyectos. La variedad de arroz L-37 es relevante por su alta productividad y tolerancia a plagas y enfermedades. Esta investigación es realizada mediante campo/laboratorio con estadística descriptiva inferencial, el objetivo fue determinar el comportamiento agronómico y productivo de la línea promisoria de arroz L-37, lo que conllevó a utilizar una metodología de dos tratamientos, L-37 y SFL-11 en tres repeticiones. Se registraron las variables de: Altura de planta (cm), número de macollos, número de panículas, longitud de panículas (cm), número de granos totales por panícula, longitud (mm) y ancho (mm) de granos con y sin cáscara; y rendimiento (kg/ha). Se realizo un diseño no paramétrico de análisis de Kruskal Wallis. Con respecto a los resultados, la línea promisoria L-37 presentó un menor número de panícula obteniendo un valor de 20,04, en comparación con la variedad SFL-11 (testigo) que presentó 21,46 panículas. La línea L-37 presentó un menor porcentaje (17,92%) de granos vanos, ante la variedad comercial testigo SFL-11 que consta de mayor porcentaje de granos vanos (21,91%). Se revela que la línea promisoria L-37 cuenta con una distancia de plantación de 26,4 cm entre plantas, mientras que la variedad comercial SFL-11 tiene una distancia ligeramente mayor de 28,23 cm. Si bien existen similitudes en las características agronómicas de la variedad SFL-11 y la línea promisoria L-37, es esta última la que realmente brilla en términos de rendimiento, produciendo un rango impresionante de 6,5 a 7 toneladas por hectárea. Esto es particularmente notable si se considera que la variedad control SFL-11 exhibe comportamientos agronómicos similares. En su estudio Reyes et al. (2022) menciona algo fundamental de la genética en la mejora continua de la calidad de los cultivos, de desarrollar nuevas líneas que impulsen la producción agrícola en Ecuador.es_ES
