dc.description | The following study was carried out in the Daule canton, province of Guayas, with the objective of categorizing the method of planting three-four plants per site, commonly known as "mateado", four promising lines of rice PxJ-07, PxJ-17, PxJ-37 and PxJ-38 were used, which have been genetically obtained from the species Oryza sativa L. ssp. japonica and Oryza rufipogon G. or also called Puyón; in addition, an SFL-11 commercial control was used. Samples were taken in batches of 1 m2 in 3 repetitions for each line/cultivar. The data were analyzed by applying the Random Restricted Design (D.I.A) in the agronomic variables: number of tillers (NMP), plant height (cm) (AP), panicles per plant (NPP), panicle length (cm) (LP), grains per panicle (NGP), grain length (mm) (LGC) and grain width (mm)(AGC) with shell and grain length (mm)(LGD), grain width (mm)(AGD) without shell. To analyze the yield variable (Kg.ha-1), the Completely Random Design (DCA) was performed, as well as the Tukey test at 5%, Cluster analysis, Pearson correlation, relative variability (%) and principal components analysis. Regarding the results, Tukey's test and the analysis of relative variability (%), identified promising lines 7 and 38 with the highest yields (Kg.ha-1) and low variability (%). The descriptive statistics detected that the variables with differentiation criterion "greater is better" were NPP, LGD and Kg.ha-1, where the best results were presented in line 38 with 37 panicles, line 7.3 mm in husked grain length and line 7 with a yield of 13,411.58 Kg.ha-1. The Cluster analysis determined grouped the promising lines and the commercial control into two classes, presenting similarity for Class I the commercial control SFL-11 and the promissory line 37; for Class II promising lines 7, 17 and 38. Through Pearson's correlation analysis, it was identified that the yield variable (Kg.ha-1) was highly correlated NMP, NPP, LP and AGD. | es_ES |

dc.description.abstract | El siguiente estudio se realizó en el cantón Daule, provincia del Guayas, con el objetivo de categorizar el método de siembra tres-cuatro plantas por sitio, comúnmente conocido como “mateado”, se utilizaron cuatro líneas promisorias de arroz PxJ-07, PxJ- 17, PxJ-37 y PxJ-38, mismas que han sido genéticamente obtenidas a partir de las especies Oryza sativa L. ssp. japonica y Oryza rofipogon G. o también denominada Puyón; además, se utilizó un testigo comercial SFL-11. Se tomaron muestras en lotes de 1 m2 en 3 repeticiones por cada línea/cultivar. Los datos fueron analizados aplicando el Diseño Irrestricto al Azar (D.I.A) en las variables agronómicas: número de macollos (NMP), altura de planta (cm)(AP), panículas por planta (NPP), longitud de panícula (cm)(LP), granos por panícula (NGP), longitud de grano (mm)(LGC) y ancho de grano (mm)(AGC) con cáscara y longitud de grano (mm)(LGD), ancho de grano (mm)(AGD) sin cáscara. Para analizar la variable rendimiento (Kg.ha-1), se realizó el Diseño Completamente al Azar (D.C.A), asimismo se usó el test de Tukey al 5%, análisis de Clúster, correlación de Pearson, variabilidad relativa (%) y análisis de componentes principales. En cuanto a los resultados, el test de Tukey y el análisis de variabilidad relativa (%), identificaron a las líneas promisorias 7 y 38 con los más altos rendimientos (Kg.ha-1) y baja variabilidad (%); la estadística descriptiva detectó que, las variables con criterio de diferenciación “mayor es mejor” fueron NPP, LGD y Kg.ha-1, en donde los mejores resultados se presentaron en la línea 38 con 37 panículas, la línea 7,3 mm en longitud de granos descascarados y la línea 7 con un rendimiento de 13.411,58 Kg.ha-1. El análisis de Clúster determinó agrupó a las líneas promisorias y al testigo comercial en dos clases, presentando similitud para la Clase I el testigo comercial SFL-11 y la línea promisoria 37; para la clase II las líneas promisorias 7, 17 y 38. Mediante el análisis de correlación de Pearson se identificó que la variable rendimiento (Kg.ha-1) estuvo altamente correlacionada NMP, NPP, LP y AGD. | es_ES |
