RENDIMIENTO DE CUATRO LÍNEAS PROMISORAS DE ARROZ (Oryza sp.), BAJO EL SISTEMA DE SIEMBRA POR TRASPLANTE; UNA PLANTA POR SITIO, EN EL CANTÓN DAULE – PROVINCIA DEL GUAYAS.

Abstract

The present work was carried out with the purpose of evaluating the performance of the four new promising rice lines (PxJ-7, PxJ-17, PxJ-37 and PxJ-38), under the planting system of one plant per site, in the Daule canton, province of Guayas. These varieties were compared with the commercial cultivar SFL-11 as a control. ANDEVA variance statistics, Unrestricted Random Design (DIA), Completely Random Design (DCA), the 95% Tukey test, descriptive statistics, Cluster or conglomerate, Pearson correlation, PROMVAR model were used to determine the relative variability (%) and principal components analysis. The variables measured were: plant height, number of tillers, number of panicles, panicle length, total grains per panicle, length and width of shelled and shelled grains, empty and full grains, percentage of sterility and yield (Kg.ha^-1). Its plant height was lower than the commercial control (SFL-11). Line 17 presented 34 panicles per plant, and an average of 7.3 mm in length in hulled grain. The highest yield was obtained by line 7 with 12611.69 Kg.ha^-1, followed by line 17 which presented 12662.07 Kg.ha^-1. According to the analysis of the 95% Tukey test and the cluster analysis (Euclidean distance) Ward method, the result was that line 17 of the four evaluated was the one with the highest yield with 12,662.07 Kg.ha^-1 , also in the cluster analysis specified that this line is unique.
