SUMMARY The present research work was carried out at the Experimental Farm, "El Palmar", belonging to the Technical University of Babahoyo, located at the Project CEDEGE, province of Los Ríos, at Km 12 of the Babahoyo - Montalvo road. The present work consisted in “The identification of superior segregants in heterozygous populations of japonica rice (Oryza sativa L. ssp. japonica). The objectives of this research were: To determine the populations of superior genetics in japonica rice F2 segregants by individual plant selection and to identify the best japonica rice using F2 segregators with outstanding agronomic characteristics. During the development of the work, all the agricultural work and practices required for rice cultivation were carried out, such as: soil analysis, soil preparation, planting, irrigation, fertilization, weed control and harvesting. The agronomic variables evaluated were: Vigor, Vegetative cycle (days), Panicle number per plant, Leaf length (cm), Banner leaf width, Plant height (cm), Panicle length, Panicle, Sterility (%), Yield (g / plant), Weight of 1000 grains (g), Grain length (mm), Grain width (mm) and Grain shape. The different variables studied were analyzed using non-parametric statistics using the Kruskal-Wallis comparison method. Frequency distribution tables and figures such as: dispersograms, were also used to identify plants of selected segregants and parents. In this study it is recommended to continue the studies in the following generations, in this case with F3, since in the results of F2, it was observed that there are populations of high yield and excellent agronomic characteristics that will serve to have a new variety in the future, with the selection that is made in the individuals studied. |
