Variabilidad agronómica y productiva de líneas F2 de arroz (Oryza sativa L.), provenientes de cruzas con un progenitor masculino portador del gen CLEARFIELD

This experimental test was carried out at the “San Pablo” Experimental Farm of the Faculty of Agricultural Sciences, Technical University of Babahoyo, located at KM 7.5 of the Babahoyo - Montalvo road. The main objective of the study was to evaluate the “Agronomic and productive variability of rice F2 lines (Oryza sativa L.), from crosses with a male parent carrying the CLEARFIELD gene”. The variables that were evaluated are: Vigor, Flowering, Vegetative cycle, Plant height (cm), Panicles per plant, Panicle length (cm), Grains per panicle, Vain grains per panicle Sterility%, weight of 1000 grains (g), Yield (grain / plant), Yield (g / plant), Shape of grain, Length and Width of grain (mm). According to the results obtained, it was possible to verify that all the studied treatments presented a high agronomic variability, since in all the variations high significant differences are registered. In relation to the data obtained, regarding the yield variable (g / plant), it was found that the progenies FI-107 / BR-101, FE-103 / BR-101, G-111 / BR- 101, FL-109 / BR-101 and parental BR-101 were significantly superior to the rest of the evaluated treatments, presenting means of 39.15; 39.33; 39.68; 42.13 and 46.00 g / plant. Twelve individuals with the best productive characteristics were selected, as a result of the combination of the best individuals, where four characteristics were considered, such as: number of panicles per plant, panicle length (cm), yield (g / plant) and length of shelled grain (mm).
