Cuir clib leis | Achoimre: | The research was conducted at the Experimental Station South Coast "Dr. Enrique Ampuero pareja " of INIAP, located at km 26 of road Duran-Tambo, parroquia, Virgen de Fatima, Canton Yaguachi, Province Guayas, located 17 m, 02 º 15 'south latitude and 79 º 54' west longitude. The objectives were to: Select segregating F1 superior agronomic characteristics in order to continue breeding. Evaluate 91 F1 populations from single crosses Were evaluated 91 F1 populations of rice, caused national rice program of the EELS INIAP, populations were evaluated in the open. For the effect of different variables were analyzed by measures of central tendency (mean, mode) and dispersion (variance, standard deviation and range). We also frequency distribution tables, charts, such as frequency histograms and frequency polygons. The agronomic variables evaluated were: Vigor, Flowering (days), Vegetative cycle (days), No. tillers per plant, No. panicles per plant, length flag leaf (cm), Width flag leaf (cm) Blade length 2 (cm) blade width 2 (cm), plant height (cm), panicle length (cm), grains / panicle, sterility (%), 1000 grain weight (gr), yield per plant (gr), grain length (mm) , grain width (mm), White Center. |
