Características morfológicas del pasto janeiro (Erioclhoa polystachya), en el cantón Babahoyo - Provincia de Los Ríos

VIII. SUMMARY The Erioclhoa Polystachya denominated in Ecuador grass "Janeiro" is perennial, of creeping behavior, hollow stems and stoloniferous, that produces seeds of low viability. This investigation was carried out with the purpose of identifying and characterizing janeiro grass morphotypes in order to determine the morphological variability of the species. The morphological diversity was explored and analyzed in a sample size of 45 individuals located within the Faculty of Agricultural Sciences of the Babahoyo Technical University located in Babahoyo province of Los Ríos. To evaluate the variability of phenotypic characteristics of the janeiro grass, characterizers used for other studies of the same nature were adapted. As results, the stability of the morphological characters could be evidenced, since all the evaluated descriptors did not surpass 50% of the coefficient of variation that manifests the variability of the descriptors. There was a degree of correlation between leaf area descriptors with leaf length (r = 0,81; p <0,0001) and leaf width (r = 0,63; p <0,0001). Likewise, there was no correlation between dry matter yield and the other descriptors. For the qualitative variables, no type of variability was presented between the evaluated descriptors. Finally, it is recommended to replicate this work in the different livestock areas of the country in order to better characterize this pasture of great importance in the agricultural sector, in addition to using other species to estimate the best agronomic characteristics that could serve to make a selection and improvement of species.
