Resumen
El presente ensayo se realizó en la Estación Experimental “Pichilingue” del
cantón Quevedo, Provincia de Los Ríos. El lugar presentó una temperatura
media de 26,5°C, precipitación anual de 1970 mm, humedad relativa de
83,2% y altitud de 120 msnm. El suelo presentó topografía plana y textura
franco-limosa.
El propósito de la investigación fue evaluar líneas en comparación con
testigos locales. Se empleó el diseño bloques completos al azar con 3
repeticiones y 19 tratamientos compuestos por las 16 líneas y las tres
variedades que se utilizaron como testigos: INIAP-307, INIAP-308 y IJ-112-
397.
En cada una de las variables evaluadas se realizo el análisis de varianza y la
prueba de Tukey al 5% de probabilidad con el objeto de establecer
diferencias entre las medias de los tratamientos.
Las líneas que presentaron el mayor rendimiento fueron la 10427 con 4727
kg·ha-1 conjuntamente con las líneas 10728 y 10485 por lo que se concluyó
que estas fueron los genotipos que presentaron mejor adaptación a la zona y
por consiguiente tuvieron una mayor productividad, además que las líneas
10002 y 10794 presentaron menor producción posiblemente debido a
problemas de adaptación a la zona ya que su rendimiento fue bajo
comparado con el de los demás genotipos. La mayoría de las líneas tuvieron
This test was performed in the "Pichilingue" Experimental Station Quevedo canton, Los Rios Province. The place provided a temperature average of 26.5 ° C, annual rainfall of 1970 mm, relative humidity 83.2% and altitude of 120 meters. The presented flat topography and soil texture silt loam. The purpose of the research was to evaluate lines compared to Local witnesses. The randomized complete block design was used with 3 repetitions and 19 treatments consist of 16 lines and three varieties used as controls: INIAP-307, INIAP-308 and IJ-112- 397. In each of the evaluated variables was performed analysis of variance and Tukey test at 5% probability for the purpose of establishing differences between treatment means. The lines that showed the best performance in 4727 were 10427 kg ha-1 in conjunction with the 10728 and 10485 lines so it was concluded these were the genotypes showed better adaptation to the area and therefore had a higher productivity, and that the lines 10002 and 10794 had lower production possibly due to problems of adaptation to the area since its yield was low compared with the other genotypes. Most lines had
