COMPARACIÓN DE LÍNEAS DE SOYA (Glycine max L Merril), BAJO EL SISTEMA DE SIEMBRA CONVENCIONAL

Abstract

This research was carried out on the Sara María farm, in the Santo Domingo de los Amarillos area, Los Ríos province, Ecuador, with the purpose of comparatively studying introduced soybean lines under the conditions of the area and with conventional management. The materials used were lines from Brazil, Bolivia, Colombia and the United States (S-06, S-128, S-959, S-891, S-981, S-1001, S-1013, S-81, 10002,10032, S-917, 10013) and local control varieties provided by the National Institute for Agricultural Research (INIAP 307, INIAP 309, INIAP 310), (INIAP). A completely randomized block design with 15 treatments and 3 repetitions was used and variables related to earliness, agro-botanical characters, yield components and phytosanitary behavior were studied. It turned out that the lines S-1013, S-81 and S-917 obtained yields between 3511 and 3562 kg/ha, while the controls such as INIAP 307 and 309 a surpassed the lines with averages of 3599 and 3655 kg/ha respectively. Three of the lines studied are similar to the controls both for their agronomic characteristics and yield. It is recommended to continue the study of the most outstanding materials in other areas of the country
