Metodologia y analisis de resultados de los primeros ensayos de Viveros Internacionales de Rendimiento y Adaptacion del Frijol, IBYAN
A summary of the characteristics of the Ist international trials and the results of the lst expts are given. The 1976 IBYAN trial consisted of 20 CIAT var. + 5 local var. Ninety expts were distributed among 30 countries. Exptl procedures were uniform and the collaborators were instructed to use common cultural practices whenever possible. An analysis of variance was conducted for each of the variables at each locality. The var. presenting the highest yields was P758, with an av of 3700 and 3200 kg/ha in Chile and Japan, resp. In general, the yields obtained in temperate zones were higher than those of tropical zones. Black-seeded var. produced the highest yields. In temperate zones, late flowering was observed. The shortest periods from planting time to physiological maturity were registered in tropical areas with high temp (34 degrees Celsius max. 24 degrees Celsius min). (CIAT)
