Summary: Se presenta un resumen de las caracteristicas de los primeros ensayos de viveros internacionales y los resultados de los primeros experimentos. El ensayo IBYAN (1976) estuvo formado por 20 var. del CIAT + 5 var. locales. Se distribuyeron 90 experimentos entre 30 paises. El procedimiento experimental fue uniforme y se instruyo a los colaboradores para que utilizaran en lo posible practicas culturales comunes. En cada localidad se efectuo un analisis de varianza para cada una de las variables. La var. P758 presento el mayor rendimiento, un prom. de 3700 y 3200 kg/ha en Chile y Japon, resp. En general, los rendimientos obtenidos en las localidades de las zonas templadas fueron mas altos que los de las zonas tropicales. Las var. de semilla negra produjeron los mayores rendimientos. En las zonas templadas se registro floracion tardia. Los periodos mas cortos desde la siembra hasta la maduracion fisiologica se registraron en las zonas tropicales de alta temp (34 grados centigrados max, 24 grados centigrados min). (CIAT)Summary: 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)
