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 c...

Metodologia y analisis de resultados de los primeros ensayos de Viveros Internacionales de Rendimiento y Adaptacion del Frijol, IBYAN
The genetic changes occuring in av. productivity, adaptation, and response to environments with different levels of yield for black-colored grain material selected by CIAT during 1976-79 are examined. Data from 124 expt. of the International Bean Yield and Adaptation Nursery (IBYAN) of black bean...

A yield trial with 25 black bean varieties was carried out on the CIAT experimental farm (Palmira, Colombia) to ascertain the efficiency and accuracy of a 5 x 5 lattice design with different no. of replications (2-6) and plot sizes (1, 2, 4 and 6 rows/plot with 1.5, 3.0, 6.0 and 9.0 m(2) areas, r...

Eficiencia y precision del diseno en latices bajo distinto numero de repeticiones y tamano de parcela en ensayos de rendimiento de frijol (Phaseolus vulgaris L.)
Using the data generated by VEF (vivero equipo de frijol) and EP (ensayo preliminar de rendimiento) nurseries during 1979-86, the progress of the CIAT Bean Program during this 8-yr period of plant breeding effort is described in terms of the production of disease resistant lines and the attainmen...

The simultaneous effect that lateral and end border rows may have on yield was studied in experimental plots at CIAT (Palmira, Colombia), using 25 black bean varieties in a 5 x 5 balanced lattice design with 6 replications. Plots measured 12 m(2) (6 rows, 4 m long). Unharvested end rows measured ...
