%X thirty two bean accesses (phaseolus vulgaris l.) were evaluated for the influence of eight characters of agronomic importance the production of grains for unit of area, in lages/sc. the experiment, in randomized blocks with four repetitions, was conducted during the period off-season in the agricultural year of 1996/97. this work aimed estimating the degree of association between grain yield and its secondary components. the first group of variables (primary) was constituted by the number of grains per pod, number of pods per plant, weight of a thousand grains and the population of plants (pop). the second group (secondary), was constituted by the number of days between emergence and flowering (fl), number of days between emergence and harvesting point (mc), plant stature (ep) and the height of first pod insertion (pil). for the analysis of the trail coefficient, the direct and indirect effects of primary characters nlp and pmg were characterized and evaluated, revealing the large direct effects associated with the high correlation. the nlp was highly influenced by plants of shorter cycle and higher stature. the trail coefficients allow to point out that the largest direct effects on the yield of grains nlp are mainly associated to pmg, ngl and cycle of the plant.
