In Brazil, common bean (Phaseolus vulgaris) seed lots are classified using sieves into lots of small, medium and large seed size, which are then separately sold in standard 40-kg bags. However, the effect of seed size on common bean performances remains inconclusive, and therefore the objective of this research was to study the effects of common bean seed size on seed physiological potential. Three common bean varieties, BRS Estilo, BRS Horizonte and BRS Madrepérola, were each sorted by size using oblong sieves, resulting in small, medium and large seed lots per variety. Seed lots were classified according to thousand seed mass, and their physiological potential assessed using several tests. Thousand seed mass indicated wide differences among seed lots, but within each variety, no differences in seed physiological potential were observed based on seed size. Only one variety, BRS Horizonte, showed significant differences in germination among seed lots of different sizes, but all size classes had high germination of 92% or more. Germination first counts showed little variation among seed lots, and results of the other vigor tests based on seedling growth agreed with first count results. Although vigor tests based on seedling growth indicated a possible size effect on early field development of plants from large seeds, seed size of common bean does not appear to affect seed physiological potential. |
