the relationship between available methionine concentration and quantitative phaseolin variation was studied in the progenies of crosses involving several genotypes with different levels of phaseolin and/or available methionine, among which were a P. coccineus subsp. coccineus line ("Mexican Red Runner") without detectable phaseolin and a Mexican wild bean accession (PI325690-3) with reduced phaseolin levels. In all the progenies studied, with the exception of those in population 6, higher phaseolin levels led to increased available methionine concentrations, indicating that phaseolin is a major source of available methionine in common bean seeds. In population 6 ("Sanilac"x 15R148), no association was observed between phaseolin and available methionine concentrations, possobly because of the influence of other factors such as additional methionine-rich proteins or seedcoat tannins. Qualitative phaseolin variation among wild and cultived common beans was analyzed using one-dimensional sodium-dodecyl-sulphate polycrylamine gel electrophoresis (SDS/PAGE) and two-dimensional isoeletric focusing SDS/page. Wild beans exhibited a wid variety of phaseolin patterns; "B", "CH", "M", "S", and "T". Landrace cultivars showed the "C", "S", and "T" types described previously, as well as three new patterns: "A", "B", and "H". Cultivars with "B" and "S" phaseolin types generally had smaller seeds than "A", "C", "H", and "T" phaseolin cultivars.
