Regional variability in Phaseolus vulgaris L. (II.) Seed character frequencies in Transylvania

Abstract

Attempt was made to evaluate gene frequencies using seed characters registred in Phaseolus vulgaris, cultivated in traditional multicropping (Zea + Phaseolus + Cucurbita) in a sample territory in Transylvania (Romania). The highest frequencies were found in the case of characters determined mostly by I, T, D, and at gene group (according to Prakken 1972); mottled seed coat and violet colour was relatively rare. The short and spherical forms are more frequent, as the long and compressed, with the notable exception of white compressed types. Our knowledge in Phaseolus genetics allowed only a first approach in a very restricted number of characters.
