Seeds of the bean cultivar (Phaseolus vulgaris L.) Carioca 80 were irradiated with gamma-rays to induce mutants with higher basal height (sum of hypocotyl and epycotyl). A mutant with 1.7 time greater basal height was obtained in the M2 generation from 24 krad treatment. Genetic studies showed that the mutation was a monogenic recessive allele. This is the first report of an induced mutant with this characteristic.
