Potential use of ‘landrace’ bean cultivars in organic farming system

Abstract

The genetic resources maintenance and viability of common bean crop production are based sustainable farming practices and landrace adapted to local conditions. The objective of this work was characterize the common bean landrace in organic cultivation in the Midwest of Santa Catarina, Brazil South. The experiment was carried out in Campos Novos - SC, at 2011/12 growing season. Where evaluated 22 landraces and 4 commercial cultivars under organic cultivation system. The traits evaluated were: plant height, first pod, stem diameter, number of nodes on the main stem, number of pods per plant, pod length, number of seeds per pod, number of loci per pod, number of loci aborted and weight of 100 seeds. The genotypes showed genetic diversity for all characters except number of nodes per plant. The BAF’s 102, 13, 23, 42, 47 and 75 were favorable for organic cultivation with good traits for plant architecture and yield components, pointing to increase seed yield in the organic crop system.
