Drought Effects to the Dry Bean Local Population Productivity

Abstract

The study presents the main characteristics of 10 local bean population (Phaseolus vulgaris L. convar. nanus). Considering the total opposite weather conditions in 2011 and 2012, growing bean allowed their evaluation in drought conditions. High temperatures and relative low air humidity determined a 76.61% yield diminuation at V7 in 2012 comparative to 2011. The 13.52% yield diminuation from an year to another registered at V1 corroborated with a 0.25 drought susceptibility index (DSI), recommands using this provenience in drought breeding works for this species.
