SNF on Climbing bean under drought


henotypic analysis of SNF lines of climbing bean for their tolerance to abiotic stress conditions of drought stress. Research Staff Responsible: Norma Constanza Barbosa Torres (CIAT)

Planting date: July 13th 2017 Evaluation date 40dds (Flowering)
90 dds -120 (harvest)

 Objective: Identify SNF response of common bean genotypes under drought, additionally identify genotypes efficient in DRI utilization when dependent on N2 fixation as a source of Nitrogen  Hypothesis: Some genotypes will show Nitrogen Fixation efficient and more adaptation to drought as abiotic stress
