Genotype Selection, and Seed Uniformity and Multiplication to Ensure Common Bean (Phaseolus vulgaris L.) var. Liborino

Seed uniformity and stability testing, multiplication, are key steps in the seed supply chain of common bean (Phaseolus vulgaris L.) other crops. Optimizing agronomical practices these phases can ultimately ensure quality availability, germplasm prospective utilization. However, farmers have rarely standardized testing propagation protocols local landraces conserved situ. An example this is Liborino variety (var.), a promising yellow Andean known for its presumably high digestibility adaptation to conditions Cauca river canyon (northwest Andes Colombia), but likely experiencing genetic erosion after decades suboptimal propagation. Therefore, work intended evaluate select locally adapted genotypes var. commercial use, be later multiplied, evaluated by participatory breeding, eventually shared with farmers. Specifically, we 44 accessions six adaption yield field trials at 1100 1400 m a.s.l, AGROSAVIA’s “La Selva” research station 2100 a.s.l. In parallel, carried out multiplication genotype using best guarantee stability. From accessions, nine were well tested conditions. Four exhibited bush type growth habit, while remaining five climbers.
