Phenotypic differences in adaptation to combined stress of inadequate P supply and drought (BASE 80 trial)
A field trial was conducted during the dry season (May to July 2016) at Darien, Valle del Cauca-Colombia, The BASE (Bean Abiotic Stress Evaluation). The BASE trial included 80 bean genotypes: 58 belong to Mesoamerican gene ...
Identification of genes and genetic mechanisms contributing to heat tolerance. Sources of heat tolerance
Two temperature controlled greenhouses were used to conduct a trial at CIAT. A set of 192 genotypes including 101 accessions of P. vulgaris, 81 accessions of P. acutifolius and 10 accessions of P. parvifolius, were evaluated ...
Breeding lines with improved performance under P and water limitation. Parental crosses for low P in acid soil identified
Objective and intended output:
Root attributes contribute to acquisition of immobile nutrients such as P. Genotypic variation in root crown in response to P availability in soil has been observed before. The main objective ...

Phenotypic evaluation of the effect of high temperatures (2°C and 4°C above ambient temperature) on elite common bean lines
A heat tolerant trial of Andean beans was planted in Alvarado (Tolima) (July to November 2016). A total of 157 individual selections were planted. A total of 8 F1.3 and 31 F1.4 were selected under conditions of heat stress. ...

Identifying genes and QTL associated with heat tolerance. Genomic regions for heat tolerance identified in interspecific progeny
Initial results with GBS suggested that introgression had occurred across a wide part of the genome when a large number of lines were considered (Figure 1). GBS also suggested that heat tolerant line INB 841 had very ...
Trade-Offs in Multi-Purpose Land Use under Land Degradation
Land provides a host of ecosystem services, of which the provisioning services are often
considered paramount. As the demand for agricultural products multiplies, other ecosystem services
are being degraded or lost entirely. ...
Breeding lines with improved performance under P and water limitation. Improved lines for combined stress of drought and low P identified
Simple, 3-way and double (4 parent) crosses are created among stress tolerant parents, and including parents for high grain iron. F2 populations are screened under drought stress and promising families are harvested in ...
15N evaluated in elite breeding lines
A total of 100 bean genotypes including 67 ENF lines, 13 CGA lines, MAC lines, MBC lines and 5 checks were evaluated for SNF ability and seed yield. Field trials were conducted at two locations (Darien and Popayan) in ...
