Root hair length evaluated
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 ...
Demand is quantified for common bean
This objective was completed ahead of schedule, but a summary is presented here. Data on production of pulses and human population suggest that per capita consumption must be declining. This raises critical questions among ...
Climbing beans with acceptable color, resistances and fixing more than 50 kg/ha N tested in African production environments
Improved lines are both developed locally and received from CIAT headquarters in Colombia. Initial testing of lines has often been carried out with the national program of Rwanda, and in CIAT’s facilities within the campus ...
Developing new bean products in Kenya, Uganda and Rwanda through private sector collaborations
One of the initiatives targeted “dry” precooked beans and the other “wet” precooked beans. The “dry” precooked bean is dehydrated after processing but retains the main character of the dry beans (colour, storage under ...
Compilation of seed distribution
Improved access to quality seed of improved varieties of their choices by women farmers through various mechanisms including deliberate efforts to engage women farmers in the participatory varieties selection; empowerment ...
Common bean lines identified as resistant to soil pathogens to serve as sources for Andean beans
Greenhouse infrastructure was adapted to control and monitor constantly soil moisture through the installation of an automatic watering system that included pipes, sensors, and data loggers (Figure 1). We are reporting the ...
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. ...
