| Summary, etc |
En la segunda estacion de crecimiento de 1984, se utilizo un no. reducido de materiales para evaluar la estrategia de seleccion actual y estudiar los mecanismos de tolerancia a la sequia. Los nuevos materiales evaluados incluyeron 14 lineas del progama nacional del Brasil, 100 lineas de EP/84 y 3 lineas hibridas de Phaseolus vulgaris x P. acutifolius que mostraban tolerancia a la sequia en la U. de California en Davis, EE.UU. Se iniciaron el Ensayo Internacional de Sequia y Rendimiento del Frijol (EISRF) y el Vivero Internacional de Adaptacion a la Sequia del Frijol (VIASF), para evaluar la tecnica de seleccion actual. Los resultados preliminares confirmaron que los materiales seleccionados en CIAT-Palmira variarian en su tolerancia al estres de sequia en otras localidades; particularmente apreciable es que las mejores lineas y var. en CIAT-Palmira y CIAT-Quilichao (San Cristobal 83 y G 5059) tenian cero rendimientos en CIAT-Popayan, debido principalmente a la pobre adaptacion. En otros ensayos, se estudio la hipotesis de que la tolerancia a la sequia se asocia con la reduccion en la temp. de la cobertura y que este a su vez se asocia con la menor reduccion en la conductancia estomatica y el potencial hidrico de la planta durante periodos de max. estres. Estos resultados se atribuyeron a los materiales tolerantes que extractan una gran cantidad de humedad del suelo, presumiblemente a traves de raices mas profundas. (RA-CIAT) |

| Summary, etc |
In the 2nd growing season of 1984, reduced no. of materials were used to evaluate the present screening strategy and study mechanisms of drought tolerance. The new materials evaluated included 14 lines from the Brazilian national program, 100 lines from EP/84, and 3 Phaseolus vulgaris x P. acutifolius hybrid lines showing drought tolerance at the U. of California at Davis (USA). The Bean International Drought Yield Trial (BIDYT) and the Bean International Drought Adaptation Nursery (BIDAN) were initiated to evaluate the present screening technique. Preliminary results confirmed that materials selected at CIAT-Palmira would vary greatly in tolerance to drought stress at other sites; particularly noteworthy is that the best lines and var. at CIAT-Palmira and CIAT- Quilichao (San Cristobal 83 and G 5059) had zero yields in CIAT- Popayan, primarily due to poor adaptation. In other trials, the hypothesis which associates drought tolerance with reduced canopy temp., and that this in turn is associated with less reduction in stomatal conductance and water plant potential during periods of peak stress, was tested. These results were attributed to tolerant materials extracting a large amount of soil moisture, presumably through deeper roots. (CIAT) |
