Caracterización fenotípica por resistencia a sequía terminal de germoplasma de frijol común
Terminal drought is a worldwide constraint to common bean production and its negative effects will be increased by climate change. The objective of this research was to characterize phenotypically advanced lines and commercial cultivars of common bean for their resistance to terminal drought stress....

| description | Terminal drought is a worldwide constraint to common bean production and its negative effects will be increased by climate change. The objective of this research was to characterize phenotypically advanced lines and commercial cultivars of common bean for their resistance to terminal drought stress. Field trials were conducted during 2012 and 2013 at Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia. A 4x4 partially balanced lattice design with four replicates was used and, evaluated under irrigation and terminal drought. To achieve the terminal drought condition, irrigation was suspended at 22-23 days after planting. Terminal drought reduced mean grain yield by 68%. Lines SEN 56, BFS 29, NCB 226 and SER 16 showed high grain yield in both irrigated (3617-3836 kg/ ha) and terminal drought (1232-1447 kg/ha) conditions, while RCB 593 and G 40001 showed high grain yield in drought (>1270 kg/ha) and similar to checks in irrigated condition. The most resistant lines showed lower drought susceptibility index (0,88 - 1,00), earlier maturity (56 - 60 dds), superior geometric mean (1931 - 2311 kg/ha), and higher number of grains/m2, (673 - 1250). Drought resistant lines produced at least 15% and 50% more grain yield than EAP 9510-77, commercial check for Central America, in irrigated and drought condition, respectively. In addition, they were also superior to other commercial checks such as DOR 390 and Bribri. |

La sequía terminal es una limitante mundial para la producción de frijol y se acentuará por efecto del cambio climático. El objetivo de este estudio fue caracterizar fenotípicamente líneas avanzadas y germoplasma comercial de frijol por su resistencia a sequía terminal. La investigación se realizó durante el 2012 y 2013 en el Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia; bajo riego y sequía terminal. Se utilizó un látice 4x4 parcialmente balanceado con cuatro repeticiones. Para lograr la condición de sequía terminal, el riego se suspendió a los 22-23 días después de la siembra. La sequía terminal redujo, en promedio, un 68% el rendimiento. Las líneas SEN 56, BFS 29, NCB 226 y SER 16, mostraron alto rendimiento en riego (3617-3836 kg/ha) y en sequía terminal (1232-1447 kg/ha), mientras que las líneas RCB 593 y G 40001 mostraron alto rendimiento (>1270 kg/ha) en sequía terminal y similar al de los testigos bajo riego. Las líneas más resistentes mostraron menores índices de susceptibilidad a sequía (0,88 - 1,00), aceleración de la madurez (56 - 60 dds), media geométrica superior (1931 - 2311 kg/ha) y mayor número de granos/m2 (673 - 1250). Las líneas más resistentes obtuvieron al menos un 15 y 50% más de rendimiento en riego y sequía terminal, respectivamente, que EAP 9510-77, testigo comercial para Centroamérica. Además, superaron a otros testigos comerciales como DOR 390 y Bribrí. 2018-01 2018-01-10T18:36:27Z 2018-01-10T18:36:27Z Journal Article https://hdl.handle.net/10568/89976 es Open Access application/pdf Universidad de Costa Rica Chaves-Barrantes, Néstor Felipe; Polanía, José A.; Muñoz-Perea, Carlos Germán; Rao, Idupulapati M.; Beebe, Stephen E.. 2018.
