| Description | Two trials were conducted to screen germplasm for heat and drought tolerance. In the 1st, the performance of 25 genotypes under terminal drought stress was assessed. Lines A344, A268, A286, BAT 336, A442, BAT 477, Umvoti, and Domino were high-yielding (811, 750, 713, 717, 665, 659, 608, and 667 kg/ha, resp.) and heat- and drought-tolerant; the 1st 4 genotypes were also resistant to angular leaf spot and rust. In the 2nd trial, the performance of genotypes from North and South America and Central and Southern Africa under controlled drought stress was evaluated. Outstanding performance of Sapelekedwa and 8-7 was confirmed. In another trial to assess the performance of promising cv. identified under drought conditions in Ethiopia and Latin America, BAT 1198, V 8025, G 5059, Mexican 142, and Ex Rico 23 were the top 5 high-yielding lines. Genotypes from the Malawian germplasm collection were also evaluated under soil moisture conditions. Lines 6-1, 8-7, and 25-2 outyielded the rest (yields up to 808 kg/ha); they also had large no. of pods/plot and proved to be very tolerant to drought conditions. (CIAT) Se realizaron 2 ensayos para seleccionar germoplasma por tolerancia al calor y a la sequia. En el primero, se evaluo el desempeno de 25 genotipos a estres de sequia terminal. Los genotipos con las producciones mas altas (kg/ha), tolerantes a calor y sequia, fueron A344 (811), A268 (750), A286 (713), BAT 336 (717), A442 (665), BAT 477 (659), Umvoti (608) y Domino (667); los primeros 4 genotipos tambien fueron resistentes a la mancha foliar angular y roya. En el segundo ensayo, se evaluo el desempeno de genotipos de America del Norte y del Sur y del centro y sur de Africa en condiciones controladas de estres de sequia. Se confirmo un excelente desempeno de Sapelekedwa y 8-7. En otro ensayo para evaluar el desempeno de cv. promisorios identificados en condiciones de sequia en Etiopia y America Latina, se destacaron por su mayor produccion las lineas BAT 1198, V 8025, G 5059, Mexican 142 y Ex Rico 23. Tambien se evaluaron genotipos del germoplasma de Malawi en condiciones de estres por sequia. Los mejores fueron 6-1, 8-7 y 25-2, con rendimientos hasta de 808 kg/ha, gran no. de vainas/parcela y muy tolerantes a las condiciones de sequia. (CIAT) |
