| Description | The yield of South African bean lines was assessed in Malawi, using 3 groups with 15 genotypes each. In the 1st trial, carried out in 4 different agroecological zones, Carioca 80 was the best genotype with high yields at all sites (712-1768 kg/ha) and resistant to angular leaf spot and rust. Other genotypes performed well at several sites: BAT 1514, PVBZ 1782, PVA 340, PVA 773, PVA 262, PVBZ 1589, and PVBZ 1713. Highest yields were obtained in Dedza (av. 1523 kg/ha) and the lowest in Matapwata (av. 276 kg/ha). BAT 1514, PVBZ 1589, and PVBZ 1782 were also resistant to angular leaf spot and rust in Champhira and Lunyangwa. All cv. were susceptible to floury leaf spot. In the 2nd trial, also conducted at 4 different sites, the highest yields (av. 889 kg/ha) and the greatest resistance to angular leaf spot (av. 1.7) were obtained in Mzimba. The best South African genotypes were Umvoti, Kompasberg, H 7822-C2, PC 222-5-D2, PC 166-C39, and Enselini. Seed size was generally large in Champhira, with 100-seed wt. of 52 g. All genotypes were susceptible to angular leaf spot and rust, but several were resistant to Ascochyta in Bunda. In the 3rd trial, carried out in Bunda, local genotype Nyauzembe had the highest production (1016 kg/ha), followed by the South African lines PC 213- C3, Umvoti, Type 2 White, PC 167-C6, and PC 351-19 (772, 740, 671, 731, and 647 kg/ha, resp.). Generally all the South African lines had small seeds and high susceptibility to rust. (CIAT) Se evaluo el rendimiento de lineas de frijol sudafricanas en Malawi, utilizando 3 grupos con 15 genotipos cada uno. En el primer ensayo, realizado en 4 zonas agroecologicas diferentes, el mejor genotipo fue Carioca 80 con altos rendimientos en todos los sitios (712-1768 kg/ha), con resistencia a mancha foliar angular y roya. Otros genotipos presentaron un buen desempeno en varios de los sitios: BAT 1514, PVBZ 1782, PVA 340, PVA 773, PVA 262, PVBZ 1589, PVBZ 1713. Los mayores rendimientos se obtuvieron en Dedza (prom. 1523 kg/ha) y los mas bajos en Matapwata (prom. 276 kg/ha). BAT 1514, PVBZ 1589 y PVBZ 1782 tambien presentaron resistencia a mancha foliar angular y roya en Champhira y Lunyangwa. Todos los cv. fueron susceptibles a la mancha harinosa de la hoja. En el segundo ensayo, tambien realizado en 4 sitios diferentes, se obtuvieron las producciones mas altas (prom. 889 kg/ha) y la mayor resistencia a mancha foliar angular (prom. 1.7) en Mzimba. Los mejores genotipos sudafricanos fueron Umvoti, Kompasberg, H 7822- C2, PC 222-5-D2, PC 166-C39 y Enselini. El tamano de semilla fue generalmente grande en Champhira, alcanzando medidas hasta de 52 g/100 semillas. Todos los genotipos fueron susceptibles a mancha foliar y roya, pero algunos fueron resistentes a Ascochyta en Bunda. En el tercer ensayo, realizado en Bunda, el genotipos local Nyauzembe tuvo la mayor produccion (1016 kg/ha) seguido de las lineas sudafricanas PC 213-C3, Umvoti, Type 2 White, PC 167-C6 y PC 351-19 (772, 740, 671, 731 y 647 kg/ha, resp.). Generalmente todas las lineas sudafricanas presentaron semillas pequenas y alta susceptibilidad a la roya. (CIAT) |
