Productivity of dry bean lines (Phaseolus vulgaris) resistant to the anthracnose fungus (Colletotrichum lindemuthianum)

brag Bragantia Bragantia 0006-8705 1678-4499 Instituto Agronômico de Campinas Campinas, SP, Brazil With the objective of knowing the yielding ability of dry bean lines of Preto, Diversos and Chumbinho groups resistant to the anthracnose agent, trials in randomized complete-block design were carried out in the Main Experimental Station of Campinas in the rainy season of 1977, 1978 and 1979. 'Carioca', 'Moruna' and 'Aroana' were used as controls for lines of Diversos, Preto and Chumbinho groups, respectively. The results showed that the lines 5-9-4-3-1-4, 5-9-4-3-1-5, 18-1-6 and 5-9-4-3-1-6, with mean yields of 2,100, 2,079, 2,055 and 2,028 kg/ha were superior to the control Moruna, which yielded 1,580 kg/ha, at 5% level. None of Chumbinho lines outyielded Aroana although high mean yield was obtained by 5-1-1-5-1-9 with 2,336 kg/ha compared with 2,136 kg/ha got by the control. On the other hand, the lines 10-3-1 and 10-6-2 with means of 3,133 and 2,823 kg/ha outyielded Carioca which obtained 2,375 and 2,355 kg/ha, respectively. The effect of year was significant in 11 out of the 12 groups of experiments while the interaction treatment x year was observed in two of them. The best lines will be included in the regional trials and seeds of some of them increased in large quantities for releasing to the growers of Campinas region. ARTIGOS Avaliação da produtividade de linhagens de feijoeiro resistentes ao fungo da antracnose Productivity of dry bean lines (Phaseolus vulgaris) resistant to the anthracnose fungus (Colletotrichum lindemuthianum) Antonio Sidney Pompeu Seção de Genética, Instituto Agronômico, IAC RESUMO A capacidade produtiva de linhagens de feijoeiro (Phaseolus vulgaris) resistentes ao fungo da antracnose (Colletotrichum lindemuthianum) pertencentes aos grupos Preto, Chumbinho e Diversas, foi estimada em experimentos em blocos ao acaso, instalados em Campinas, no cultivo das águas de 1977, 1978 e 1979. Utilizaram-se os cultivares Moruna, Aroana e Carioca como controles para as linhagens dos grupos Preto, Chumbinho e Diversos respectivamente. Pela análise estatística dos dados obtidos pelas linhagens do grupo Preto, comuns aos ensaios de 1977 e 1978, 1978 e 1979, observou-se que as de prefixos 5-9-4-3-1-4, 5-9-4-3-1-5, 18-1-6 e 5-9-4-3-1-6, com médias de 2.100, 2.079, 2.055 e 2.028kg/ha, foram superiores ao 'Moruna', que produziu 1.580kg/ha. No grupo Chumbinho, cujas linhagens foram avaliadas em 1978 e 1979, a de prefixo 5-1-1-5-1-9, com 2.336kg/ha, destacou-se das demais, embora esta produtividade média estivesse ao mesmo nível, estatisticamente, da verificada para o 'Aroana', 2.136kg/ha. Para as linhagens do grupo Diversos, estudadas em 1978 e 1979, apenas 10-3-1 e 10-6-2, com produções médias de 3.133 e 2.823kg/ha, foram superiores, respectivamente, a 2.375 e 2.355kg/ha, observadas para o 'Carioca'. Outras linhagens deste grupo tiveram médias acima do controle, como 10-9-2, 10-9-1 e 10-5-1, com 2.698, 2.686 e 2.649kg/ha (Carioca – 2.355kg/ha) na ausência do patógeno. Nas análises conjuntas foram notados efeitos significativos para ano em onze dos doze grupos de experimentos e em apenas dois para a interação tratamento x ano. As melhores linhagens serão colocadas nos ensaios regionais e algumas terão suas sementes aumentadas e colocadas à disposição dos agricultores da região de Campinas.
