Time Point

Phaseollin accumulated locally at point-freezing injuries on hypocotyls of intact etiolated seedlings of Phaseolus vulgaris. Maximum amounts occurred within 24 to 30 h after injury. Smaller amounts accumulated at similar sites on hypocotyls excised at the time point-freezing injuries were made, and the accumulation was less localized. Increasing amounts of phaseollin occurred at sites increasingly distant from the cotyledonary nodes in both intact and excised hypocotyls. Much higher levels of phaseollin were elicited by excision per se than by point-freezing. Phaseollin was not detected after freezing of whole hypocotyls, indicating that living tissue adjacent to injuries is required for accumulation. The data are discussed in relation to host–parasite specificity, with particular reference to the interaction between P. vulgaris and Colletotrichum lindemuthianum.

Germ Tube Elongation

Germination of conidia in cultures of the beta and gamma races of Colletotrichum lindemuthianum growing on bean juice agar was delayed in 15% CO2, though the proportion of conidia that finally germinated under these conditions was similar to the proportion that germinated in cultures maintained in air. Germ tube elongation in CO2 was inhibited during the early stages of development, but vegetative growth was ultimately stimulated under these conditions. Sporulation of cultures maintained in CO2 was delayed and fewer conidia were formed than in cultures maintained in air.The results suggest that there is an interrelationship between vegetative growth and spore production. The implications of these results to previous work on the effects of 15% CO2 on the host–parasite interaction between C. lindemuthianum and Phaseolus vulgaris are discussed.

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.

O trabalho foi realizado com o objetivo de verificar se as famílias de feijão (Phaseolus vulgaris L.) com maior produtividade de grãos são as que possuem maior resistência ao Colletotrichum lindemuthianum e, assim, poder utilizar a produtividade de grãos como critério auxiliar na seleção de linhagens mais resistentes. Para isso, foram realizados cruzamentos entre as linhagens AN 730340, AN 910522, AN 910523 e AN 910546, resistentes ao patógeno, com a cultivar Carioca, que é suscetível. A partir da geração F2, as populações foram avançadas em dois locais no sul de Minas Gerais, Lavras e Lambari, sendo selecionadas 100 plantas resistentes (sem sintomas) e 100 suscetíveis (com alta severidade da doença), formando, assim, duas subpopulações por cruzamento em cada local. Essas populações foram conduzidas em "bulk" até a geração F5. Cinqüenta plantas F5 deram origem às famílias F5:6 e, posteriormente, 21 famílias F5:7, que foram avaliadas com relação à produtividade de grãos e severidade do patógeno nos dois locais. Constatou-se que, especialmente sob alta severidade da doença, a produtividade de grãos foi um ótimo critério seletivo para identificação de famílias resistentes.

Colletotrichum lindemuthianum, the causal pathogen of common bean (Phaseolus vulgaris) anthracnose, is highly variable. Therefore, understanding its race structure and identification of new sources of resistance is necessary for the development of varieties with durable resistance. The objectives of this study were (i) to characterize isolates of C. lindemuthianum collected from three major bean-growing regions in Zambia, and (ii) evaluate the CIAT Phaseolus core collection for resistance to C. lindemuthianum races 37, 73, and 566, and a blend of 20 races. Isolates collected from three major bean-growing districts in Zambia, namely Mporokoso, Mpika, and Mbala, were characterized as race 37, 73, and 566, respectively. A subset of the CIAT core collection comprised of 885 accessions of common bean, 13 accessions of scarlet runner bean (P. coccineus), and 11 accessions of year bean (P. dumosus) were evaluated for resistance to races 37, 73 and 566, and a blend of 20 races in a greenhouse at University of Zambia, Lusaka, Zambia. A total of 72%, 66%, 48% and 9% of P. vulgaris accessions evaluated were highly resistant to races 37, 73, 566 and a blend of 20 races, respectively. Also, accessions of P. coccineus and P. dumosus, highly resistant to races 37, 73 and 566, were identified. Only eight of the 331 P. vulgaris accessions were highly resistant to all three individual races (37, 73, and 566) and to a blend of 20 races. These eight accessions constitute a valuable breeding resource for developing varieties with durable resistance to C. lindemuthianum.
