Resumo: Disease resistance, at seedling stage, has been widely used in breeding programs because it is easier to recognize and select. However, the adult-plant resistance (APR) can be used to increase the durability of resistance. An experiment was carried with the cultivars Rio Negro, Rio Tibagi, Diamante Negro, Pérola, Xamego and Aporé, with the objective of identifying APR. Six successive planting dates of these cultivars were madc at seven-day intervals and inoculation with four pathotypes of Colletotrichum lindemuthianum. APR was observed in the cultivars Rio Negro and Rio Tibagi. However, a seedling resistance interferente in the latter was observed. Although the susceptible cultivars Diamante Negro and Pérola showed reduction in symptoms intensity with increase of age, they did not achieve the resistance level of 'Rio Negro' and 'Rio Tibagi'. The cultivars Aporé and Xamego showed seedling resistance to alI four isolates of the pathogen tested.

A resistência, no estádio de plântula, por ser de fácil reconhecimento c seleção, tem sido amplamente utilizada nos programas de melhoramento. Entretanto, a resistência de planta adulta (RPA) pode ser utilizada, visando aumentar a sua durabilidade. Foi conduzido um experimento com os cultivares Rio Negro, Rio Tibagi, Diamante Negro, Pérola, Xamego e Aporé, semeados em seis épocas sucessivas, com intervalo de sete dias e inoculados com quatro patótipos de Colletotrichum lindemuthianum. Foi encontrada resistência de planta adulta nos cultivares Rio Negro e Rio Tibagi; porém, neste último, houve interferência da resistência de plántula. Os cultivares suscetíveis, Diamante Negro e Pérola, embora apresentassem uma redução da intensidade dos sintomas com o aumento da idade, não atingiram o nível de resistência de 'Rio Negro' e 'Rio Tibagi'. Os cultivares Aporé e Xamego apresentaram resistência de plántula aos quatro patótipos do patógeno. Departamento de Diagnóstico e Pesquisa Agropecuária.
