Resumo
Objetivou-se, neste trabalho, identificar progênies de Coffea arabica cv. IPR 100 com resistência ao nematóide Meloidogyne incognita raça 1. O experimento foi conduzido em casa de vegetação (Londrina, PR, Brasil) no delineamento em blocos ao acaso com 3 repetições e parcelas com 15 plantas. Foram avaliadas seis progênies da cultivar IPR 100 e a cultivar Mundo Novo IAC 376-4 foi utilizada como padrão suscetível. Foram inoculados 500 ovos por planta, totalizando 7500 ovos por parcela de 150 cm 2 . Foi avaliado o número de galhas e massas de ovos presentes nas raízes. As seis progênies da cultivar IPR 100 foram mais resistentes ao M. incognita raça 1 do que o padrão suscetível.
The objective of this study was to identify progenies of Coffea arabica cv. IPR 100 with resistance to nematode Meloidogyne incognita race 1. The experiment was performed in greenhouse (Londrina, PR, Brazil) with an experimental design of randomized blocks with 3 replications and 15 plants per plot. Six progenies of cultivar IPR 100 were evaluated, and Mundo Novo IAC 376-4 cultivar was used as susceptible control. Five hundred eggs per plant were inoculated, totalizing 7500 eggs per plot of 150 cm 2 . The number of galls and egg masses in the roots were evaluated. All progenies of cultivar IPR 100 presented more resistance to M. incognita race 1 than the susceptible control.
