KANAYAMA, Fabio Seidi et al. Progenies of Coffea arabica cv. IPR 100 with resistance to nematode Meloidogyne incognita race 1. Ciênc. agrotec. [online]. 2009, vol.33, n.5, pp. 1321-1326. ISSN 1981-1829. http://dx.doi.org/10.1590/S1413-70542009000500018.
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 cm2. 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.
