Description:	Forage grasses have been included in systems (no-tillage) with crops susceptible to important plant parasitic nematodes (PPNs), but the host status of commercial genotypes is still poorly known. Therefore, the objective of our study was to evaluate the host status of summer forage species to Meloidogyne javanica (Mj) and M. incognita (Mi), under greenhouse conditions. For each interaction, the trials were repeated twice. For this, seedlings were inoculated with an initial population (Ip) of 1,000 specimens (eggs plus second-stage juveniles). After 60—71 days of inoculation, the specimens were extracted from the roots (Fp) to obtain estimates of the reproductive factor (RF=Fp/Ip) and nematodes per gram root (Nema g−1). The species/cultivars tested were Millet ‘ANM 38’, Brachiaria ruziziensis ‘BRS Integra’, B. ruziziensis x B. brizantha ‘BRS RB331 Ipyporã’, B. brizantha ‘BRS Piatã’, Panicum maximum ‘BRS Tamani’, P. maximum ‘BRS Quênia’ and P. maximum ‘BRS Zuri’. All species/cultivars tested were rated as resistant to M. javanica (0≤RF≤0.19; 0≤Nema g−1≤141.44) and M. incognita (0.01≤RF≤0.07; 2.43≤Nema g−1≤66.74). Our study opens the possibility of using these forage species/ cultivars for rotation/succession schedules in areas with infestation by these PPNs.
