Reaction of common bean genotypes to Meloidogyne incognita Race 1

Reaction of common bean genotypes to Meloidogyne incognita Race 1

ABSTRACT The objective was to determine the reaction of 33 Phaseolus vulgaris L. genotypes to parasitism by Meloidogyne incognita race 1. The genotypes used in this study six included commercially exploited ("IAPAR­- 81", "EL- 22", "Carioca", "Serrano", "BATT- 477" and "Uirapuru") varieties, one susceptible ("Rico- 23") and two resistant ("Aporé" and "Pérola") varieties; the others were provided by farmers of the South of Espírito Santo State. The experiment was carried out in a greenhouse in a completely randomized design with 7 replicates. The plants were inoculated with 4,000 eggs + second-stage juveniles (J2) of nematodes. After 50 days, the final population of nematodes (FP), reproduction factor (RF) and percentage reproduction rate (%RR) were evaluated. The resistance selection was based on the %RR, i.e., 0-25% = highly susceptible (HS); 26-50% = susceptible (SU); 51-75% = little resistant (LR); 76-95% = moderately resistant (MR); 96-99% = resistant (RE); 100% = highly resistant (HR) or immune (IM). Only the genotype "Preto Meia Lua" was highly resistant. The genotypes "Terrinha- 2" and "Mulatinho" were classified as resistant, "EL- 22", "BATT- 477", "Vermelho", "Bate Estrada" and "Paina" as (susceptible) and genotypes "Rico 23" and "Morgado" as highly susceptible.
