Host status of soybean genotypes to Meloidogyne species

Reação de genótipos de soja a espécies de Meloidogyne

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT:

This study aimed to evaluate the host status of soybean genotypes to Meloidogyne javanica (Est J3), Meloidogyne sp.0 (Est R0), and M. graminicola (Est VS1). In the first experiment, all tested genotypes (BMX Potência RR, BMX Valente RR, BMX Icone IPRO, PELBR10-6049 RR, and TECIRGA 6070 RR) were susceptible to M. javanica, with reproduction factor (RF) >1.0, and resistant to Meloidogyne sp.0 (0.01 > RF < 0.15), whereas in the second experiment, all genotypes (BRS 246 RR, PELBR11-6038 RR, PELBR11-6001 RR, PELBR10-6005 RR, BMX Apolo RR, PELBR11-6028 RR, PF11651, PF103251, PELBR11-6035 RR, PELBR10-6050 RR, PELBR11-6042 RR, PELBR10-6017 RR, PELBR11-6007 RR, PELBR10-6016 RR, and PELBR10-6049 RR) were resistant to M. graminicola (0.06 > RF < 0.43).

Key words:
