Root-knot nematode resistance of F progeny of an intraspecific hybrid (Lycopersicon peruvianum var. glandulosum Acc. No. 126443 x L. peruvianum Acc. No. 270435), L. esculentum cv. Piersol (possessing resistance gene Mi), and L. esculentum cv. St. Pierre (susceptible) was compared. Resistance to 1) isolates of two Meloidogyne incognita populations artificially selected for parasitism on tomato p...

The study was carried out to investigate plant parasitic nematodes in oil rose growing areas Isparta province July-August 2022. Soil samples were taken from 15 different and the with 65 samples. A total of 12 species determined study. These are Tylenchus spp., Aphelenchus Pratylenchus Dictylenchus Dorylaimus Paratylenchus Longidorus Xiphinema Meloidogyne Helicotylenchus spp. Merlinus (52.3%), (...

Proteins and various isozymes were investigated by direct analysis of single specimens in order to check molecular genetic variability, which is not rare in Meloidogyne species in spite of parthenogenetic reproduction. Variability was found in esterases, ocglycerophosphate, malate dehydrogenases, and some other proteins. Other loci appear monomorphic in the genus (for example, catalase), Distin...

Rhizobacteria has shown promising results in managing nematodes and improving the root system of banana plants. However, their effects on commercial plants different generations remain unclear. In this study performed under field experiment, we evaluated effect three types (injection, edaphic foliar) a local rhizobacterial consortium application root, nematode populations, damage third-generati...

Identification of species of Meloidogyne Goeldi, 1887 is fi-equently accomplished by using perineal patterns and morphometrics, but intraspecific populations are not easily distinguished. Chromosome numbers have been determined for 10 (6) of the 36 species of Meloidogyne which are currently recognized (1, 5). Four of these species have a range of chromosome numbers. This chromosome range permit...

During sampling of several Coffea arabica plantations in Tanzania severe root galling, caused by a root-knot nematode was observed. From pure cultures, morphology and morphometrics of juveniles and females matched perfectly with Meloidogyne africana, whereas morphology of the males matched identically with those of Meloidogyne decalineata. Based on their Cox1 sequence, however, the recovered ju...
