Abstract

The reaction of peach and nectarine rootstocks, Garnem, Cadaman, GF 677, Barrier, Nemaguard and M-29, used in Turkey was investigated to five populations of root knot nematode species, Meloidogyne incognita (Kofoid & White, 1919) and Meloidogyne javanica (Treub, 1885), under controlled conditions. The study was conducted at the Plant Protection Central Research Institute of the Laboratory of Nematology (Republic of Turkey Ministry of Agriculture and Forestry) in 2013-2016. Three M. javanica (TR16-2, TR12-1 and S5-1) and two M. incognita (TR10-3, S4-1) populations were obtained from infested peach orchards and established pure culture. All rootstocks were inoculated with 3000 second stage juveniles (J2s) from each a population. Each combination was replicated five times. One hundred and twenty d after inoculation, the ratio of galling on the roots and the number of nematode J2s in the soil were assessed and thus the response of rootstocks was determined. M-29, Cadaman and Garnem rootstocks were resistant to all populations, whereas GF 677 was susceptible to all populations. Nemaguard was resistant to TR16-2 and TR12-1 populations, but this rootstock was susceptible to S5-1, TR10-3 and S4-1 populations. Barrier rootstock was moderately resistant to TR16-2 and TR12 populations but susceptible to S5-1 and S4-1 populations. The findings could be used for control root-knot nematodes as well in breeding programs.
