Abstract
This investigation was carried out in two successive seasons (2021 and 2022) on one – year – old six grape rootstocks: Freedom, Harmony, Salt Greek, Teleki, SO4 and Richter. These rootstocks were evaluated for resistance to different inoculum levels of MELOIDOGYNE INCOGNITA i.e. 1000, 2000, 3000, 4000 and 5000 J2 /pot. The different rootstocks were left out; plant, root and soil were examined at the end of the two seasons. Results indicated the superiority of Harmony and Freedom rootstocks than the other four rootstocks. These rootstocks are characterized by: vigorous vegetative growth, larger root system density with longest and better fine, medium and large roots distribution. Moreover, the rootstocks had higher leaf petioles content of N, P and K. Also data of nematode parameters showed that, number of nematode in soil, number of females, egg-masses/ root system and eggs / eggs-mass, rate of build-up and numbers of galls. Results revealed that all nematode parameters were significantly increased as the inoculum levels of nematode increased from 1000 to 5000 J2. In addition, both Harmony and Freedom gave the lowest nematode population in soil and roots, rate of nematode build-up and number of galls/root (most resistant rootstocks), while, Salt Greek and Teleki were (moderately resistant). On the other hand, SO4 and Richter were the most susceptible rootstocks to M. incognita. Generally, both Harmony and Freedom rootstocks can be recommended for controlling root knot nematode M. incognita A in Egypt.
