Abstract
Earlier field trials indicated that certain plum rootstocks—Marianna 2623, Marianna 2624, and Myrobalan 29—are resistant to the one species of root-knot nematode recognized at the time the work was done. However, since then several species of root-knot nematodes have been classified. Two of these species—Meloidogyne incognita var. acrita and M. javanica—are known to cause serious trouble in California orchards, so additional work was necessary to find out if the rootstocks are resistant to both species.
