Resistance of Peach and Plum Rootstocks from Spain, France, and Italy to Rootknot Nematode Meloidogyne javanica
Two trials involving 20 Prunus rootstocks were conducted under greenhouse conditions to screen for resistance to root-knot nematode [Meloidogyne javanica (Treub.) Chitwood]. Many of the tested materials are interspecific hybrid rootstocks and represent new commercial peach (P. persica Batsch) and plum (Prunus sp.) releases or experimental genotypes of Spanish, French, and Italian origin. In the...
متن کاملEffect of chitosan on root-knot nematode, Meloidogyne javanica
In our study two different chitosan with low and high molecular weight at different dilutions i.e. standard, 1:1, 1:2, 1:3, 1:4, 1:5 and 1:10 were evaluated against root-knot nematode, Meloidogyne javanica in vitro and in vivo under greenhouse conditions. In vitro results revealed that both chitosan with all used concentrations significantly reduced the egg hatching when compared to control. No...
متن کاملInheritance of resistance to the root-knot nematode Meloidogyne javanica in lettuce.
Resistance to the root-knot nematodes Meloidogyne spp. would be a valuable attribute of lettuce Lactuca sativa L. cultivars grown in tropical regions. The looseleaf lettuce 'Grand Rapids' is resistant to both M. incognita and M. javanica. Resistance to M. incognita has a high heritability, under the control of a single gene locus, in which the 'Grand Rapids' allele, responsible for resistance (...
متن کاملResistance assessment of grapevine rootstocks used in Chile to the root-knot nematodes Meloidogyne ethiopica, M. hapla, and M. javanica
E. Aballay, and O. Vilches. 2015. Resistance assessment of grapevine rootstocks used in Chile to the root-knot nematodes Meloidogyne ethiopica, M. hapla, and M. javanica. Cien. Inv. Agr. 42(3): 407-413. The rootstocks 1103 P, 101-14, K 5BB, SO4, and 3309 were assessed to determine their resistance to the three common Meloidogyne species present in Chilean vineyards, M. ethiopica, the most frequ...
متن کاملReaction of Pigeonpea Cultivars and Germplasm Accessions to the Root-knot Nematode, Meloidogyne javanica.
Meloidogyne javanica is an important nematode pest of pigeonpea. Thirty-four pigeonpea cultivars and 227 germplasm accessions were evaluated for resistance to M. javanica based on number of galls, egg masses, size of galls, and area of root covered with galls. Galls were not formed on 75% of the cultivars, and no egg masses were observed on the roots of four cultivars (UPAS 120, Pant A3, CO 1, ...
