Susceptibility Assessments of Tomato Genotypes to Root Knot Nematodes, Meloidogyne javanica
Root-knot nematodes, Meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. The most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. In the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. In the supplementary studie...
متن کاملResistance of Interspecific Arachis Breeding Lines to Meloidogyne javanica and an Undescribed Meloidogyne Species.
Resistance to a peanut-parasitic population of Meloidogyne javanica and an undescribed Meloidogyne sp. in peanut breeding lines selected for resistance to Meloidogyne javanica was examined in greenhouse tests. The interspecific hybrid TxAG-7 was resistant to reproduction of Meloidogyne javanica, M. javanica, and Meloidogyne sp. An Meloidogyne javanica-resistant selection from the second backcro...
متن کاملReaction of citrus rootstocks to Meloidogyne javanica.
The response of Citrus spp. and related rootstocks to a population of Meloidogyne javanica was evaluated in a screenhouse experiment. Palestine and Rangpur lime, rough lemon, sour orange, Sexton and Thentriton tangelo, and Volkamer lemon were not infected by M. javanica. Galls and tip swellings were observed on the roots of Poncirus triloliata and Troyer citrange. There was no evidence of nemat...
متن کاملSuitability of Zucchini and Cucumber Genotypes to Populations of Meloidogyne arenaria, M. incognita, and M. javanica.
The host suitability of five zucchini and three cucumber genotypes to Meloidogyne incognita (MiPM26) and M. javanica (Mj05) was determined in pot experiments in a greenhouse. The number of egg masses (EM) did not differ among the genotypes of zucchini or cucumber, but the eggs/plant and reproduction factor (Rf) did slightly. M. incognita MiPM26 showed lower EM, eggs/plant, and Rf than M. javani...
متن کاملLectin Binding to Meloidogyne javanica Eggs.
T h e egg shell is one of the most impor tant and least understood of the nematode's protective membranes. The egg shell of Meloidogyne incognita consists mostly of proteins (50%), chitin (30%), and traces of lipids and unidentified materials (1). In the present work we used fluorescein isothiocyanate (FITC)-labeled lectins (2) to identify the carbohydrate residues on the gelatinous matr ix and...
