“…For these reasons, no or poor reproduction of root-knot nematode may occur during fall cropping of some oat cultivars suitable for nematode reproduction depending on the planting date. Low rates of reproduction of M. incognita and M. arenaria on Tachiibuki were confirmed by a greenhouse assay (Tateishi et al 2011). Also in this field plot study, with Tachiibuki, the Pf/Pi ratios for all planting date treatments were very low.…”

“…Although experimental plots were infested with M. incognita and M. arenaria, each population density was not examined in this study. Considering the low rate of reproduction of M. arenaria on Haeibuki (Tateishi et al 2011), it would appear that M. incognita was mainly responsible for the change in J2 density with this cultivar. Based on 377.0 degree-days required for a generation of the M. incognita Kumamoto population (Iwahori, unpubl.…”

“…Haeibuki is a suitable host for Meloidogyne incognita (Kofoid & White), but neither of the cultivars is a suitable host for M. arenaria (Neal) (Tateishi et al, 2011). We used commercially available seeds (Snow Brand Seed Co. Ltd., Japan) of both cultivars.…”

“…Three Meloidogyne species show no or poor reproduction with Tachiibuki, an oat cultivar suitable for fall cropping, and it has the potential to be utilized as a nematodesuppressive agent (Tateishi et al 2008;Tateishi et al, 2011). Although fall cropping of Tachiibuki planted in early September resulted in the suppression of nematode reproduction in a previous study (Tateishi et al, 2008), the effects of earlier or later planting of this cultivar on such a suppression has not yet been examined.…”

“…Screening for resistance to Meloidogyne spp. in radish ( Teklu et al, 2014 ; O’Neill, 2016 ; Waisen, 2019) and oat ( Tateishi et al, 2011 ; De Brida et al, 2017 ; Uesugi et al, 2018 ) has been investigated and several genotypes (lines) and/or commercial cultivars have been characterized. Research on these crops has led to variable suppression of nematodes, depending upon the plant cultivar and nematode species examined ( Steddom et al, 2008 ; Tateishi et al, 2008 ; Waisen, 2019).…”

Oilseed radish and oat are cool season annual crops that are potentially used as "trap" or "biofumigant" crops for the suppression of plantparasitic nematodes in soil. Cultivars of oilseed radish (Carwoodi, Cardinal, Final, Image, Concorde, Control, Eco-Till, Karakter and Cannavaro), white (Tachiibuki) and black (Pratex) oats were evaluated for their ability to reduce reproduction of three root-knot nematode species: Meloidogyne javanica, M. incognita race 3, and M. arenaria race 1. Nematode penetration and development were also evaluated using selected resistant and susceptible cultivars under greenhouse conditions. Root galling severity, number of eggs per gram of fresh root, and rate of reproduction varied among the cultivars in response to nematode infection. Oilseed radish cv. Carwoodi was resistant to M. javanica, whereas Karakter and Concorde were maintenance hosts allowing the nematode to maintain or increase its population on the plants. For M. incognita, Control and Carwoodi oilseed radish and Tachiibuki oat were resistant hosts. The cultivars that supported little reproduction of M. arenaria were Karakter and Carwoodi radish, and Tachiibuki oat. Comparable numbers of nematodes entered the roots of susceptible and resistant cultivars of oilseed radish and oat during early stages of infection. However, the development of the nematodes as evident from counting young and egg-laying females in roots were significantly decreased or inhibited in the resistant cultivars compared to the susceptible cultivars indicating that resistance occurs at post-infection stages. Histopathological examinations of galled-root tissues also revealed the susceptibility and resistance responses of selected cultivars of oilseed radish and oat to these nematode species.

Solanum torvum, a wild Solanum species, is widely used as a rootstock and is known for its resistance to several pathogens and pests including root‐knot nematode (RKN, Meloidogyne spp.). Virulence to S. torvum was observed in several Meloidogyne species such as M. hapla, but M. hapla populations isolated from Japan have not been tested for parasitism. We performed inoculation assays on S. torvum cultivars and control plants (S. melongena, eggplant; S. lycopersicum, tomato) inoculated with Japanese M. hapla populations, and we then evaluated the host suitability based on the eggmass number. The assays were carried out using nursery plants in small plastic pots. The first assay revealed that S. torvum cultivars that are commercially available in Japan were susceptible to M. hapla. In the second assay, three M. hapla populations obtained from geographically distant areas produced a number of eggmasses on S. torvum roots. The S. torvum cultivars were all resistant to M. incognita, as a control species of Meloidogyne, in both assays. Our examination of the number of eggs per eggmass of M. hapla demonstrated that the values of S. torvum under inoculation of two M. hapla populations were significantly lower than those of S. lycopersicum, implying some difference in the fecundity of M. hapla depending on the host plants. The series of experiments revealed the virulence and reproductivity of Japanese M. hapla populations to S. torvum, posing a potential risk that S. torvum cannot suppress RKN damage in agricultural fields under infestation of such Meloidogyne species.
