“…Although nematode resistance in general can result from (the combination of) several types of genetic determinant, including major/minor genes and quantitative trait loci (QTLs), RKN resistance in solanaceous crops is mainly dominant and conferred by single major dominant genes (supporting information Table S1). In addition, one recessive gene has been hypothesised in the pepper cultivar ‘Carolina Wonder’, associated with the dominant R gene named N . Very recently, four QTLs have also been identified in pepper (see detailed discussion below).…”

“…For example, even though at least nine R genes for RKN resistance have been identified in wild tomato and more than ten in wild pepper accessions, only two of them are widely available in commercial varieties, i.e. Mi‐1.2 and N in tomato and pepper respectively . In some instances, however, this process can be considerably accelerated by using molecular markers linked to the R gene of interest, and marker‐assisted selection (MAS) has been estimated to reduce the time to market by 50–70% .…”

Host genetic resistance to root-knot nematodes,Meloidogynespp., in Solanaceae: from genes to the field

Root-knot nematodes (RKNs) heavily damage most solanaceous crops worldwide. Fortunately, major resistance genes are available in a number of plant species, and their use provides a safe and economically relevant strategy for RKN control. From a structural point of view, these genes often harbour NBS-LRR motifs (i.e. a nucleotide binding site and a leucine rich repeat region near the carboxy terminus) and are organised in syntenic clusters in solanaceous genomes. Their introgression from wild to cultivated plants remains a challenge for breeders, although facilitated by marker-assisted selection. As shown with other pathosystems, the genetic background into which the resistance genes are introgressed is of prime importance to both the expression of the resistance and its durability, as exemplified by the recent discovery of quantitative trait loci conferring quantitative resistance to RKNs in pepper. The deployment of resistance genes at a large scale may result in the emergence and spread of virulent nematode populations able to overcome them, as already reported in tomato and pepper. Therefore, careful management of the resistance genes available in solanaceous crops is crucial to avoid significant reduction in the duration of RKN genetic control in the field. From that perspective, only rational management combining breeding and cultivation practices will allow the design and implementation of innovative, sustainable crop production systems that protect the resistance genes and maintain their durability.

“…RAPD markers were used to identify polymorphism between three genotypes under study as it used by Klein -Lankburst et al (1992). The cultivars of tomato were screened by RAPD-PCR to examine resistance or tolerance to root-knot nematode M. incognita (Fery and Thies, 1997;Fery et al, 1998).…”

This study was carried out to determine the nematicidal efficiency of seven bionematicides (Nema end, Nema cont, Nema clean, Nema K, Bio-zeid, Bio-arc and Nemex) compared with one nematicide (Nemacur 10%) on three cultivars of tomato against the root-knot nematode (RKN) Meloidogyne incognita under greenhouse conditions. The screened tomato cultivars (endless summer, supermarmand and jueblle) were significantly different in their response to nematode infection. Detectable tolerance to nematode infection was recorded with cultivar Endless summer and Juebelle while the least tolerance was recorded with supermarmand cultivar. Number of galls and egg masses were significantly decreased in the investigated cultivars treated with Nemacur, and Nema k,

“…2A was, unexpectedly, heterogeneous for reaction to M. arenaria race 1. Based on our extensive use of 'California Wonder' as a susceptible control in numerous M. incognita studies in recent years, it is unlikely that the resistance observed in this 'California Wonder' population to M. arenaria race 1 is due to the N gene reported to condition resistance to M. incognita in C. annuum (Fery and Dukes., 1996;Fery et al, 1998).…”

Greenhouse experiments determined the inheritance of resistance to the peanut root-knot nematode [Meloidogyne arenaria (Neal) Chitwood race 1] in Capsicum chinense Jacq. germplasm lines PA-353 and PA-426. Evaluation of parental, F1, F2, and backcross populations of the crosses PA-353 × PA-350 and PA-426 × PA-350 (PA-350 is a susceptible cultigen) indicated that resistance in both C. chinense germplasm lines was conditioned by a single dominant gene. Evaluation of the F1 × resistant parent backcross populations in the cytoplasm of their respective resistant and susceptible parents indicated that the cytoplasm of the resistant parent is not needed for full expression of resistance. Allelism tests indicated that the dominant resistance gene in both PA-353 and PA-426 is allelic to a resistance gene in C. annuum L. `Carolina Cayenne'. However, these allelism tests did not demonstrate conclusively that the M. arenaria race 1 resistance gene in C. chinense is the N gene that conditions resistance to the southern root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood] in C. annuum. The ease and reliability of evaluating plants for resistance to root-knot nematodes and the availability of simply inherited sources of resistance makes breeding for peanut root-knot nematode resistance a viable objective in C. chinense breeding programs.
