“…Recent cloning of this gene revealed that it encodes a member of the plant resistance protein family characterized by the presence of a putative nucleotide binding site and a leucine-rich repeat. Brown et al (1996) used QTL analysis confirmed supports a genetic model equivalent to monogenic dominant control.…”

The inheritance pattern of resistant tomato to root-knot nematode was studied.GM2 accession and Gondol Putih (GP) cultivars were used as resistant and susceptible parent, respectively. Parental plants, F1 generation, and the F2 generation were grown individually in the sterile soil.One thousands of larvae stage 2 (L2) nematode of M. incognitawas infested in each plant. Data of root gall intensity, the number of egg mass, population of L2 nematodes in root and soil were analyzed with the KormogorovSmirnov's test, Chi-square test, and potence ratio. The F2 selected resistant plantsthen were grown and self fertilizedto identify of homozygote plants (F2) related to nematode resistant and good fruit characters.The result showed that the resistant to root-knot nematode was controlled by a dominant gene. Positive correlation between damage levels of roots, eggs mass number and L2 larvae population in the root was significant. Eleven selected plants,conferredthe homozygous resistant gene, was prospective lines to be used pedigree or single seed descent selection in producing variety with resistant to nematode, high yield and quality of fruit.

“…They were inherited in the dihaploid population where segregation was also detected. Isozyme and molecular markers may be usefully employed to follow and accelerate the introgression of traits of interest from S. aethiopicum into eggplant, as has been demonstrated in other Solanaceae (Brown et al 1996;Fulton et al 1997).…”

Androgenic dihaploids from somatic hybrids between Solanum melongena and S. aethiopicum group gilo as a source of resistance to Fusarium oxysporum f. sp. melongenae

et al. 2002

Dihaploid plants were obtained through anther culture of somatic hybrids between eggplant and Solanum aethiopicum gilo. The androgenic origin of the dihaploids was demonstrated by ploidy determination (flow cytometry and chloroplast counting) and isozyme and molecular (I-SSR and RAPDs) analyses. The androgenic plants showed significant morphological variability in the traits analysed. Pollen viability in the diploid androgenic plants was drastically reduced with respect to the somatic hybrids; however most of the dihaploids produced parthenocarpic fruits. S. aethiopicum and the somatic hybrids showed complete resistance to fungal wilt caused by Fusarium oxysporum f. sp. melongenae. Out of the 41 dihaploids inoculated, 34 were symptomless. The population of androgenic plants developed may represent a useful source for introgression of the Fusarium resistance trait into eggplant.

“…(5,6,18). Resistance to M. chitwoodi has been transferred from a resistant genotype of S. bulbocastanum to the gene pool of the cultivated potato by somatic hybridization (1,7), and a single gene has been localized on chromosome 11 that appears to control this resistance (8). Also, various levels of resistance to M. hapla have been reported (9,15,18).…”

Van der Beek, J. G., Poleij, L. M., Zijlstra, C., Janssen, R., and Janssen, G. J. W. 1998 The root-knot nematode species Meloidogyne chitwoodi Golden et al. and M. hapla Chitwood can cause growth and yield reductions and quality loss in a large number of crops. In potato (Solanum tuberosum L.), these root-knot nematodes are able to reproduce on roots, causing yield reduction (21). M. fallax Karssen, which was described recently (22), is allopatric with M. chitwoodi in the Netherlands, and its host range is similar to that of M. chitwoodi. M. hapla causes little quality damage due to gall formation on the outside of tubers, in contrast to M. chitwoodi (7). Recent observations indicate that M. chitwoodi and M. fallax reproduce similarly on tubers, and both result in quality loss (J. G. van der Beek, unpublished data). In addition to yield reduction and quality loss, an increase in the nematode population due to cultivation of a susceptible host makes these pathogens a potential threat to agriculture in Western Europe, because many crops in the current rotation schemes are good hosts (33). However, M. hapla does not reproduce on monocotyledonous crops, which may be used in rotation with dicotyledons as an effective control measure.The introduction of resistant potato cultivars also would improve the efficiency of crop rotation in reducing this threat. However, in current potato cultivars, no desirable level of resistance to M. chitwoodi and M. hapla has been identified (7,17).Thus far, intraspecific variation in M. chitwoodi has been described by the occurrence of three host races that can be distinguished on alfalfa cv. Thor (nonhost for race 1 and host for races 2 and 3), carrot cv. Red Cored Chantenay (host for race 1 and nonhost for races 2 and 3), and S. bulbocastanum Dun. SB22 (nonhost for races 1 and 2 and host for race 3) (26,27,36).Resistance to M. chitwoodi and M. fallax has been identified in accessions of wild tuber-bearing Solanum species, originating mainly from Central America, such as S. bulbocastanum and S. hougasii Corr. (5,6,18). Resistance to M. chitwoodi has been transferred from a resistant genotype of S. bulbocastanum to the gene pool of the cultivated potato by somatic hybridization (1,7), and a single gene has been localized on chromosome 11 that appears to control this resistance (8). Also, various levels of resistance to M. hapla have been reported (9,15,18). Recent investigations indicated the presence of variation in host responses to different M. hapla isolates on some genotypes of S. bulbocastanum, S. hougasii, S. chacoense Bitt., S. gourlayi, S. sparsipilum, and S. spegazzinii that were selected for resistance (19).In general, the efficacy of resistance depends largely on genetic variation in the virulence of the pathogen and factors involved in the durability of resistance. Often the presence of resistance is concluded from experiments with one or a few isolates. The current study focused on the variation in virulence within M. chitwoodi, M. fallax, and M. hapla by testing s...
