“…S. nigrum as well as the sexual hybrids of S. nigrum-related species and potato (Eijlander and Stiekema 1994), were shown to be resistant to P. infestans, based on a strong hypersensitive reaction (Colon et al 1993). The genotypes that resulted from the backcrosses of S. nigrum (+) 2× potato fusion products with potato were analyzed for their resistance to P. infestans.…”

“…In 1982 Binding et al reported the first fusion hybrids of this combination, but crossing experiments were not mentioned. Eijlander and Stiekema (1994) succeeded in obtaining sexual hybrids from the cross S. nigrum × Désirée and S. nigrum × a diploid breeding clone. Until now successful backcrosses of these sexual hybrids have not been reported.…”

Somatic hybrids of Solanum nigrum (+) 2× potato were successfully crossed with S. nigrum and with potato. First and second backcross progeny with S. nigrum could easily be obtained. One of the BC1 genotypes was already self-fertile. Backcrosses with potato had a much lower success rate. Only pollinations with tetraploid potato resulted in seed-containing berries. Two BC1 genotypes were obtained after 4362 pollinations from which 505 ovules were cultured. The first BC1 genotype grew vigorously in vitro and in the greenhouse and flowered abundantly. The second BC1 showed many abnormalities and dropped its flowers before anthesis. The first BC1 was again crossed with tetraploid potato and in this generation also the success rate was low. Over 5000 pollinations resulted in 1750 berries from which over 3000 ovules were obtained. Twelve plants germinated from these ovules and they were not as vigorous in vitro and in vivo as the BC1 parent. Some of the BC2 genotypes were used for further backcrosses but no BC3 plants were obtained. BC1 and BC2 genotypes that resulted from the backcross program with potato were tested for resistance to Phytophthora infestans. The BC1 genotype was as resistant as the S. nigrum fusion parent, but among the eight BC2 genotypes scored six were resistant, whereas two genotypes showing lesions were susceptible.

“…These include hairy nightshade (S. physalifolium), bittersweet nightshade (S. dulcamara), and black nightshade (S. nigrum). However, studies have shown that these species are not sexually compatible with cultivated potato (Eijlander and Stiekema 1994;McPartlan and Dale 1994) and therefore the movement of biotech traits from potato into related weeds is not likely to occur. The same is true for the incompatibility between potato and other Solanaceous crops, such as tomato, eggplant, and pepper.…”

Potato is the world's most important vegetable crop, with nearly 400 million tons produced worldwide every year, lending to stability in food supply and socioeconomic impact. In general, potato is an intensively managed crop, requiring irrigation, fertilization, and frequent pesticide applications in order to obtain the highest yields possible. Important traits are easy to find in wild relatives of potato, but their introduction using traditional breeding can take 15-20 years. This is due to sexual incompatibility between some wild and cultivated species, a desire to remove undesirable wild species traits from adapted germplasm, and difficulty in identifying broadly applicable molecular markers. Fortunately, potato is amenable to propagation via tissue culture and it is relatively easy to introduce new traits using currently available biotech transformation techniques. For these reasons, potato is arguably the crop that can benefit most by modern biotechnology. The benefits of biotech potato, such as limited gene flow to conventionally grown crops and weedy relatives, the opportunity for significant productivity and nutritional quality gains, and reductions in production cost and environmental impact, have the potential to influence the marketability of newly developed varieties. In this review we will discuss current and past efforts to develop biotech potato varieties, traits that could be impacted, and the potential effects that biotech potato could have on the industry.Resumen La papa es el cultivo hortícola más importante en el mundo, con cerca de 400 millones de toneladas producidas a nivel mundial anualmente, acreditando la estabilidad en el suministro de alimentos e impacto socioeconómico. En general, la papa es un cultivo manejado intensivamente, que requiere riego, fertilización y aplicaciones frecuentes de plaguicidas para obtener los más altos rendimientos posibles. Los caracteres importantes son fáciles de encontrar en parientes silvestres de la papa, pero su introducción usando el mejoramiento tradicional puede llevar de 15 a 20 años. Esto es debido a la incompatibilidad sexual entre algunas especies silvestres y cultivadas, el deseo para eliminar características indeseables de las especies silvestres del germoplasma adaptado, y la dificultad en la identificación de marcadores moleculares aplicables ampliamente. Afortunadamente, la papa es receptiva a la propagación por cultivo de tejidos y es relativamente fácil la introducción de nuevos caracteres usando técnicas biotecnológicas de transformación actualmente disponibles. Por estas razones, la papa es probablemente el cultivo que se puede beneficiar mayormente por la biotecnología moderna. Los beneficios de la papa biotecnológica, como el flujo genético limitado a cultivos que se siembran convencionalmente y a los parientes como malezas, la oportunidad para productividad significativa y logros en calidad nutricional, y las reducciones en los costos de producción e impacto ambiental, tienen el potencial para influenciar la comercialización...

“…nigrum cannot be efficiently crossed with a cultivated potato and the transfer of its late blight resistance to potato cultivars has been severely limited by this fact. A few infertile sexual hybrids between these species have been obtained with the use of embryo rescue technique (Eijlander and Stiekema 1994). Somatic hybridization has also been used to enable an introgression of S. nigrum resistance into S. tuberosum gene pool, with very limited success (Horsman et al 1997.…”

RESISTANCE TO PHYTOPHTHORA INFESTANS IN THREE SOLANUM NIGRUM F 3 FAMILIES ABSTRACTSolanum nigrum is a self-pollinating, hexaploid weed and one of a few Solanaceae species native to Europe. It used to be described as a non-host for Phytophthora infestans. However, now it is known that, like its distant relatives: potato (Solanum tuberosum L.) and tomato (Solanum lycopersicum L.), S. nigrum can suffer from potato late blight caused by this pathogen. Both susceptible and resistant S. nigrum genotypes have been previously identified and inheritance of resistance originating from one accession has been described based on population of F 2 plants and 15 F 3 lines. The goal of this study was to evaluate resistance of three families of F 3 lines, originating from crosses between a susceptible and three different resistant S. nigrum accessions followed by two self-pollinations. Parental accessions were tested for the spectrum of late blight resistance against 48 P. infestans isolates. The three families consisted of 106, 96 and 115 F 3 lines, respectively, and from each line 20 plants were tested for resistance to P. infestans. Laboratory detached leaf assays were performed in two dates and two replications of three leaves each. Segregation of the trait within the line allowed us to distinguish hetero-and homozygous lines. In one F 3 family, the ratio of resistant homozygotes: heterozygotes: susceptible homozygotes was 1:2:1, indicating that a single gene is most likely underlying the late blight resistance in this case. In the other two, observed segregations of the trait significantly deviated from this model suggesting more complex inheritance patterns.
