Russia breeds hybrid plants from potato and tomato somatic cells, respectively

Both potato and tomato belong to the family Solanaceae. Although the tubers and fruits of some wild species are not edible, their plants have strong resistance to diseases and insect pests, salt and alkali, and cold resistance. Therefore, Russian experts, in cooperation with German and Finnish experts, used wild potato and tomato to cross potato and tomato crops, respectively, to develop hybrid plants with strong survivability. According to the latest issue of Scientific Information magazine in Russia, experts from the Institute of Plant Cultivation of the Russian Academy of Agricultural Sciences and German and Finnish researchers have eliminated the cell wall of the somatic cells of wild potato and potato plants in cooperation with the two somatic cells. They are fused together, cultivated into hybrid tissue, and plants are grown on this basis. Afterwards, the newly cultivated hybrid plants were hybridized several times with the potato crop in the same way, and finally a genetically stable potato hybrid was generated. Since then, researchers have used a similar approach to breed genetically stable tomato hybrids. The results of the analysis show that the hybrid plants thus obtained contain both the genes of the crops and their wild varieties and their plants are resistant to the infestation of some viral diseases, Phytophthora and aphids. At present, researchers are continuing to cultivate the above hybrid plants in order to cultivate them into new crops. Experts also disclosed that German experts tried to grow potatoes and tomato crops simultaneously by crossbreeding in the 1980s, but they did not succeed. Is there such a point in this effort? Future hybridization studies will hopefully give answers.
