Characterization of promising potato genotypes bred in FSC of Agricultural Biotechnology of the Far East named after A.K. Chaika under the conditions of the monsoon climate

Abstract

After many years of research, we identified two promising hybrids Pri-14-4-2 Ocharovanie × Gala and Pri-14-36-3 Rucheek × Gala with a yield of 35.3-48.9 t/ha, the mass of a marketable tuber130-140 g and the percentage of marketable tubers 93.4-94.5%. Tubers of the identified genotypes contained 23.0 % and 21.3 % of a dry matter, 15.7 % and 14.6 % of starch, 21.5 and 18.9 mg of vitamin C per 100 g, respectively. The samples had field resistance to the main plant pathogens of the Russian Far East. The State test showed that the identified genotypes were resistant to the potato wart disease (S. endobioticum, the pathotype of Dahlem) and the potato cyst nematode (Globoderarostochiensis, the Rol pathotype).
