Research objective: to determine the race-specific resistance of millet starting material against an artificial infectious background and to create high-yielding millet varieties with a short growing season (75-85 days), complex resistance to smut and melanosis in combination with other economically valuable crop traits to increase grain production and improve its food and feed qualities. Research methods: field, laboratory, statistical. Main research results: At the stage of the task 2024, as a result of studying the overall level of economic value of new millet lines in the preliminary test and analyzing their technological qualities, 14 homozygous breeding lines were identified that combine a high level of productivity in their genotype with signs of high technological qualities of grain, resistance to lodging, melanosis and smut, of which 8 promising breeding lines are candidates for new varieties. In the race-specific resistance test nursery, we identified smut pathotypes, evaluated the resistance of pearl millet genotypes to 13 pathotypes of the pathogen on an artificial infectious background, and reproduced genetically pure spore material.   Product Description popup.authors Samborska Olena V. popup.nrat_date 2025-01-24 Close
