Creation stages and ways of studying the efficiency of sugar beet hybrids of various genetic bases

Verkhnyachska research and selection station (VRSS) is widely known for its aborigineous, combining-capable multigerm pollinators’ (MP), which made the base of new hybrids sugar beet such as Kozak, Dzhura, Heroy etc. Modern are capable to realize genotype caused potential high efciency in changeable conditions. MP1, MP2 MP 3 have been constantly used program "Betaintercross" pollinators parental components hybrids. The paper presents results ecological test (ET) created tested under this program. estimation their simultaneously ET all zones production Ukraine presented paper. parameters allowed characterize hybrids, establish direction (high-yielding, sugary), provide comprehensive fast assessment adaptation various agroclimatic conditions cultivation can further probable certain hybrid with maximal following requirements a zone choice optimum formation. study best experimental 2019–2021 testing using verkhnyatska selection. perspective obtained hybridizations origin MPs Male sterile (MS) lines gene plasma.
