Characteristics of perennial forms of interspecific hybrids of alliums

In breeding programs agriculture, interspecies hybridization is an important tool for creating a genetically updated source material In the breeding of varieties. The material consisted of perennial plants of interspecific hybrids of onions BC2(F3-5(A. cepa x A. fistulosum)), BC1(F1-5(A. cepa x A. vavilovii)), F5(A. cepa x A. altaicum) and their inbred offspring. As standard on biometrics and the susceptibility of plants with downy mildew used a variety of onion Odintsovets, as this grade participated in the conduct of the saturating crosses of onion and perennial species A. fistulosum L., A. altaicum Pall. Field experiments were carried out according to the standard technique in conditions of the Moscow region at the experimental base of FSBSI FSVC. Based on the results of the research highlighted in the form of combinations of the cross A. cepa x A. vavilovii and A. cepa x A. fistulosum and A. cepa x A. altaicum interest to breeding in number of leaves, length of leaves, number of seedstalks, the height of the seedstalks, high fertility and relatively high resistance to Peronospora destructor...
