Breeding and biochemical characteristics of forms of allium created on the basis of interspecific hybridization

One of the most important crops among all types of Alliums is onion, the value of which is determined by the nutritional and medicinal properties. It is used not only as a seasoning for food, but also as a source of a number of biologically active substances. The biochemical composition of the bulbs and its green leaves in different periods of growth and development varies, depending on the variety, environmental conditions and agrotechnical methods of cultivation. Creation on the basis of interspecies hybridization of fundamentally new forms of Allium plants with a unique combination of genetic material allows to expand the possibility of selection of valuable genotypes in practical terms. The study was performed on plants of the inbred progenies I45 from BC1-2 bulbous forms of interspecific hybrids of Allium crossing combinations F5(A. cepa x A. vavilovli), F5(A. cepa x A. fistulosum). The biometric assessment was carried out after harvesting and drying the bulbs according to the "test Procedure for distinctiveness, uniformity and stability“ according to the main breeding characteristics: the color of the dry cover scales of the bulb, the mass of the bulb, the shape of the bulb...
