The influence of methods of obtaining planting material on the formation of productivity in blue honeysuckle plantations

Blue honeysuckle has successfully become one of the industrial berry crops of the XXI century. The area of blue honeysuckle plantations in Russia exceeds 500 hectares. More than 210 varieties of blue honeysuckle of Russian and foreign breeding were collected at the experimental sites of the SPC “Agropishcheprom”. As a result of the breeding work carried out, the Michurinskoye Divo blue honeysuckle variety, which has a set of requirements for industrial varieties, was transferred to the state variety testing. The main problem when laying commercial blue honeysuckle plantations is the lack of high-quality planting material of new varieties. Planting material of blue honeysuckle, on an industrial scale, is obtained in several ways: hardwood cuttings, soft wood cuttings and in vitro method. The work presents the results of studying the influence of planting material obtained by various methods and used when establishing plantations for the growth, development and formation of productivity of the Michurinskoe Divo blue honeysuckle variety. The positive influence of the in vitro propagation method for the qualitative indicators of the root system of the obtained seedlings, growth activity, potential productivity and yield in the production plantings of the Michurinskoe Divo blue honeysuckle variety, in comparison with seedlings obtained by other reproduction methods, was revealed
