Abstract

The use of the blue honeysuckle Lonicera caerulea subsp. altaica (Caprifoliaceae) for breeding resulted in the novel forms exceeding the parent ones in early maturity, fruit mass, biologically active compounds content and the crown shape allowing the mechanized harvesting.

Summary

Introduction

Subsection Caerulaea Rehd., or blue honeysuckles (Lonicera genus of the Caprifoliaceae Juss. family) according to the M.N. Blue honeysuckle is spread in the taiga zone of Eurasia and North America. On most of their area their berries have bitter taste and are not edible. Venulosa became the source for breeding the first cultivars of blue honeysuckle. Altaica seemed to have better prospects in the intensive breeding programs, as the species combines a number of economically valuable traits, such as high productivity, early maturity, drought resistance, firm attachment of compound fruits and high bioflavonoid content. The dominance of bitter-tasting fruits in the offspring made it difficult to use the L
