Abstract

The purpose of the study was to identify the inheritance traits of economic and biological characteristics and properties in the hybrid progeny of primocane raspberry. The objects of study were 16 parental forms and progeny of 15 hybrid combinations of crosses with a total number of 1008 seedlings. It is established that in breeding of raspberry with a predominant fruiting on annual shoots, there are certain difficulties in obtaining forms with a high degree of remontancy, early, friendly crop ripening, multiple fruits and increased berry strength, as evidenced by the depression in the inheritance of these traits. Despite this, promising combinations of crosses were identified: Podarok Kashinu x Penguin, 44–154–2 x Poklon Kazakovu, 13–118–1 x 1–16–11, Podarok Kashinu x 1–16–11, 13–118–1 x Podarok Kashinu, Atlant x Bryanskoe Divo with the highest yield of transgressive seedlings. In the hybrid progeny, selections of 6–119–1, 3–170–1, 8–189–1, 11–165–10, 10–165–11, 9–163–2, 5–83–10 and others were revealed, combining the degree of remontancy, early fruiting with the components of productivity and fruit quality at a high level.

Highlights

Among berry plants, raspberry have long been popular and in demand among the population due to their unique nutritional and medical properties
The period of the most active development of raspberry breeding occurred in the second half of the last century, when there were several dozen large breeding programs of the genus Rubus in the USSR, European countries, the USA and Canada
Scientific breeding of primocane raspberry lasts less than a century

Summary

Introduction

Raspberry have long been popular and in demand among the population due to their unique nutritional and medical properties. Scientific breeding of primocane raspberry lasts less than a century The interest in this group of varieties on the part of producers is caused by low labor intensity of cultivation, possibility of mechanization of most processes for plantings management, an increase in the period of receipt of fresh berries by 2-3 months. Varieties with predominant fruiting on annual shoots are suitable for growing in open ground, tunnels and greenhouses [6, 7, 8] Due to their use, the area of successful raspberry cultivation has significantly expanded [9]. In recent years, there has been an increase in the area occupied by primocane varieties, and the share of their research in breeding programs, reaching in some cases 60-70% [2, 10, 11]
