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. |
