Raspberries are among the most popular berries on the market; therefore, interest in this crop is constantly growing. Raspberries are cultivated in more than 50 countries around the world, and this number is increasing. The steady expansion of raspberry cultivation and yields is due to the scientific support of the industry with new cultivation technologies and varieties. The present study was aimed at revealing difficulties and problems in raspberry breeding and identifying current tendencies and development trends. The paper provides a brief overview of raspberry production in the world, as well as an analysis of active breeding programs in Russia and abroad. The features of the breeding tasks are considered depending on the regions of cultivation. The main problems, methods used, source materials and breeding achievements are presented. It is revealed that the overall purpose of breeding programs is to obtain productive varieties with high adaptation to abiotic and biotic stressors, suitable for various cultivation technologies and having excellent fruit quality. It was found that despite the successes achieved in raspberry breeding, at present there is still lack of varieties with high adaptation to the environment and very early or late-ripening varieties, allowing to extend the period of consumption of fresh berries, as well as lack of high-tech industrial varieties suitable for contemporary cultivation technologies, and varieties with required commodity and consumer properties. The prospects of raspberry breeding for the coming years are considered. It is shown that in order to achieve the strategic objectives in breeding, it is necessary to enrich the cultivated gene pool of raspberry with new inclusions of wild species of Rubus. This requires the cooperation and coordination of all breeding programs for the expansion and exchange of genetic resources. In order to accelerate the breeding process, it is necessary to actively use a large set of biotechnological methods tested and well-proven on berry crops. Wider use of molecular-genetic methods is essential to significantly increase the speed and accuracy of breeding.

The majority of raspberry breeding programs focus on the creation of varieties with firm and transportable fruits that can be stored for a long time without losing their quality. Our research aimed to establish the possibility of creating remontant raspberry forms with the fruit firmness exceeding that of the best modern varieties in order to identify promising parental pairs. The physical and mechanical properties of raspberry fruits harvested in 2020 were studied. The research material included 19 remontant raspberry varieties, eight selected forms and 10 combinations of crosses with the total seedling number of 627 pcs. The original parental forms and hybrid offspring were evaluated in terms of berry crushing force and detachment from the peduncle using conventional horticultural methods. During the study period, no genotypes with very soft berries were identified among the studied varieties. Only two varieties (Oranjevoye Chudo and Elegantnaya) produced soft fruits (up to 5.0 N) unsuitable for transportation. More than 65 % of the samples exhibited a medium level of firmness, thus allowing the high quality of fruits to be preserved during manual harvesting and transportation over limited distances. The Sugana, Salut, and Atlant varieties, as well as 3-59-30, 2-53-1, 44-154-2, 1-60-1, and 9-113-1 selected forms produced firm berries withstanding a crushing force of 7.2–8.3 N. In the hybrid progeny of raspberry remontant type, large variations in fruit firmness were observed, depending on the combination of crosses. The calculation of dominance degree (D = -19-0) confirmed the difficulty in transmitting the trait of high fruit firmness to progeny. Among the studied hybrid families, the yield of transgressive seedlings ranged from 1.7 to 15.6 %. Only in the 9-113-1×Salut combination, no hybrids exceeding the best parental form in terms of fruit firmness were identified. Promising combinations of crosses in breeding for obtaining remontant raspberry varieties with increased fruit firmness include the following: 9-163-1×44-154-2, Podarok Kashinu×Atlant, 9-113-1×Podarok Kashinu, 9-155-1×Atlant, as well as populations from free pollination of Zolotaya Osen, Pokusa, and the 7-42-3 selected form. In the offspring of these parental forms, the 21-166-11, 21-166-10, 8-163-10, 1-188-2, 8-163-11, 15-132-1, 6-124-21, 2-159-10, and 1-135-31 selected forms withstanding a crushing force of 8.5–10.4 N were identified.
