Turkey is among the rare countries in terms of plant diversity, and thus, most plant species spread widely throughout the country. Apricot is one of these plant species. Due to the self-incompatibility seen in apricots, it is necessary to use a pollinator variety for a quality and efficient product. With this study carried out in 2021 year, the effects of different pollinators on fruit set and some fruit quality parameters of Casne Drenova, Ninfa and P. de Tyrinthe cultivars were investigated in Kayseri ecological conditions. In the study, early ripening apricot varieties were used as paternal parent. According to the results of the study, it was shown that fruit set values varied between 11.6% and 22.6%. In the pomological parameters examined in the study, in general (except for fruit firmness), differences were found in combinations using different pollinators compared to the open pollinated fruits of the maternal parent. It is foreseen that the results obtained will be guiding especially in the breeding studies to be carried out with these varieties and in the establishment of new orchards.

Background. There are three species cultivated in Russia: Cucurbita pepo, C. maxima, and C. moschata, the latter being the most thermophilic among them. Cultivars of C. moschata are grown in southern regions, where a growing season of no less than 110–130 days is required. C. moschata has no bushy cultivars suitable for cultivation. The aim of this study was to search for, identify and develop source material of C. moschata for breeding early-ripening bushy and short-vined cultivars.Materials and methods. Accessions from the VIR collection, advanced cultivars, hybrids and lines of various generations served as research material. The study was based on the guidelines for studying and maintenance of the collection and for cucurbit crop breeding.Results. Source material was identified for breeding practice: early accessions (90–98 days) possessing high productivity and fruit quality, with good taste, namely ‘Early Butternut’, ‘Butternut’, ‘Waltham Butternut’; accession k-3549, ‘Orekhovy’, and accession k-4235; and mid-early accessions (104–105 days) ‘Palov-kadu’, and ‘Aydzu Аkkikudza’. They exceeded in productivity the early-ripening reference (cv. ‘Mariya’) by 26.7–130%, and matched the reference in fruit quality. Hybrids from the crosses of vined accessions with the bushy form KL 745 were studied. Bushiness is inherited monogenetically and controlled by the recessive bu (bush) gene. Identified for breeding were early (93–95 days) bushy lines (KL) with a stem length of 0.8–1.2 m: KL 648, KL 652 and KL 656. Their productivity was within 4.2–4.5 kg per plant (higher than the reference by 40–50%). In fruit quality they were on the reference level. Early (92–98 days) short-vined lines (KPL) were identified, with a stem length of 1.3–2.0 m: KPL 168, KPL 640 and KPL 680; their productivity ranged 4.9–6.8 kg per plant, and their fruit quality was good or excellent.

Southern highbush blueberry, a hybrid of northern highbush (Vaccinium corymbosum) and southern-adapted Vaccinium species, has the potential to meet the need for an early-ripening blueberry in the southern U.S. southern highbush cultivars can ripen up to one month earlier than the earliest rabbiteye (Vaccinium ashei) cultivars currently grown in the southern U.S. However, chilling requirement and cold-hardiness are cultivar-dependent for southern highbush and cultivar testing has been necessary to determine the cultivars best adapted to specific hardiness zones. In a 4-year study at Hope, Ark. (hardiness zone 7b), several southern highbush cultivars were evaluated for productivity, fruit quality and reliability of cropping. Yields were based on 1089 plants/acre (2690 plants/ha) for southern highbush cultivars and 605 plants/acre (1494 plants/ha) for rabbiteye cultivars. `Ozarkblue' and `Legacy' showed the most adaptability at this location, yielding on average 11,013 lb/acre (12,309 kg·ha-1) and 10,328 lb/acre (11,543 kg·ha-1) respectively, compared to 4882 lb/acre (5456 kg·ha-1) for `Premier' (rabbiteye) over 4 years. `Ozarkblue' and `Legacy' also rated well for plant vigor and fruit quality. We would recommend `Ozarkblue' and `Legacy' for commercial planting in southwest Arkansas and believe these cultivars have production potential for other areas of the southern U.S. that have similar hardiness zones and soil type to southwest Arkansas.

The author has presented the results the yield and fruit quality of 21 introduced apple varieties of winter ripening in the conditions of Podillia. By the results of the five-year studying (2016-2020) of the studied varieties their estimation was carried out according to the complex of such qualities as early ripening, productivity, marketability, tast qualities and durability of fruits. The following introduced cultivars are difined to be the best: Graf Ezzo, Siabrina, Selena, Nadzieiny. The most early fruiting variety in the experiment was Siabrina (in the first year of growth in the orchard). At the age of two – ‘Angold’, ‘Ariwa’, ‘Beni Shogun Fuji’, ‘Graf Ezzo’, ‘Goldrush’, ‘Imant’, ‘Cameo’, ‘Nadzieiny’, ‘Rumiany Alpinist’, ‘Selena’, ‘Honeycrisp’ and control varieties Idared and Askolda began to bear fruit. At the latest (in the fourth year after planting in the garden) came into commercial fruiting plants varieties Pink Lady and Red Chief. The yield of five- nine-year old trees of the best varieties reaches 18,2-24,7 t/ha. The fastest growing yields at the age of two or six and fruiting annually trees varieties Siabrina, Selena, Angold, Ligol, Beni Shogun Fuji. The yield of the highest and first grade fruits in the best varieties Graf Ezzo, Siabrina, Selena, Nadzeiiny in 2016-2020 was 26-48 %. The lowest (19-24 %) this indicator was in the varieties Angold, Imant, Ligol, Fuji Kiku. Fruits of the best grades are more than the average sizes (Nadzieiny, Siabrina, Selena) and big (Graf Ezzo), average one-dimensionality, excellent, very harmonious sour-sweet taste (7,8-8,4 points), except for the Nadzeiiny grade (6,7 points). Apples of the best varieties were stored for 4-5 months. The fruits of control varieties Idared, Askolda and varieties Ariwa, Garant, Rubinola, Topaz, Fuji Kiku, Hillwell Braeburn were stored the longest (6-7 months).
