Abstract

The purpose of the research is to select from the hazelnut gene pool collected at the L.P. Symyrenko Research Station of Pomology inland cultivars and hybrids and those bred abroad high adapted to the soil and climatic conditions of the Lisosteppe of Ukraine. Hazelnut varieties and forms were quite resistant to aphids (0.1-1 point) and leafhopper (0.2-1.5 p.) the damage by which did not affect the bushes general state and yield. The varieties Koronchatyi, Gordiienko, Fakel, Trapezund, Yantarnyi, Catalonskyi, Olympiiskyi, Davidovskyi, Kuliovyi, Halle and Raketnyi were the most resistant to the nut weevil. The highest yields were varieties and forms of hazelnuts: Grandioznyi, Wunder von Bolviller, P3M33, P4M32 (2.5 t/ha), Yantarnyi, Halle, Bomba (2.6 t/ha), Raketnyi, Lozivskyi urozhainyi, Kuliovyi, Olympiiskyi (2.7 t/ha), Trapezund, Catalonskyi (2.8 t/ha). The average nut is, g: Lozivskyi urozhainyi – 2.38, P4M32 – 2.55, Yantarnyi – 2.58, Trapezund – 2.72, Halle – 2.94, Wunder von Bolviller – 3.05, Catalonskyi – 3.13. Varieties and gybrids, which have high yield are P7M9 – 48.7 %, P4M32 – 48.8 %, Koronchatyi, Lombard red – 49 %, Catalonskyi – 49.1 %, Zhovtnevyi – 49.3 %, Yantarnyi – 49.5 %, Trapezund, Gianja – 50 %, Kudryavchik – 50.8 %, Fakel – 51.1 %. The investigations results allow to recommend to the farms of different forms of ownership to create of high productive plantations of a hazelnut in the conditions of the Right-bank Lisosteppe of Ukraine with the use of such cultivars and forms: Wunder von Bolviller, Halle, P3M33, P4M32. The studied varieties and forms are adapted well to the soil and climatic conditions, have high yield and fruit quality and are resistant to major pests and diseases.
