Evaluation of the adaptive potential of Chelyabinsk honeysuckle varieties in the conditions of the Southern Urals and Krasnoyarsk Territory

The aim of the research is to select adaptive varieties of honeysuckle characterized by high productivity, ecological plasticity and stability in the conditions of the forest-steppe zone of the Southern Urals and Krasnoyarsk Krai. The variety study of honeysuckle was carried out at two state variety testing sites: Shushensky GSU (forest-steppe zone of Krasnoyarsk Krai) and Chelyabinsk GSU (forest-steppe of the Southern Urals) in 2018–2021 according to the methodology of E. N. Sedov and T. P. Ogoltsova. The soil of the experimental sites is leached medium loamy chernozem. Honeysuckle was planted in 2015 according to the 3.0×1.5 m scheme. The experiment was repeated three times, the placement of plots was systematic. Sixteen honeysuckle varieties were studied (8 varieties bred by the South Ural Research Institute of Horticulture and Potato Growing (SURIHP) and 8 varieties of the Bakcharsky Northern Horticulture Support Point). The methods of S. A. Eberhart and W. A. Rassel, A. A. Rosielle and J. Hamblin, V. V. Khangil’din, L. A. Zhivotkov, and V. A. Zykin were used to analyze the adaptability indices. The soil and climatic conditions of the forest-steppe zone of the Southern Urals were more favorable for growing honeysuckle, where the average yield of the studied set of varieties (6.57 t/ha) was 3.28 times higher than in the conditions of the Krasnoyarsk Territory (2.00 t/ha). Ranking of genotypes by the sum of ranks allowed us to identify four honeysuckle varieties suitable for cultivation both in Krasnoyarsk Krai and in the Chelyabinsk Region: Chulymskaya (yield – 4.19 and 8.80 t/ha, sum of ranks – 44 and 62, respectively), Amazonka (3.37 and 6.59 t/ha; 50 and 66), Zhelannaya (2.27 and 7.21 t/ha; 53 and 61), Silginka (1.93 and 8.32 t/ha ; 62 and 52). Three varieties are highly adaptable to the forest-steppe conditions of Krasnoyarsk Krai: Bakcharsky Velikan (yield – 3.95 t/ha, sum of ranks – 46), Gorlinka (2.21 t/ha; 58) and Zarechnaya (1.75 t/ha; 58). Five varieties of honeysuckle are adapted to the conditions of the forest-steppe zone of the Southern Urals: Bakcharskaya Yubileinaya (yield – 7.98 t/ha , sum of ranks – 46), Gordost Bakchara (7.01 t/ha; 51), Narymskaya (6.78 t/ha; 58), Vasilek (6.85 t/ha; 66) and Yugana (7.06 t/ha; 69).
