Cluster analysis of morphological traits in cucumber hybrid varieties (Ukrainian Right-Bank Forest-Steppe area)

The influence of weather conditions on vegetable crops plays an important role in the cucumber production. The biggest amount of cultivated fields is situated in the areas that are under risk for agriculture. Our research aim is to study different cucumber heterozygous hybrid varieties. Their chemical composition, crop formation, growing season, stem thickness near the root collar, main stem length, leaf area, leaf number per plant are of great importance to form clusters, the samples of which could give the highest cucumber productivity under Ukraine Right-Bank Forest-Steppe conditions. The samples of 36 cucumber heterozygous hybrid varieties of Ukrainian and foreign breeding (Russian, Italian, French) have been studied at Bila Tserkva National Agrarian University Training and Production Center. The variety estimation of 36 heterozygous samples shows that they have 17 traits. It has allowed us to subdivide them into five clusters at the lowest level under Ukraine Right-Bank Forest-Steppe conditions. In the plant nursery, all cucumber varieties are presented by six the most common hybrid samples. There are three samples that have been bred in Ukraine (Suvenir F1, Lyaluk F1, Vodogray F1), 1 in Poland (Sremski F1) and 2 in The Netherlands (Masha F1, Crispina F1).
