| Abstract | In order to obtain a significant level of yield of table carrots in the Right-Bank Forest-Steppe of Ukraine, it is necessary to select varieties and hybrids in accordance with the soil and climatic conditions of cultivation. The comparative estimation of productivity of hybrids of carrots of table foreign selection in the specified conditions is carried out. The results of phenological observations of plant development, their biometric indicators depending on the genetic features are presented. The indicator of the total yield of table carrots according to the experiment was in the range of 65.6–80.7 t/ha. Saturno F1 had higher and this exceeds the control of Abaco F1 by 15.1 t/ha. In the structure of the yield of this hybrid marketable products are 96.0 % or 77.1 t/ha, which is more than the control of 5 % or 17.1 t/ha. In Saturno F1 non-marketable products 3.6 t/ha, which is 2.0 t/ha less than the control, and the yield of standard products 75.3 t/ha, which is a larger indicator of the experiment and exceeds the control by 17.3 t/ha. Non-standard products amounted to 1.8 t/ha. The productivity of table carrots is significantly influenced by the weight of the root, which, in turn, is affected by its length and diameter. On average, according to the years of research, their weight was at the level of 190–240 g. The roots in Abaco F1, which was the control, were smaller in weight. Larger roots formed in Saturno F1. Hybrids Baltimore F1, Bolivar F1 and Gerada F1 formed roots of 208 g, 218 g and 233 g, respectively. The diameter of the roots of the studied carrot hybrids was 4.6–5.2 cm. They were smaller in Saturno F1 and larger in Baltimore F1. The average values of root diameter for the years of study in Abaco F1 (control) are 5.1 cm; Bolivar F1 4.7 cm, and Gerada F1 5.0 cm, which is less control by 0.4 and 0.1 cm, respectively. An important varietal feature of table carrots is the length of the root. In Abaco F1 it was 18.5 cm. This is the lowest value in the experiment. In Baltimore F1 and Bolivar F1 the roots were formed of almost the same length 19.0 and 19.3 cm, respectively, which is more control by 0.5 and 0.8 cm. In Gerada F1, the roots were 23.2 cm, which is more control by 4,7 cm. Roots of Saturno F1 were longer compared to other variants of the experiment 24.5 cm, which is more control by 6 cm. The suitability of the studied hybrids of table carrots for foreign selection for growing in the conditions of the Right-Bank Forest-Steppe of Ukraine has been established. | ||
