Abstract | In order to obtain a high yield of carrots in the Right Bank Forest-Steppe of Ukraine, it is necessary to select varieties and hybrids adapted to the soil and climatic conditions of cultivation. Biometric measurements of plants were performed in the phase of bunch ripeness and technical maturity. At the time of the first measurement, the plants of the cultivars had 16–23 leaves and a height of 17.2–20.8 cm, and the hybrids had 15–22 leaves and a height of 17.5–22.2 cm. The boundaries of the cultivars had larger parameters in Francis, and in hybrids – in Les Saintes F1. In the phase of technical ripeness, varietal plants had 11–14 leaves and a height of 30.2–34.4 cm, and hybrid plants had 12–15 leaves and a height of 32.8–36.5 cm. According to these parameters, Francis plants were the best for varieties, and for hybrids – Les Saintes F1. The total yield of carrots was 67.1–80.5 t/ha, of which 60.5–76.3 t/ha were marketed. Root crops of the non-marketable fraction occupied 4.0–6.8 t/ha. Among commercial products, standard was 57.8–74.8 t/ha, and non-standard 1.5–2.7 t/ha. The Katrin variety provided us with 67.1 t/ha of root crops with a marketability of 90 %. Of them, marketable products were 60.5 t/ha, non-marketable – 6.6 t/ha, standard root crops were 60.5 t/ha, and non-standard 2.7 t/ha. The Favorite variety (control) provided 73.3 t/ha of production with a marketability of root crops of 92 %. Thus, there were 67.2 t/ha of marketable root crops, 6.1 t/ha of non-marketable root crops, 64.8 t/ha of standard production, and 2.4 t/ha of non-standard root crops. The Francis variety produced 78.4 t/ha of products with a marketability of 95 %. Commercial root crops were 74.4 t/ha, non-commercial products were 4.0 t/ha, standard products were 72.6 t/ha, and non-standard 1.8 t/ha. Les Saintes F1 produced 80.5 t/ha of roots. Marketable was 76.3 t/ha, non-marketable – 4.2 t/ha. Standard production was 74.8 t/ha, and non-standard production was 1.5 t/ha. Marketability is 95 %. Rufina F1 (control) formed 78.3 t/ha of roots. Of them, 72.3 t/ha of marketable products, 6.0 t/ha of non-marketable products. Standard production occupied 69.9 t/ha, and non-standard – 2.4 t/ha. Marketability was 92 %. Carlano F1 provided 76.5 t/ha of root crops with marketability of 91 %. Commodity production was 69.7 t/ha, and non-commodity production was 6.8 t/ha. Standard root crops occupied 67.0 t/ha, and non-standard – 2.7 t/ha. So, carrot hybrids have the ability to produce better yields than varieties. The production of hybrids has a higher marketability of root crops | ||
