Evaluation of the morphological, physiological and biochemical parameters of edible carrot (Daucus sativus Röhl.)

Abstract

In 2005–2006, at the Lithuanian Institute of Horticulture there were investigated and evaluated three cultivars of edible carrot of Lithuanian selection (‘Garduolės’, ‘Šatrija’, ‘Vaiguva’), two hybrids (‘Svalia’ F1, ‘Skalsa’ F1) and five perspective breeding numbers (1680 F1, 2031 F1, 2030 F1, 1859 F1, 2049 F1). The hybrid ‘Svalia’ accumulated the biggest amount of carotene (26.2 mg 100 g‑1), less nitrates (173.7 mg kg–1) and had a good storability (86.1%) of their root-crops during winter time. The perspective breeding number 2030 F1 was productive (total yield – 64.0 t ha–1), its root-crop shape was nice-looking (length 18.9 cm and diameter 4.1 cm) and their storability during winter time reached 88.7%.
