Abstract
Cauliflower is a food product highly regarded for its nutritional, taste and especially dietary properties. The studies noted that it is chemical composition depends on the growing region and on the meteorological conditions of the growing season. It were studied 36 samples of cauliflower from a new set of the VIR world collection: from Russia – 4, the Netherlands – 18, Japan – 4, 2 from Sweden and India, and one by one from Germany, Denmark, Poland, Italy, Bangladesh, Canada. Chemical analysis was implemented at the VIR Institute of Biochemistry and Molecular Biology (St. Petersburg). In the Dagestan experimental station in 2009-2011 a small-size plot experiments were laid to determine chemical indicators on a wider assortment of cauliflower – Brassica cauliflower Lizg. during the summer-autumn cultivation period. Seeds were sown in the ridges on June 15 - 20, seedlings were planted in the field on July 25-30. The registration plot area is 8.4 m2. “Ariel” variety was taken as the standard. To determine the chemical composition the samples were collected during the period when the plants reached 50-75% of the plant heads availability. Agricultural techniques of cauliflower cultivation is common for the zone of cultivation of cabbage varieties. Trial establishment and field tests were carried out in accordance with the VIR methodological guidelines; statistical data processing according to B.A.Dospekhov. Varieties and hybrids of cauliflower with a chemical composition high content: protein, sum of sugars, monosaccharides, saccharose, malic acid and soluble solids content were isolated. From the studied varieties and hybrids of cauliflower were identified plants according to a complex of economically valuable traits and productivity. These are the samples Divita F1 – 3.48 kg / m2, Minamonte F1 – 3.27, Gregor – 3.21, Casper F1 – 2.94, Lukra – 2.94, Décora F1 – 2.73, Pindus – 2, 70, Frebo F1 – 2.49 (Netherlands) and Aristo – 2.88 (Sweden), Ariel – 2.13 kg / m2.
