Evaluation of technical adequacy of sugar beets for sugar production

The article is devoted to the results of studying promising hybrid lines selected from introduced (CIMMYT) hybrid combinations under irrigation conditions. In particular, hybrid lines in the control nursery and in competitive variety testing were assessed for resistance to leaf diseases, quantitative and qualitative characteristics and properties, compared to the standard. The yield of the introduced fifth generation bread wheat hybrid lines (F5) in the 2012-2013 years of study in the control nursery I varied widely from 59,9 to 89,8 c/ha, the height of the plant along the lines was 88,9-119,8 cm, the number of grains in the ear is 39,9-61,5 pcs, the mass of grains from the ear is 2,04-2,77 gr., the mass of 1000 grains is 36,4-55,0 gr., the content of gluten is 26,4-34,0%, IDK 24,0-118,0 instrument index, sedimentation 27,0-54,0 ml, protein content 10,5-14,2%, and vegetation period, respectively, in the interval 188-205 days. In 20132014, testing of hybrid lines in the control nursery II, yields were reduced to 30,0-67,0 c/ha, plant height 83,4-113,8 cm, etc., although in some lines number and mass of grains from the ear (respectively 78,5 pieces and 3,46 gr.), gluten content (39,2%) showed positive shifts. The prospective lines, selected according to positive signs, in 2014-2015, were studied in competitive variety testing. Yields of perspective lines studied in competitive variety testing varied within the range of 45,0-62,0 c/ha. In comparison with the standard (55,0 c/ha), compared with the high yield (62,0 and 56,5 c/ha), the lines were respectively: Starshina/Sonmez /2 and Starshina/Sonmez /3; with the number and mass of grain from the ear of T154/Kristadora /1 - 66,6 pcs.; 2,18 gr., T154/Kristadora/2 - 53,3 pieces; 1,7 gr., Starshina/ Sonmez/3 - 2,04 gr.; with a mass of 1000 grains Katia1/ Kroshka/3 - 46,0 gr., Gondvana/Demir/1 - 52,0 gr., Sonmez/ Pehlivan/1 and Starshina/Sonmez/3 - 44,8 gr., with the content index gluten Gondvana/Demir/1 - 34,0%, Sonmez/Pehlivan/1 - 37,8%; with the content of protein in grain (13,5-14,5%), T154/Kristadora/1, T154/Kristadora/2, Sonmez/Pehlivan/1, Starshina/Sonmez /2, whose recognition of this indicator in the standard (12,0% ) exceeded the last by 1,5-2,5 %. Hybrid lines with high indicators have been included in breeding program for further evaluation.
