Semenenko L. Sourse material for breeding tomato on improvements in the quality of the fruit

Object: patterns of manifestations of quantitative traits in the wild, semicultural forms of tomato and lines created on their basis. Objective: expanding the use of wild, semicultural wild forms and finely fruitful samples of tomato breeding work, study of characteristics of variability of biochemical parameters of fruit and economic valuable characteristics in samples of different origin and nature of their manifestation in hybrid generations. Novelty: solving important scientific task to establish breeding value output material by identifying features of formation of morphological, biochemical, productive characteristics and allocation of sources to the selection of tomato. Results: The regularities of display signs of productivity and quality of fruit are established. Samples in terms of response to changing growing conditions are classified. 3 types of display of standards reactions to the environment are allocated. Close (0,7 - 0,91) relationships between characteristics are distinguished. Valuable sources are allocated by: productivity (7,1 kg / tall.), the number of bunches per plant (12-21 pcs.), fruit weight (106,2-108,4 g), dry matter content (8,21-8 51%), ascorbic acid (40,62-41,47 mg / 100 g), total sugar (5,66%), titrated acids (0,76%). 5 lines of tomato with high content of biologically valuable components in fruits, resistance to disease (7-9 B), heat resistance (5-9 B) and drought (5-7 B) are created. A variety of tomato Hudognik (50 -54 t / ha) and F1 hybrid Sandra (100 -103 t / ha) are created. №2 and №3 preparations with effective action on seed productivity (respectively 79.3 -102.6; 58,0-176,7%), weight of 1000 seeds (5,9-11,2; 0,5-0 9%), vigor (5,8-42,6; 5,0-24,3%) and seed germination of tomato (9,4-43,0; 0,5-26,2%) are fit.
