The purpose of research - accelerating the process and reduce the cost of new heat-resistant high-quality and potential productivity fruit vegetable lines using complex methods to assess the source and breeding material in the primary stages of organogenesis. Research Methods. - Field - conducting field experiments; measurement - weight - determination of biometric parameters of plants; Laboratory - determination of the chemical composition of the fruit, batteries content in soil; mathematical and statistical - evaluation of the reliability of the results of research; organoleptic. The results of the studies found correlations: between heat resistance and number of stomata on the underside of the leaf (r = 0,81 - 0,84), heat resistance and leaf area of ?sweet pepper (r = 0,54), in between the tomato - long period "stairs - ripening" with a length of interphase period of "flowering - maturation" (r = 0,89), in eggplant and sweet pepper long period between the "ladder - biological ripeness" of the interphase period of "flowering-biological ripeness" (r = 0.76) and (r = 0,66), respectively. Established that the established ripening varieties and hybrids should lead the selection of samples with short periods of interphase "bloom - maturing" in tomatoes, "bloom-biological maturity" - in eggplant and sweet pepper. Developed and patented method of field heat resistance evaluation vegetables by the number of stomata on the underside of the leaf and the method of assessing the quality of fresh fruits tomato. The method (patent №102645 from 10.11.2015) selection of resistant lines of vegetable crops. The selection is carried out after heating seedlings in a thermostat at 40 °C tomato and sweet pepper and eggplant 43 °C for 6 hours. Selected sprouts largest growth, which is in the range of +2 to +3 standard deviations from the mean value for a population increase. Created and submitted to the tomato NTSHRRU 3 lines, 3 lines of sweet pepper and 3 lines of eggplant with the highest capacity on the basis of the combination of heat resistance, productivity and solids content. The results of the competitive sort testing in 2015 was the best new variety of tomato Frigate, which significantly exceeded the standard for the grade Gentle yield 9.6 t/ha. Perspective sort of sweet pepper Odyssey significantly exceeded by the Scythians Zlato standard yield of 5.2 t/ha of dry soluble matter content of 0.6%. The most productive was sort of egg plant Zabava, which gave reliable affects an increase of 5.4 t/ha compared with the standard. Grades transferred to the state variety trials.
