Research Methods. - Field - conducting field experiments; measurement - weight - determination of biometric parameters of plants; Laboratory - determination of the chemical composition of fruits; mathematical and statistical - evaluation of the reliability of the results of research. Developed and patented (patent №102578 from 10.11.2015) laboratory method zharo- comprehensive assessment of drought and watermelon breeding material, thereby reducing the time and seeds for their conduct and conduct a comprehensive selection of resistant genotypes at the initial stage of ontogeny. The results of the studies found correlations: between the phase of "fruit-ripening" and the length of the growing season (r = 0,57); watermelon between heat resistance and number of stomata on the underside of the leaf (r = 0,69); between the temperature of the upper and lower sides of the leaf and drought, which are respectively r = (- 0,59) and r = (- 0,52). As a result of three years of competitive sortoispytanija was the most productive new variety watermelon Mriay, which significantly exceeded standards in yield of 8.7 t / ha. Transmitted to the State sort testing three new varieties of watermelon table: Avangard(№ application 15146004) Vohnedar (№ application 15146003), Svitlaychock (№ application 15146005). Getting and transferred line with increased zharo- and cold resistance in NTSHRRU: LZZH-252-2 (№ nat. catalogy UL3900549), LPZH-252-1 (№ nat. catalogy UL3900548), LPH-252-16 (№ nat. catalogy UL3900550 ). Developed guidelines on breeding lines resistant watermelon. Product Description popup.authors Воєводін Юрій Ігорович Холодняк Олег Георгійович popup.nrat_date 2020-04-02 Close
