ANALYSIS OF INCROSSED PROGENIES OF EGGPLANT OF INTERSPECIFIC ORIGIN ACCORDING TO THE COMPLEX OF ECONOMICLY VALUABLE TRAITS
Abstract. The aim – to improve the gene pool of the cultured form of eggplant (Solanum melongena L.) due to interspecific hybridization with the species Solanum aethiopicum L., analysis of lines of interspecific origin based on a complex of quantitative economic and valuable traits. Methods: general scientific, measuring, weighing and weighting, variational statistics. Results. According to the results of the analysis of the investigated quantitative traits of eggplant, the peculiarities of their manifestation in experimental selections were established depending on the level of backcross crossings with the standard variety Almaz. In particular, a steady trend was noted in increasing the level of manifestation of such traits as "Fruit shape index" (Xmed = 1.2...1.8), "Average fruit weight" (Xmed = 173.8...291.7 g), "Productivity of one plant" (Xmed = 702.3...1111.7 g/plant). At the same time, in all experimental selections, the phenological phase of plant development, which determines the duration of the period from the appearance of mass seedlings to the technical ripeness of fruits, was shorter than in the standard varieties (102–105 days against 114–115 days in the standard varieties). Conclusions. In conclusion, the selection [((F5 (Pavlotas-20 / s. Almaz (original 403 g)) / s. Almaz) / s. Almaz] was distinguished by the best indicators both in terms of the phenological phase of plant development and in terms of quantitative indicators that determine yield structure. This selection was transferred to the genetic bank of vegetable plants as a promising line of eggplant of interspecies origin for breeding research with the following economic and valuable characteristics: early ripening, with a period from the appearance of mass seedlings to the onset of technical ripeness of fruits of 100–105 days; productivity of one plant at the level of 1100–1400 g/plant, which is higher than the Almaz standard variety by 28–56%; fruit length 12–14 cm, diameter 6–7 cm, weight 290–340 g. The shape of the fruit is cylindrical, light purple in color, pulp is dense without bitterness.
