Abstract: Wild relatives of eggplant are commonly exploited for tomato improvement, but the genetic
improvement relies on the information on the genetic basis of the inheritance of traits. In this study, two tomato
lines, one with oriental and another with occidental cytoplasm, were crossed with four testers representing
three wild species, namely, Solanum chilence, S.pimpiniphellium и Lycopersicon peruvianum var.
humifusum. The Line × Tester cross produced a total of eight interspecific hybrids. Parents and their hybrids
were evaluated for 3 biochemical, 12 morphological, and 8 Tomato Analyzer-based descriptors. A significant
amount of variation was noticed for all 23 traits studied. The higher values for the specific combining ability
(SCA) component was determined as compared to the general combining ability (GCA) component. The
testers were more significant for most traits than the cultivated varieties. Positive heterosis was determined for
the 12 characteristics and negative heterosis for the 11 attributes. Overall, S.pimpiniphellium и Lycopersicon
peruvianum var. humifusum was better for the biochemical traits’ improvement, whereas S. chilence was a
better tester for the morphological traits.

Введение Помидор (Solanum lycopersicum L., 2n = 2x = 24, семейство пасленовых)обычно фруктовый
овощ. Его происхождение и одомашнивание началось в Андском регионе Южной Америки и в
Мексике от дикого предка S.lycopersicum cerasiforme (Bai and Lindhout., 2007).
