Abstract

Eighteen lines of tomato of different ages and origins which were obtained by intraspecific and interspecific hybridization as well as the variety Juliana as a control were tested at the temperature 10оC for cold resistance estimation. Nine most perspective lines were chosen from the results of tests conducted. The direct correlation between the cold resistance of seedless and mitotic activity of meristem was shown.
