Abstract

In general, when the traits related to cucumber breeding are examined, morphological traits such as leaf and flower characteristics, fruit; size, shape, spines, fruit flesh set, as well as yield are among the most important factors among the breeding selection criteria. The morphological and pomological characterization of 109 plants belonging to 16 F2 lines of different fruit types under soilless agriculture conditions were carried out and lines with breeding material value were identified. The average fruit weights of the lines with different fruit types were determined as mini (snack) type 53.88 g, beith alpha type 138.84 g, gherkin type 49.95 g and long european type 194.22 g. The highest fruit flesh firmness was determined as 0.98 kg/cm2 in lines with mini (snack) fruit type, while the lowest was determined as 0.59 kg/cm2 in lines with beith alpha fruit type. Warts on the fruit surface were detected on C355 and N285 lines with gherkin fruit type and C348 line with long european fruit type, while there were without warts on the fruit surfaces of other lines. Beith alpha fruit type, 8 plants of line C350 had monoecious flower structure, while the plants of other lines had gynoic flower structure. The longest internode was 13.75 cm in line N285 and the shortest internode was 8.53 cm in line C350. Differences between lines and plants with different fruit type were determined by principal component analysis. It was determined that there was a wide variation among the plants in terms of all the traits examined and the traits that can be used as breeding material for future studies in cucumber were identified.
