The objective of the research was to assess a grade of parthenocarpic fruit and fruitsetting following cross-pollination and self-pollination in pepino plants (Solanum muricatum Ait.). An experiment with six pepino clones of different origin was set up in glasshouse conditions. Experimental clones were subjected to the following treatments: self-pollination, cross-pollination, and emasculation without any control. The tested clones of pepino were self-pollinated, capable of cross pollination and facultative parthenocarpic. The differences between clones in their ability to parthenocarpic fruit formation were observed. The ripening period of pepino fruits and their weight depended on a clone.

Key words: clone, self-pollination, cross-pollination, emasculation
