Study of new F1 pickling cucumber hybrids, yield and yield components.

The aim of this study was to evaluate the yield and its components of new pickling cucumber hybrids. Three F1 crosses (5551 x T/19, 5551 x P/176 and 2963 x T/19) were developed on the base of two gynoecious mother lines resistant to powdery mildew and downy mildew crossed with two monoecious lines resistant to powdery mildew. The new hybrids could be of great importance for the canning industry. They exceeded the control cultivar by relatively higher 3-6 cm and 6-9 cm (fruit size) yield percentage and formed less oversized fruits. The 5551 x T/19 hybrid produced the highest marketable yield. The differences in marketable and total yield between 5551 x T/19 and 2963 x T/19 crosses and cv. Tony F1 control were not significant. That was due to the fact that the high yield cv. Tony F1 control was used for evaluation.
