Researchers used diallel analyses to study the performance of different cucumber inbred lines and their offspring in low temperature conditions. They crossed five inbred lines to create F1 progenies and evaluated their characteristics related to growth, flowering, and yield. The study found significant differences among the parents and crosses for all traits studied. The best performance was observed in certain parental lines and their combining abilities, indicating potential for creating high-yielding hybrid combinations in cucumbers under low temperature conditions.
