Abstract

In breeding programs, it is important to accurately identify crop phenotypes. The purpose of this study was to determine the correlation between marker CsFemale-1 and sex phenotype of different cucumber lines. PCR with CsFemale-1 marker was applied for 120 samples from 12 pure cucumber lines (5 gynoecious and 7 monocecious lines, ten plants for each). In 50 samples of 5 gynoecious lines, PCR results showed that the correlation between marker CsFemale-1 and female phenotype was 100%. However, it was found that in 70 samples of 7 monoecious lines, the correlation between marker CsFemale-1 and monoecious lines was 42%. These data suggest that CsFemale-1 precisely identify gynoecious cucumber. However, in order to be utilized for breeding, CsFemale-1 should be combined with other markers specific for monoecious lines.
