| Abstract: |
| This paper analyses 10 puantitative traits of 20 cucumber hybrid combinations. Three principal branch quantitative traits were determined in accordance with the principal component analysis. The integration and interindtpendance of the principal branch quantitative traits were used to carry out the directional and comprehensive selection. Based on the magnitude of the values of principal branch components of experimental materials, the early-mature hybrid combinations ofcucumbers with the comprehensive fine traits were selected. |
