Abstract:
Taking seedlings of hybrid F1 generation of ‘Cenruan 24’ and ‘Xianghua Oil Tea 109’ as test materials，statistical methods such as frequency analysis，correlation analysis，and cluster analysis were used to study on the leaf phenotypic diversity of 145 individual plants in the F1 generation,in order to lay the foundation for early identification and germplasm screening of hybrid offspring.The results showed that the phenotypic traits of 9 leaves of F1 hybrid generation had different degrees of variation，and the coefficient of variation ranged from 8.77% to 22.80%.In F1 generation，the advantage rates of the nine leaf phenotypy traits ranged from -18.83% to 77.14%，and heterobletiosis rates ranged from -33.19% to 62.75%.The genetic transmission of leaf length，leaf width，leaf circumference，leaf area，chlorophyll reference value and blue component value exceeded 100%.Among the 36 pairs of correlation analysis，there were 10 pairs of extremely significant positive correlation，5 pairs of extremely significant negative correlation，1 pair of significant positive correlation and 1 pair of significant negative correlation.The 145 single plants of F1 generation were divided into 4 groups by systematic clustering，and the clustering results fully reflected the characteristics of each group.
