More Information
Summary:The invention discloses a cunninghamia lanceolata seed orchard parent selection method based on multi-factor evaluation, and belongs to the technical field of genetic breeding. According to the selection method, a multi-factor analysis method is utilized, and a clone is grafted on the basis of a fourth-generation cunninghamia lanceolata selection group to construct seed orchard parents. A cunninghamia lanceolata group is used as a test material, a factor analysis model is constructed based on clone target traits, a score function is obtained according to a factor score matrix, weighted averaging is completed according to different proportions of the equation contribution rate in the total variance contribution rate, a comprehensive score equation F is obtained and substituted into a selected group, each clone is comprehensively evaluated, and a cunninghamia lanceolata group is obtained. The florescence of the garden building parents is consistent, and a foundation is provided for the creation of subsequent ne
