The invention discloses a
camellia chekiangoleosa improved variety breeding method and a
camellia chekiangoleosa improved variety breeding
system based on function superposition, and the method comprises the following steps:
cloning excellent single plants through a high-stem
grafting technology, and establishing a specific
germplasm resource
library; determining three types of phenotypic data of a floral leaf character set, an oil yield character set and an
oil quality character set; the method comprises the following steps: presetting six types of application scenes such as an
edible oil production
raw material forest and a specific
natural compound production
raw material forest, and constructing a comprehensive evaluation model by adopting a hierarchical
weight distribution method: distributing first-level weights for three types of character sets, and then distributing second-level weights for characters in subsets; standardizing the character of the floral leaf by adopting a binary comparison method, and standardizing the character of the oil yield and the character of the
oil quality by adopting a centesimal
system; and screening a target improved variety according to a comparison result of the comprehensive
score of the to-be-evaluated variety and the average
score of the existing improved variety. By means of the method, superposition breeding of ornamental,
oil production and
oil quality functions is achieved, and the adaptability of improved varieties and industrial scenes is improved.
