This invention discloses PCR primers and identification methods for distinguishing the sex of poplar trees from five major groups and the sex genotype of the white poplar group. This invention is based on the sex-determining gene in poplar trees. FERR Genes and FERR-R Specific primers were designed for each gene, and a PCR primer set for detecting the sex of poplar trees from five different groups was finally obtained through screening. PCR detection results of poplar materials with known sex using this primer set were completely consistent with the actual poplar sex phenotype, demonstrating that the PCR primer set provided by this invention can accurately identify the sex of poplar trees from the five different groups at the molecular level, making poplar sex identification more universal. Furthermore, the specific amplification provided by this invention... FERR The primer pairs for the gene can accurately identify the sex chromosome composition of poplar species. This invention has significant application prospects in the identification of male and female sexes in the five major poplar species, molecular breeding of poplars, and the control of female tree fluff.

The invention discloses a comprehensive evaluation method for drought resistance of camellia oleifera based on multi-dimensional indexes and application of the comprehensive evaluation method, and relates to the technical field of plant stress resistance breeding. Performing drought stress treatment on the tea-oil tree material to be tested; 27 indexes of the tea-oil tree material to be tested are measured; a membership function analysis method is combined with principal component analysis, 19 key indexes are selected, and membership function values and weight coefficients are calculated; calculating a drought resistance coefficient; calculating drought resistance comprehensive evaluation values, and sorting according to the comprehensive evaluation values; and selecting a drought-resistant variety and a sensitive variety according to the sequence, and carrying out transcriptome comparative analysis and screening to obtain a drought-resistant key gene. According to the method, multi-dimensional indexes are constructed, key indexes are screened from the indexes, objectivity of evaluation results can be guaranteed conveniently, the drought-resistant varieties and sensitive varieties with typicality can be rapidly screened out from drought-resistant sequencing, drought-resistant key genes can be conveniently obtained through screening, then the drought-resistant key genes are applied to subsequent camellia oleifera molecular breeding, and good application prospects are achieved.
