Synthesized Assessment
According to the correlation analysis results, each fatty acid component in the seed oil of A. truncatum has a complex correlation, and it is difficult to use a particular indicator to determine the value of the population between the high and low or not, so the composite scores of each indicator between the 70 A. truncatum were calculated using the method of principal component analysis and the method of the affiliation function. There were 70 experimental materials in this experiment, and the samples with the top 10 scores were screened from high to low according to the size of the comprehensive evaluation value, and the evaluation results obtained are shown in Tables 8 and 9. According to Table 8, it can be seen that the two analytical methods resulted in the 10 highest comprehensive evaluation values were basically the same except for individual samples, and the 10 germplasm with the highest comprehensive evaluation values were STA-7, STA-3, SZB-4, and SJA-14, respectively, STA-4, STA-5, SJA-9, SZB-6, SZB-7 and SJN-2; as can be seen from Table 9, after the comprehensive evaluation of the nine populations in the two analytical methods, the resulting rankings in addition to the SJA and AWH slightly different, the rest of the population rankings do not differ, the preliminary assumption is that the habitat conditions are different resulting from the same time do not rule out the possibility of individual variation and thus affecting the scoring results. However, in general, the evaluation results were still reliable and accurate, with STA having the highest overall evaluation value among the nineA. truncatum populations, followed by SZB and SJN; the rankings of individual samples were similar to those of the populations, which further proved the accuracy of the overall evaluation. The results of this experiment provide a scientific and theoretical basis for the breeding work of screening high oil A. truncatum germplasm and genetic improvement.
