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.
