Embodiment 1
[0129] This example illustrates the specific implementation of maize heterosis pattern identification based on SSR molecular markers.
[0130] Among the selected experimental objects, the control samples were the molecular marker data of 40 SSRs from 135 domestic maize inbred lines (FengGe Wang et al, Development and characterization of a core set of SSRmarkers for fingerprinting analysis of Chinese maize varieties, Maydica, 2011, 56-1693. Hereinafter referred to as paper 1), the samples to be tested are the molecular marker data of 40 SSRs of 10 domestically popularized maize hybrids with the same loci in paper 1 (Wang Fengge et al., 328 maize varieties in China ( Combination) SSR marker genetic diversity analysis, Chinese Agricultural Sciences, 2014,47 (5): 856-864. Hereinafter referred to as paper 2), the crop heterosis pattern identification method based on molecular marker technology proposed by the present invention is verified, specifically The implementation process is...
