Contingency table based on rhAmp genotyping of SNP_36780842 and SNP_48607347 at three levels—annual vs. biennial beets, bolters and non-bolters of the biennial beets, and autumn-sown and spring-sown varieties.

The bold values represent the count of individuals obtained in each category along with a percentage calculated based on the total number of individuals test. The chi-square value provides a measure of the correlation between the categorial variables (the phenotype and the allele of the SNP in each case), and the p-value indicates if the statistical test resulted significant (p < 0.05).
