Genome Size Variation in Malus Species

Table 2

1Cx-values (*Median) of Malus species demonstrating different ploidy levels. For statistical analysis, differences among the levels were tested by non-parametric tests: either by the Mann-Whitney Test (in case of 2 levels) or by the the Kruskal-Wallis Test together with Dunn's Multiple Test (in case of more than 2 levels). Species with the same letter are not significantly different at 5% level.
