  • a Among-ecotype variance component from ANOVA; tests whether genetic differences exist among ecotypes for specified traits: ****P ≤ 0.0001.

  • b Residual variance component from ANOVA.

  • c Measure of total phenotypic variance attributable to genetic differences among ecotypes (broad sense heritability) calculated as VG/(VG + VE).

  • d Coefficient of genetic variation calculated as Embedded Image .
