  • FT, flowering time; SL, length until first silique; TL, total plant length; IB, main inflorescence branch number; BB, basal branch number; TB, total branch number.

  • a Among-genotype variance component from ANOVA: tests whether genetic differences exist among genotypes for specified traits (P < 0.0001).

  • b Residual variance component from ANOVA.

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

  • d Coefficient of genetic variation calculated as Embedded Image.

  • e Landsberg erecta parent.

  • f Cape Verde Islands parent.
