Figure 5.
Parallel boxplots of 78 families of putative tropical haploid inducer in three cycles of selection for haploid induction ability. (a) Haploid induction rate (%); (b) Haploid seed number per ear; (c) Inducer seed rate (%); (d) Inducer seed number per ear (e) R1-nj intensity of endosperm; (f) R1-nj intensity of embryo; and (g) R1-nj area of endosperm. b realized genetic gain per cycle. R2 coefficient of determination. %Δ is percentage increase due to selection. *, ** b values are significantly different from zero at ≥2SE and ≥SE, respectively. ns b value is not significantly different from zero at ≥SE.
