A CAPS marker developed on pseudo-chromosome 11 co-segregates with sex in F1 progeny derived from a cross between female (P3) and male (P4) parents. a Agarose gel electrophoresis of the CAPS marker, sp1, for the parents and F1 progeny segregating for male and female phenotypes. This marker segregates for a non-cleaved band (854 bp) indicated as (A) and cleaved bands (425 bp + 428 bp) indicated as (B). b Frequency of the sp1 genotypes (A/B or A/A) among the F1 progeny segregating for male (50 plants) and female (50 plants). There is a statistically significant association between A/B sp1 genotype and male and between A/A sp1 genotype and female (Fisher’s exact test: P = 1.913e-14)
