Table 2. Genotype fertilities (least squares means) from tests of allelism at the three co-localized QTL.

QTL region	sss1.2		sss2.1		pf7.2
Fertility trait	seed	HSD	seed	HSD	pollen	HSD
SL	60.83	A	60.83	A	0.9	A
NILPP	10.41	C	11.08	B	0.81	B

Contrasts between all means within a test (i.e. for each locus) were corrected for multiple testing (Tukey tests of Honest Significant Difference (HSD)); different letters indicate significantly different means within each locus.
