The effects of self-incompatibility control substance (SICS) on self-pollination, fruit set, fruit weight, and seed number of pear cultivars ‘Manpung’, ‘Wonhwang’, and ‘Niitaka’ were investigated. SICS at 1 or 2 mLㆍL?¹ was sprayed at 1 day before (BHP) or after hand pollination (AHP), BHP using reduced pollen volume (BHPR), and 1 day before (BFB), during (DFB), and 1 day after full bloom (AFB). Untreated and hand pollinated (HP) trees DFB were used as control treatments. All hand pollinations were done DFB. Simple sequence repeat (SSR) gene analysis of ‘Niitaka’ seeds was conducted to determine the effect of SICS on self-pollination. Results showed that SICS applied BHP or AHP did not induce higher fruit set than HP. Only in ‘Niitaka’, SICS at 1 mLㆍL?¹ applied BHPR induced higher fruit set than HP. All SICS at 1 or 2 mLㆍL?¹ applied BFB in ‘Manpung’, and BFB and AFB in ‘Wonhwang’ yielded higher fruit set than HP, but when applied at different blooming stages in ‘Niitaka’, no treatment induced higher fruit set than HP. SICS treated trees induced higher fruit set than untreated control, and SICS applied BHP, BFB, and DFB always performed better than that applied AHP or AFB. There was no general trend on the effects on number of seeds and fruit weight. SSR gene analysis revealed that SICS promoted self-pollination at 2 mLㆍL?¹ applied DFB and at 1 mLㆍL?¹ applied BHP.
