stigma ( Ciampolini et al., 1983 ) and generally binucleate pollen ( Bradley and Griggs, 1963 ), which are considered to be two signs of gametophytic self-incompatibility ( Sedgley, 1994 ). In this sense, we always obtained pure progenies from crosses

-pollination can be offset or even overcome by self-incompatibility. C. occidentalis exhibits gametophytic self-incompatibility, which allows pollen tubes to penetrate stigmas but prevents self-fertilization by inhibiting growth of tubes within the style. The

European pear, like other fruit species of the Rosaceae, is impaired in effecting self-fertilization by a gametophytic self-incompatibility (GSI) system ( Crane and Lewis, 1942 ). In the Rosaceae, GSI is inherited as a single multiallelic locus (S

existence of gametophytic self-incompatibility in flowering dogwood and low self seed set has been observed in other studies on flowering and kousa dogwood ( Gunatilleke and Gunatilleke, 1984 ; Ohta, 1971 ; Orton, 1985 ). Ascher (1976) proposed that a
