“…SI is one of the important traits for seedless fruit production as many Citrus plants have a high degree of parthenocarpy (Iwamasa and Oba, 1980;Vardi et al, 2000;Yamamoto and Tominaga, 2002). In Citrus, unlike Rosaceae fruit trees for which studies on the SI system or S-RNase-SLF/SFB gene system have been performed at the molecular level (Yamane and Tao, 2009), there is no or only a little information about the number of S 405 genes, S-allelic variation, S-allele frequencies, and S genotypes of cultivars (Ngo et al, 2010;Wakana et al, 1998).…”

Gametophytic self-incompatibility (SI), an important character for breeding seedless cultivars of Citrus, is known in pummelo, mandarin, and many hybrid cultivars with pummelo in their pedigrees. Only a little is known about the allelic variation in the self-incompatibility gene (S), S allele frequencies, and the genotypes of self-incompatible and semi-self-compatible cultivars. In this study, pollination of 'Banpeiyu' S 1 seedlings with 'Banpeiyu' and pollination between the S 1 seedlings were performed to determine homozygous S 1 seedlings for the S gene. Seventyeight Citrus accessions, including 55 pummelo accessions, were pollinated with each of two homozygous S 1 seedlings (S 1 S 1 and S 2 S 2 ). Pollen tube arrest in the style base of their pollinated pistils indicated that 23 accessions, including 'Banpeiyu', have an S 1 allele each and 16 accessions, including 'Banpeiyu', have an S 2 allele each. Frequency of accessions with S 1 allele was 29.9% (23 of 77 accessions examined) and S 1 allele frequency was 16.4% (23 of 140 alleles excluding S f allele). Frequency of accessions with S 2 allele was 21.3% (16 of 75 accessions examined) and S 2 allele frequency was 11.6% (16 of 138 alleles excluding S f allele). Pummelo accessions collected from Kagoshima Prefecture had S 1 alleles with two and half times higher frequency (56.3%) than that in all accessions examined. Of the 79 accessions, six accessions ('Banpeiyu', 'Iriki Buntan', 'Kaopang', Nagashima Buntan No. 6, Nagashima Buntan No. 7, and 'Soyu') were S 1 S 2 genotypes. The Citrus cultivars, whose S genotypes have been fully determined in this study, were

“…For example, Vardi et al (1988) used irradiated pollen to screen hybrids for pollen-stimulated parthenocarpy. Others have enclosed flowers, emasculated first or left intact, within bags (Vithanage, 1991;Wallace and Lee, 1999), isolated trees from pollinators (van Horn and Todd, 1954;Sykes and Possingham, 1992), used insect repellents to prevent pollinator visits (Manzoorul-Haq et al, 1978), or assumed that the development of seedless fruit indicated a parthenocarpic tendency (Vardi et al, 2000). This paper reports a series of experiments conducted to investigate whether or not Citrus trees can be screened for their parthenocarpic ability by excluding insects at flowering, in order to develop a test for evaluating variants in a breeding programme.…”

Self-incompatibility and compatibility of 65 citrus accessions were determined by pollen tube growth in the style. Lemon was self-compatible whereas the six pummelos and seven out of 11 its relatives were self-incompatible. Furthermore, among sour oranges and their relatives, two out of six accessions were, likewise, self-incompatible as were one out of five sweet orange and their relatives. Every yuzu and its relatives, except hyuga-natsu, were self-compatible. Of the mandarin and its relatives, 14 out of 28 accessions were self-incompatible, whereas calamondin, a kumquat relative, and Hedzuka daidai of diverse origin were self-compatible. Thirty-one out of 65 accessions used in this study were self-incompatible. Of the self-incompatible accessions, clementine and 'Ariake', a hybrid of navel orange and clementine, were crossincompatible. Thus, the incompatible genotypes of those two accessions were considered to be identical.
