“…This phenomenon was found in 22 of 40 studied cultivars. Our results are in accordance with previous findings that many new apricot cultivars are self-incompatible (Burgos et al 1997;Milatović, Nikolić 2007).…”

“…Thus, Egea et al (1991) reported that pollen tubes reached the ovary in 48 h, while Guerriero and Bartolini (1995) concluded that, under ideal conditions, they reach the ovary in 48 h, but most often in 72 hours. However, according to Milatović and Nikolić (2007), 72 h was insufficient for most cultivars, so they extended this period to 120 hours. VITI et al (1997) point out that in apricot it takes pollen tubes at least 96 h to reach the ovary.…”

“…The number of known self-incompatible apricot cultivars of the European group has increased rapidly over the last two decades. Thus, Szabó and Nyéki (1991) reported self-incompatibility in nine cultivars, Burgos et al (1997) in 42 cultivars, Paydas et al (2006) in 37 cultivars and hybrids, and Milatović and Nikolić (2007) in 14 cultivars.…”

Self-(in)compatibility was tested in 40 new apricot cultivars from European breeding programmes. Pollen-tube growth in pistils from laboratory pollinations was analysed using the fluorescence microscopy. Cultivars were considered self-compatible if at least one pollen tube reached the ovary in the majority of pistils. Cultivars were considered selfincompatible if the growth of pollen tubes in the style stopped along with formation of characteristic swellings. Of the examined cultivars, 18 were self-compatible and 22 were self-incompatible. Fluorescence microscopy provides a relatively rapid and reliable method to determine self-incompatibility in apricot cultivars.

“…2002; Alonso and Socias 2005,Hedhly et al. 2005, 2007, Milatović and Nikolić 2007). Thus, compatibility determination by means of pollen tube observations has not been as clear as in other Prunus spp., probably due to the fact that most of the cultivars studied are complex hybrids resulted from the hybridization of more than two diploid plum species, in which case the compatibility reaction in the style may not to be as clear as in other intra‐specific crosses .…”

S‐RNase genotyping and incompatibility group assignment by PCR and pollination experiments in Japanese plum

Most Japanese plum-type cultivars are self-incompatible and cross pollination is necessary to ensure fruit set. In this study, the S-RNase genotype and the incompatibility group of 68 Japanese plum-type cultivars were determined by PCR amplification of the S-RNase gene. The S-RNase genotype of 50 cultivars is first reported here and five new Japanese plum S-RNase alleles (So, Sp, Sq, Sr, Ss) were identified. The results obtained, together with information compiled from previous studies, allowed describing 12 new incompatibility groups (VIII-XIX). The self-incompatibility of several cultivars and the crosscompatibility among different incompatibility groups were verified by self-and cross-pollination experiments followed by observation of pollen tube growth. Five cultivars behaved as self-compatible, but two of them do not have the Se allele, which has been correlated with selfcompatibility. Thus, additional sources of self-compatibility different from Se appear to be involved in Japanese plum self-compatibility.

“…Growth of incompatible pollen tubes is arrested in the style, while one of the compatible pollen tubes reaches the ovary. The morphology of incompatible pollen tubes differs from that of compatible ones with an abnormally large deposit of callose along the incompatible pollen tubes (Halász et al 2007a, Milatovic andNikolic 2007). Fruitlets resulting from incompatible pollination are prone to dropping.…”

Fruit crops have a growing economic importance worldwide and molecular genetics might be useful in solving many problems that arise during commercial production. One of the fields that have attracted intense attention is the molecular basis of self-incompatibility that may result in low fruit set. In tree fruits of the Rosaceae family, the incompatibility reactions take place between the pistil S-ribonuclease (S-RNase) and the pollen-expressed S-haplotype specific F-box (SFB) proteins. In most cases, the loss of self-incompatibility was associated with mutations in the S-RNase or SFB genes. A total of 27 non-functional S-haplotypes have been identified and characterized, most (24) of which emerged as a consequence of natural mutations. In the Prunoideae, most haplotypes are pollen-part mutants (50 %), while 8 are stylar-part mutants (36 %), one haplotype shows both pollen-and stylar-part mutations, and molecular changes for two haplotypes still have not been clarified. In contrast, non-functional natural haplotypes in the Maloideae are all stylar-part mutants. The analysis of such mutants may shed light on underlying molecular mechanisms as was the case with the establishment of the general inhibitor model that describes interactions between pollen and pistil S-proteins. However, several other molecules were supposed to contribute to the molecular interactions, at least in Solanaceae, a family with a similar self-incompatibility system. This review also endeavours to delineate the evolutionary implications of the S-locus mutations and collect limited data on non-S-locus molecular interactions and signaling events after self-and cross-pollination of fruit tree species.
