“…Chinese and Central Asian cultivars are predominantly SI, 60% of the Turkish and nearly 20% of the traditional Hungarian cultivars are SI, while most Western European cultivars are SC (Mehlenbacher et al ., 1991; Paydas et al ., 2006). Accordingly, genetic diversity decreases from east to south‐west (Hagen et al ., 2002), a consequence of selection for high and reliable yield.…”

Origin and dissemination of the pollen‐part mutated S_C haplotype which confers self‐compatibility in apricot (Prunus armeniaca)

2007

Summary• In China, its centre of origin, apricot ( Prunus armeniaca ) is self-incompatible. However, most European cultivars are self-compatible. In most cases, selfcompatibility is a result of a loss-of-function mutation within the pollen gene ( SFB ) in the S C haplotype. Controlled pollinations performed in this work revealed that the cross 'Ceglédi óriás' ( S 8 S 9 ) × 'Ceglédi arany' ( S C S 9 ) set well, as expected, but the reciprocal cross did not.• Apricot S 8 , S 9 and S C haplotypes were analysed using a multilevel approach including fruit set evaluation, pollen tube growth analysis, RNase activity assays, polymerase chain reaction (PCR) analysis and DNA sequencing of the S-RNase and SFB alleles.• SFB 8 was revealed to be the first known progenitor allele of a naturally occurring self-compatibility allele in Prunus , and consequently S C = . The first intron of S C -RNase is a phase one intron, indicating its more recent evolutionary origin compared with the second intron. Sequence analysis of different cultivars revealed that more single nucleotide polymorphisms accumulated in S C -RNase than in SFB C . New methods were designed to allow high-throughput analysis of S genotypes of apricot cultivars and selections.• S-RNase sequence data from various sources helped to elucidate the putative origin and dissemination of self-compatibility in apricot conferred by the S C haplotype.

“…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.…”

Testing of self-(in)compatibility in apricot cultivars from European breeding programmes

2013

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.

“…In this study, the highest germination rate was obtained in Flopria variety with 59.63%, while the lowest germination rate was obtained in Pricia variety with 8.96% (Table 2). Paydaş et al (2001), in their study on sixty-two natural apricot genotypes, stated that the pollens of these genotypes worked on agar-petri media containing 0.6% agar + 15 sucrose. They found that the germination strength varied between 79.19% (31K03) and 34.66% (Ablugoz).…”

Turkey is the leading country in the production of world apricots (Prunus armeniaca). In the country, apricots are usually grown for drying and fresh consumption, and apricots are also used for different purposes. This study was carried out to determine pollen viability and germination status in some foreign apricot varieties grown in Mut district of Mersin province, which has an important place in early ripening apricot production in Turkey. Pollen viability and germination ratios were determined by TTC and 1% agar 10% method in Mogador, Mikado, Pricia, Flopria apricot varieties. In terms of pollen values, the best result in terms of viable pollen is from the Mikado with 77.02% and Mogador varieties with 78.61%, while the Pricia variety with 44.09% in semi-viable pollen provides the most result, while Flopria and Pricia varieties produce the highest values in dead pollen results. In the germination tests, pollen germination rates were medium level in Flopria, Mogador and Mikado varieties the pollen germination rate of the Pricia variety is only 8.96%. The results obtained will be a guide in new orchard establishment and breeding studies.
