“…This wide variation is normal because plums are very complex groups including diploid, tetraploid and hexaploid species and because flower biology also differs in different plum groups (Ercisli, 2004). Prunus spinosa is allotetraploid (2n = 4x = 32; Reynders-Aloisi and Grellet, 1994). Allopolyploids are characterized by fixed (i.e., nonsegregating) heterozygosity, resulting from the combination of divergent parental genomes; bivalent formation occurs at meiosis, and disomic inheritance operates at each locus.…”

ABSTRACT. Prunus spinosa, blackthorn, exists as wild populations that inhabit uncultivated uplands of Coruh Valley in the northeastern part of Turkey; the fruit is used to make preserves. We examined genetic diversity in wild-grown Prunus spinosa; 16 individual plants from wild populations of Coruh Valley were sampled and subjected to RAPD (random amplified polymorphic DNA) analysis. We tested 51 random decamer primers; 15 of them gave reproducible polymorphic patterns. These 15 primers produced 226 bands, of which 65% were polymorphic. A UPGMA dendrogram clearly divided the genotypes into four groups; we concluded that RAPD analysis can be used for examining genetic relatedness among blackthorn genotypes.

“…This species is a wild amphidiploid (4x) hybrid from cross‐breeding of two diploid (2x) species, P . cerasifera and P. microcarpa (Eryomine, 1990; Salesses & Bonnet, 1993; Reynders‐Aloisi & Grellet, 1994). Natural hybrids (2 n = 40) with P. insititia have been recorded where morphological delimitation of the hybrid is impossible.…”

Summary• Current models for the generation of new gametophytic self-incompatibility specificities require that neutral variability segregates within specificity classes. Furthermore, one of the models predicts greater ratios of nonsynonymous to synonymous substitutions in pollen than in pistil specificity genes. All models assume that new specificities arise by mutation only.• To test these models, 21 SFB (the pollen S -locus) alleles from a wild Prunus spinosa (Rosaceae) population were obtained. For seven of these, the corresponding S -haplotype was also characterized. The SFB data set was also used to identify positively selected sites. Those sites are likely to be the ones responsible for defining pollen specificities.• Of the 23 sites identified as being positively selected, 21 are located in the variable (including a new region described here) and hypervariable regions. Little variability is found within specificity classes. There is no evidence for selective sweeps being more frequent in pollen than in pistil specificity genes. The S-RNase and the SFB genes have only partially correlated evolutionary histories.• None of the models is compatible with the variability patterns found in the SFB and the S -haplotype data.

“…Although this hypothesis was heretofore widely accepted, recent cytological studies have suggested that P. spinosa itself carries the genomic material from P. cerasifera as well as an unknown ancestor (Reynders-Aloisi and Grellet, 1994). Thus, hexaploid plums may have originated from polyploid forms of P. cerasifera (Reynders and Salesses, 1991).…”

A B S T R A C TPlum seedlings are extensively used as rootstocks for stone fruits except P. cerasus. Genetic diversity in seedlings used for rootstocks might result in variation of scion performance and subsequently non-uniform orchards. This study aimed on investigating variation among several Iranian plum genotypes sampled from seedlings grown for grafting. Thirty-five 3-to 4-year-old seedlings were characterized using 28 quantitative and qualitative traits, as well as 22 RAPD markers. Results of the morphological study revealed remarkable variability in studied traits. Genotypes were separated into three different groups according to their height using cluster analysis performed by Ward's clustering method based on morphological data. Twenty two RAPD primers from 120 screened produced 195 polymorphic reproducible bands (86.75% polymorphism). According to the similarity matrix, the lowest similarity was obtained between the genotype Tansgol (control) and S4-13 and the highest similarity between S11-25 and S11-26. According to the cluster analysis based on Jaccard's similarity coefficients and the UPGMA method at a similarity level of 0.56, the genotypes were divided into six sub-clusters. Significant association between eight morphological traits with RAPD markers was found by marker association analysis done using multiple linear regressions. The application of the methodology in screening elite genotypes is discussed.
