“…The data also allow the identification of unknown cultivars and cases of synonyms. Our results were also in agreement with Liu et al (2015) who used ISSR markers to evaluate genetic diversity among 22 sweet kernel apricot accessions and 12 cultivars in China to provide information on how to improve the utilization of kernel apricot germplasms. The results showed that 9 ISSR primers amplified 67 allelic variants with 50 polymorphic bands (74.63%).…”

ncreasing the domestic consumption level is a very important issue as far as the future of hazelnut is considered (Sagra and Ozalp, 1988; Yucel, 1990). Velasco et al. (2016) stated that the domesticated almond [Prunus dulcis (L.) Batsch] and peach [P. persica (Mill.) D. A. Webb] originated in Asia and was independently domesticated. While inter-fertile, they possess alternate mating systems and differed in a number of morphological and physiological traits.

“…However, the contribution of the various wild Prunus species to the current Chinese cultivated germplasm has been little studied, or with insufficient sample sizes so far (Ai, Zhen, & Jin, 2011;Geuna, Toschi, & Bassi, 2003;Zhebentyayeva et al, 2008). Moreover, previous studies on the genetic diversity of Chinese species focused separately on cultivated (Li, Zhao, & Miao, 2014;Li et al, 2010;Liu, Du, Zhu, Fu, & Tana, 2015;Zhang et al, 2014) or wild apricots (He et al, 2007;Li, Zhao, Miao, & Zhou, 2013;Wang et al, 2014), without inferences on Chinese apricot domestication history.…”

Domestication is an excellent model to study diversification and this evolutionary process can be different in perennial plants, such as fruit trees, compared to annual crops. Here, we inferred the history of wild apricot species divergence and of apricot domestication history across Eurasia, with a special focus on Central and Eastern Asia, based on microsatellite markers and approximate Bayesian computation. We significantly extended our previous sampling of apricots in Europe and Central Asia towards Eastern Asia, resulting in a total sample of 271 cultivated samples and 306 wild apricots across Eurasia, mainly Prunus armeniaca and Prunus sibirica, with some Prunus mume and Prunus mandshurica. We recovered wild Chinese species as genetically differentiated clusters, with P. sibirica being divided into two clusters, one possibly resulting from hybridization with P. armeniaca. Central Asia also appeared as a diversification centre of wild apricots. We further revealed at least three domestication events, without bottlenecks, that gave rise to European, Southern Central Asian and Chinese cultivated apricots, with ancient gene flow among them. The domestication event in China possibly resulted from ancient hybridization between wild populations from Central and Eastern Asia. We also detected extensive footprints of recent admixture in all groups of cultivated apricots. Our results thus show that apricot is an excellent model for studying speciation and domestication in long‐lived perennial fruit trees.

“…ansu have primarily been based on phenotypic traits [ 4 , 14 ], but the morphological indexes are susceptible to environmental influences. With the rapid development and improvement of molecular biology techniques, AFLP [ 15 ], RAPD [ 16 ], SRAP [ 17 ], ISSR [ 18 ] and SSR have all been widely deployed in germplasm evaluation [ 19 ], genetic map construction [ 15 ], genetic diversity assessment [ 20 ], genetic relationship analysis [ 13 ], and population structure analysis [ 21 ] in the genus Prunus Mill. Germplasm provides important resources for exploring and protecting the genetic and phenotypic diversity of breeding applications.…”

The genetic diversity and genetic structure of P. armeniaca var. ansu were analyzed based on SSR markers. The aim was to provide scientific basis for conservation, efficient utilization, molecular marker assisted breeding and improved variety selection of P. armeniaca var. ansu germplasm resources. The results showed that the level of genetic diversity within the population was high. Among the 30 SSR markers, the mean number of observed alleles was 11.433, the mean number of effective alleles was 4.433, the mean of Shannon information index was 1.670, and the mean of polymorphic information content was 0.670. Among the eight provenances, Tuanjie Township, Xinyuan County, Xinjiang had the highest genetic diversity. The observed alleles, effective alleles, Shannon information index and Nei’s gene diversity index among provenances were higher than those within provenances. Based on Bayesian mathematical modeling and UPGMA cluster analysis, 86 P. armeniaca var. ansu accessions were divided into three subpopulations and four groups, which reflected individual differences in provenances. Subpopulations classified by Bayesian mathematical modeling and groups classified by UPGMA cluster analysis were significantly correlated with geographical provenance (Sig<0.01) and the provenances significantly impacted classification of groups. The provenances played an important role in classification of groups. The genetic distance between Tuanjie Township of Xinyuan County and Alemale Township of Xinyuan County was the smallest, while the genetic relationship between them was the closest and the degree of genetic differentiation was small.
