“…In addition, AFLPs were used in determining that the genetic diversity is higher in homogamous than in dichogamous genotypes, due to a higher level of heterozygosity (Sütyemez 2006). Then, Turkish J. regia trees were characterized using AFLPs in order to select superior genotypes (Kafkas et al 2005) and AFLPs were used to study the genetic diversity among Turkish genotypes with a low chill requirement (Bayazit et al 2007). In China, wild J. regia and J. sigillata populations from Sichuan province were studied using AFLPs to understand the genetic relationships between these two economically important species in the province (Chen et al 2008(Chen et al , 2009).…”

Persian or English walnut (Juglans regia L.), the walnut species cultivated for nut production, is one of the oldest food sources known. Persian walnuts, native to the mountain valleys of Central Asia, are grown worldwide in temperate areas. World production exceeds three million tons since 2012, mostly provided by China, the USA, and Iran. Despite very ancient culture of walnut species (Juglans spp.), breeding actually started in the twentieth century. Using a range of methodologies, from morphological markers to the most recent advances in genome analysis, many genetic studies of walnut have been conducted during the past 30 years, including examination of diversity, determination of relationships within or among germplasm collections and populations, phylogenetic and origin elucidation, genetic map construction, and biotic or abiotic stress investigations. The genetic improvement of walnut has undergone great evolution. The producing countries of the Middle East have widely studied morphological characteristics of walnut. The USA and France, for example, are behind important cultivar releases such as BChandler^and BFranquette.^Finally, genomics represents a major breakthrough in walnut improvement, in particular by recent sequencing of both chloroplast and nuclear genomes. This review summarizes worldwide molecular and Bomics^studies and gives an overview of the main walnut breeding programs.

“…Previously, in addition to morphological identification (Zenelli et al 2005), various biochemical and molecular markers have been used for genetic characterization of walnut genotypes. These included isozymes (Fornari et al 2001;Busov et al 2002;Ninot and Aleta 2003;Vyas et al 2003,), restriction fragment length polymorphisms (RFLPs) (Fjellstrom et al1995), randomly amplified polymorphic DNAs (RAPDs) (Nicese et al1998;Yan-Min et al 2000;Zhang Li et al 2007), intersimple sequence repeats (ISSRs) (Potter et al 2002), simple sequence repeats (SSRs) Dangl et al 2005;Foroni et al 2005;Victory et al 2006;Robichaud et al 2006;Karimi et al 2010), amplified fragment length polymorphisms (Kafkas et al 2005;Bayazit et al 2007) and SNPs (Ciarmiello et al 2011). In our study, the average number of alleles per locus was 2 which is higher than 1.3 detected in J. regia with RAPDs (Nicese et al 1998) but lesser than 3.9 and 5.5 using ISSR (Potter et al 2002) and SSR (Foroni et al 2007) markers respectively.…”

In this study, genetic diversity was assayed among 16 accessions and five cultivars of Persian walnut (Juglans regia L.) using morphological traits and nine simple sequence repeat (SSR) markers. Samples were collected from Agriculture Research Center of Urmia city (North West Iran). Study on important morphological traits revealed genetic similarity of -0.6 to 0.99 based on CORR coefficient. The microsatellite marker system produced 34 alleles in range of 160-290 bp. The minimum (2) and maximum (7) number of alleles were obtained from WGA71 and WGA202 genetic loci, respectively. The mean number of alleles per locus was 4.25. Jaccard’s similarity coefficient ranged from 0.13 to 0.76. The results of this paper indicate high diversity among these genotypes which could be used for breeding management.
