“…In addition to the structural differences among kiwifruit cultivars, the results of genetic diversity analysis are also different due to the different primers selected. The average Si (1.12) and Nd (0.566) in this study were higher than those of previous studies on some kiwifruit germplasm materials (Zhang et al, 2017;Lang, 2016;Sui et al, 2013;Liu et al, 2015). On the one hand, it is possible to use different molecular marker techniques or SSR loci selecloci.…”

In order to explore the genetic diversity of wild Actinidia eriantha resources in Magu Mountain Nature Reserve, Nancheng County, Fuzhou City, Jiangxi Province of P.R. China, 145 wild A. eriantha germplasm resources were collected and used as tested materials. This research designed 40 SSR primers to amplify DNA of young leaf. A total of 224 alleles were obtained and the number of alleles of primers were ranged from 3 to 13. The average number of effective alleles was 2.83, the average Shannon's information index was 1.12, the average Nei's gene diversity index was 0.566, the average apparent heterozygosity was 0.54, and the average expected heterozygosity was 0.57. The results indicated that there were abundant variations among different substances in wild A. eriantha. In addition, the cluster analysis showed that the materials were divided into 13 groups at the genetic distance of 0.099, among them, the XIII group accounted for 81.38% of the total. This study would provide theoretical basis for the breeding of novel cultivars of A. eriantha and the genetic improvement of fruit quality.

“…through phenotypic identi cation, and it was hypothesized that the use of traditional identi cation methods combined with molecular marker technology could more accurately express species a nities. 'Korla fragrant pear' and Xinjiang pear 'Yili red sentence pear' clustered together, which was inconsistent with the identi cation results of Lu Fengjuan [34] who used AFLP molecular markers, and found that 'Korla fragrant pear' is more closely related to western pear'.. 'Nesiput' was clustered with Xinjiang pear 'Kuche Amut', which should be attributed to Xinjiang pear. 'Kot Amut', which is usually regarded as Xinjiang pear, was clustered with the western pear 'Yalik Amut', which was regarded as belonging to the western pear.…”

Background To elucidate the genetic basis of local pear varieties in Xinjiang, China, this study was conducted to scan the whole genome of 28 local pear varieties in Xinjiang using single nucleotide polymorphism (SNP) molecular marker technology and analyze their genetic diversity and population structure. Result The pure SNP polymorphic loci obtained through screening were 2,045,692, which basically covered the pear genome. The genetic similarity coefficients between the varieties ranged from 0.3086 to 0.9977; when K = 4, the 28 varieties were divided into four groups, and there was general gene exchange between the populations. The cluster analysis results showed that the 28 varieties were classified into 4 taxa. The PCA results also divided the test material into 4 groups, which deviated from the evolutionary tree. The largest number of populations was found in pears between 2 and 10 million years ago, during which the reproductive development of pears developed rapidly. Conclusions The study showed that SNPs obtained polymorphism information among different pear varieties at the genome-wide level, which can be used for genetic diversity analysis between varieties and provide a reference for future molecular enhancement of pear breeding and systematic conservation of plant genetic resources.

Pinus cembroides es el pino piñonero con la más amplia distribución e importancia económica y social en México. El objetivo del presente estudio fue evaluar los niveles y patrones de variación genética de ocho poblaciones de P. cembroides de la región central de México mediante marcadores ISSR (Inter-secuencias simples repetidas). Las poblaciones se distribuyen en dos provincias fisiográficas, la Sierra Madre Oriental y la Mesa del Centro. Los iniciadores utilizados generaron un total de 154 bandas, de las cuales 88.3 % fueron polimórficas a nivel de especie. La diversidad genética promedio en las poblaciones fue alta (He = 0.22), el porcentaje de polimorﬁsmo promedio fue 59.2 %. Los parámetros de diversidad genética fueron más altos en las poblaciones de la Sierra Madre Oriental. La mayor parte de la diversidad genética se encontró dentro de las poblaciones (74 %) y sólo el 26 % entre éstas. De acuerdo con el valor de GST = 0.28, existe alta diferenciación entre las poblaciones. El nivel de flujo génico, considerado como el número de individuos migrantes, fue bajo (Nm = 1.27) entre las poblaciones en las dos regiones. Se encontró baja pero significativa correlación entre la distancia geográfica y la distancia genética de las poblaciones en las dos regiones.
