“…The average expected heterozygosity was 0.68 for perennials, 0.65 for heterozygotes and 0.61 for wind-borne plants [29]. The genetic diversity of the 15 seed sources of M. azedarach in this study was at a moderate level, slightly lower than in previous related studies [30]. The different sources of SSR used, the number of primers, and the small sample size collected from some of the seed sources in this study may have contributed to these differences.…”

Melia azedarach L. is a native tree species that can be used in a comprehensive way and is widely distributed in all provinces south of the Yellow River in China. Genetic diversity analysis of different M. azedarach germplasm sources is an important basic work for the selection, evaluation, and genetic improvement of M. azedarach germplasm resources. In this study, 100 pairs of SSR primers were designed and synthesized based on M. azedarach transcriptome data, and 16 pairs of reliable SSR primers were finally selected. The developed primers were used to analyze the genetic diversity of M. azedarach from 15 sources in 10 provinces in East, Central, and South China. The results showed that the frequency of the M. azedarach transcriptome SSR loci was high, and the distribution density was high. There were 15 sources of M. azedarach genetic diversity at a moderate level, and genetic variation was mainly present within the sources. The present study further enriches the existing SSR marker database of the M. azedarach family and can provide a reference for genetic diversity analysis and molecularly assisted breeding of M. azedarach plants at the genomic level.

“…Another indicator is population structure, which is the distribution pattern of genes and genotypes in time and space, which is informative for understanding genetic diversity [16]. Studying the genetic diversity and population structure of forest trees with a long life cycle, a wide distribution, and high ecological and economic value is of great significance for genetic resource conservation and forest ecosystem management [13,[17][18][19].…”

Studying the genetic diversity and population structure of natural forest populations is essential for evaluating their ability to survive under future environmental changes and establishing conservation strategies. Pinus koraiensis is a conifer species with high ecological and economic value in Northeast China. However, its natural forests have been greatly reduced in recent years, mostly due to over exploitation and over utilization. Here, we evaluated the genetic diversity and population structure of seven populations of P. koraiensis located throughout its native distribution. A total of 204 samples were genotyped with nine polymorphic nuclear SSR (simple sequence repeat) markers. The results showed high genetic diversity in all populations, with an average expected heterozygosity of 0.610, and the northern-most populations (Dailin (DL) and Fenglin (FL)) showed slightly higher diversity than the other five populations. The level of genetic differentiation among populations was very low (FST = 0.020). Analysis of molecular variance (AMOVA) showed that only 2.35% of the genetic variation existed among populations. Moreover, STRUCTURE analysis clearly separated the seven populations into two clusters. Populations DL and FL from the Xiaoxinganling Mountains comprised cluster I, while cluster II included the five populations from the Changbai Mountains and adjacent highlands. Our research on the genetic diversity and population structure of P. koraiensis in natural forests of China can provide a basis for the implementation of programs for the conservation and utilization of P. koraiensis genetic resources in the future.

“…According to Yulianti (2011), Genetic diversity of Melia azedarach in community forests of West Java assessed by RAPD marker (He: 0.1603 -0.1956) categorized as moderate. Thakur (2016) found genetic diversity and population structure of Melia azedarach in North-Western Plains of India assessed by microsatellite marker (He = 0.712) categorized as high diversity Genetic quality needs to be considered because it is related to with the capacity to adapt to the growth environment. The higher the genetic diversity showed that the plant has greater chance to adapt to the environment change.…”

“…Genetic diversity in a species allows itself to adapt, evolve and respond to environmental stress. It provides the basis for survival of a species and critically influences its evolutionary potential (Thakur 2016). The genetic diversity status of species can be determined using several molecular methods such as isoenzymes, RAPD, and microsatellite.…”

Abstract. Rambey R, Susilowati A, Anna N. 2019. Genetic diversity of mindi (Melia azedarach) from community forest in Deli Serdang, North Sumatra, Indonesia revealed by microsatellite marker. Biodiversitas 20: 1708-1712. Melia azedarach or locally known as mindi is fast growing and one of important tree species for community forests especially in West Java and North Sumatra, Indonesia. High demand for its wood must be accompanied by increased productivity through planting of high-quality seed. There is still lack of information about genetic diversity of mindi from different seed source in North Sumatra. Therefore, our research was conducted to determine genetic diversity of mindi from different seed source in North Sumatra through microsatellites marker. Leaf samples originated from three populations Percut Sei Tuan, Pancur Batu and Biru-Biru were used in this study. The SSR markers were from Azadirachta indica i.e. Ai5, Ai 11, Ai 13, Ai 14 and Ai 34. Molecular data were analyzed using Popgene and NTsys version 2.0. The result showed that number of alleles (na) ranging from 1.80 to 2.80, and percentage of polymorphic loci (PPL) ranging from 60 to 80 %. The level of genetic diversity showed that mindi in North Sumatra has moderate value (He: 0.244 to 0.269). It indicated that assessment of genetic diversity of M. azedarach North Sumatra is necessary for improvement and conservation of a species.
