Poor grain plumpness (GP) is one of the main constraints to reaching the yield potential of hybrid rice. In this study, the GP of 177 rice varieties was investigated in three locations across 2 years. By combining the genotype data of 261 simple sequence repeat (SSR) markers, association mapping was conducted to identify the marker-GP association loci.

Assessment of genetic diversity of Vigna unguiculata (L.) Walp (cowpea) accessions using informative molecular markers is imperative for their genetic improvement and conservation. The reproducible bands were scored for analyses of dendrograms, principal component analysis, genetic diversity, allele frequency, polymorphic information content, and population structure.

Rice is one of the most important food crops in the world and mainly cultivated in paddy feld by transplanting seedlings. However, increasing water scarcity due to climate change, labor cost for transplanting, and competition from urbanization is making this traditional method of rice production unsustainable in the long term.

Korarima [Aframomum corrorima (Braun) P.C.M. Jansen] is a spice crop native to Ethiopia. Understanding the extent and partitioning of diversity within and among crop landraces and their wild relatives is among the first steps in conserving and measuring their genetic potential. The present study is aimed at characterizing the population genetic structure and relationships between cultivated and wild korarima in the southwestern part of Ethiopia.

Archeological and historical evidence indicated the presence of this species in Southeast Asia dating back at least 1500 years. B. flabellifer is believed to be originated in Africa, spread to South Asia and introduced into Southeast Asia through commercial routes and dissemination of cultures, however, the nature of its invasion and settlement in Thailand is unclear.

Breonadia salicina (Rubiaceae) is a critically endangered plant at the local scale native to southwestern Saudi Arabia. To understand the levels and partitioning of genetic variation across populations and geographical regions of this species, we assessed its genetic diversity using inter-simple sequence repeat (ISSR) markers.

Ampelopsis grossedentata is an important national medicine in China. It is mainly used commonly by the Yao, Miao, Dong, and other ethnic minorities of China. The current literature, however, contains no study on the molecular genetics and taxonomy of A. grossedentata, which had led to potential problems in the conservation and utilization of this resource. Therefore, the present study was aimed to use simple sequence repeat (SSR) markers for assessing the levels and the distribution of genetic diversity in a sample set of 225 individuals from nine populations of A. grossedentata in China.

In this study, we aimed to understand the genetic structure of 440 individual wild cherries sampled from 22 different populations in Turkey using 10 SSR molecular markers. With the molecular variance analysis, we found that the genetic diversity within the population is approximately 88.5% and the genetic diversity among the populations is approximately 9.8%. Thus, wild cherry genetic diversity within populations is high whereas it is moderate between tested populations (FST values 0.02-0.16).

Plectranthus edulis (Vatke) Agnew (locally known as Ethiopian dinich or Ethiopian potato) is one of the most economically important edible tuber crops indigenous to Ethiopia. Evaluating the extent of genetic diversity within and among populations is one of the first and most important steps in breeding and conservation measures.

The study "Characterization of grapevine (V. vinifera L.) varieties grown in Yozgat province (Turkey) by simple sequence repeat (SSR) markers" was conducted to characterise 50 grape varieties grown in Yozgat by molecular methods. Molecular definitions were realized using 9 simple sequence repeat (SSR) primers (VVS2, VVMD5, VVMD7, VVMD24, VVMD27, VVMD28, VVMD31, VrZAG62, and VrZAG79), including six microsatellite loci used for grapevine variety collections by the European Union funded project (GENRES 081), accepted as the minimum standard set (core set) by the world.

The study aims to evaluate the genomic diversity of some local melientha suavis Pierre SSR technique. By using 10 primer pairs to analyze 20 melientha suavis Pierre lines shows that the number of Alleles were from 2 to 4 alleles and the polymorphic information contents ranged from 0.05 to 0.15. Forty-one alleles were identified with avarage of 0.15 alleles.

The objective of this study was to assess morphological and genetic diversities of 48 forage pea landraces collected from different locations at different altitudes in Turkey. Morphological, quality, and yield features were determined for the landraces and three control cultivars in three subsequent years. Genetic diversities of the landraces and cultivars were also monitored using microsatellite (SSR) markers. Our results revealed that the features of landraces are significantly different.

Medicago ciliaris (L.) Krock and Medicago intertexta (L.) Mill are most often found in saline regions and are considered as potential resources for genes related to salinity resistance. To explore the genetic diversity of these two species by mean of nrSSR (simplesequence repeats) markers, 11 accessions originated from different regions in north of Africa and Middle East were chosen. Ten among 14 markers turned out to be polymorphic and gave 72 alleles. Eight markers were very informative with PIC values > 0.5, and three of them were found to be nonneutral.
