Clarifying genetic diversity in a large germplasm resource plays important roles in experimental designs that provides flexible utility in fundamental research and breeding in crops. However, the work is limited due to small collections of barley that are insufficient representatives.

High-density single nucleotide polymorphisms (SNPs) are the most abundant and robust form of genetic variants and hence make highly favorable markers to determine the genetic diversity and relationship, enhancing the selection of breeding materials and the discovery of novel genes associated with economically important traits.

The Elaeis oleifera genetic materials were assembled from its center of diversity in South and Central America. These materials are currently being preserved in Malaysia as ex situ living collections. Maintaining such collections is expensive and requires sizable land. Information on the genetic diversity of these collections can help achieve efficient conservation via maintenance of core collection.

Genetic diversity provides the capacity for plants to meet changing environments. It is fundamentally important in crop improvement. Fifty-nine local maize lines developed at INERA and 41 exotic (temperate and tropical) inbred lines were characterized using 1057 SNP markers to (1) analyse the genetic diversity in a diverse set of maize inbred lines; (2) determine the level of genetic diversity in INERA inbred lines and patterns of relationships of these inbred lines developed from two sources; and (3) examine the genetic differences between local and exotic germplasms.

Sainfoin is a perennial forage legume with beneficial properties for animal husbandry due to the presence of secondary metabolites. However, worldwide cultivation of sainfoin is marginal due to the lack of varieties with good agronomic performance, adapted to a broad range of environmental conditions.

Conservation of genetic diversity is an essential prerequisite for developing new cultivars with desirable agronomic traits. Although a large number of germplasm collections have been established worldwide, many of them face major difficulties due to large size and a lack of adequate information about population structure and genetic diversity.

The aim of the present study was to examine the diversity for heat tolerance in a set of 105 accessions using some key morphophysiological attributes. The data was standardized by calculating percent change over control, and used for phonetic analysis and construction of dendograms based on distance matrix (all primary data is given as supplementary material listed in statistical analysis section of Materials and Methods).

"Genome-wide association studies (GWAS) revealed a genetic basis associated with floral traits in potato germplasm" aimed to explore the phenotypic diversity and to identify the genetic basis associated with important floral traits. A total of 237 tetraploid potato genotypes were used as plant material, and field experiments were conducted according to augmented block design for two consecutive years (2016, 2017).

The aim of the study "Characterization of some local pea (Pisum sativum L.) genotypes for agro-morphological traits and mineral concentrations" is to evaluate diversity among the Turkish local pea germplasm for mineral concentrations and agro-morphological traits for breeding programs. The experiment was conducted during 2018/2019 and 2019/2020 and arranged according to an augmented block design with 40 local genotypes and two standard check cultivars (Carina and Jof).

In this study, the genotypes of melon in Kyrgyzstan were collected by visiting several regions and contacting farmers. The genetic diversity of 35 Kyrgyz and 13 Turkish melon accessions was characterized based on the corresponding phenotypes. The morphological characterizations were largely based on the IPGR and, to some extent, UPOV standards.

Information on population structure and genetic diversity of germplasm in a breeding programme is useful because it enhances judicious utilisation of genetic resources to achieve breeding objectives. Seventy early maturing provitamin A (PVA) quality protein maize (QPM) inbreds developed by the IITA- maize improvement programme were genotyped using 8171 DArTseq markers.

"Evaluation of Lonicera caerulea L. genotypes based on morphological characteristics of fruits germplasm collection" is known that a polymorphic population consisting of a large number of genotypes adapts more rapidly to the environment conditions. The availability of a large gene pool predetermines the success of the introduction and further breeding of new cultivars with economically valuable features. Morphometrics is a classical tool for studying the amplitude of the variability of cultivated plants and evaluating the genotypic diversity of the artificial population.

Productivity of cowpea [Vigna unguiculata (L.) Walp] in sub-Sahara Africa is curtailed by a lack of farmer-preferred and improved cultivars and modern production technologies. The objectives of the study were to determine the extent of genetic diversity present among a collection of cowpea accessions from Zambia and Malawi using phenotypic traits and single nucleotide polymorphism (SNP) markers and, to select distinct and complementary parental lines for cultivar development.

High salinity is a devastating abiotic stresses for crops. To understand the molecular basis of salinity stress in yardlong bean (Vigna unguiculata ssp. sesquipedalis), and to develop robust markers for improving this trait in germplasm, whole transcriptome RNA sequencing (RNA-seq) was conducted to compare the salt-tolerant variety Suzi 41 and salt-sensitive variety Sujiang 1419 under normal and salt stress conditions.
