Snake melon (Cucumis melo var. flexuosus, “Faqqous”) is a traditional and ancient vegetable in the Mediterranean area. A collection of landraces from 42 grower fields in Israel and Palestinian territories was grown and characterized in a “Common Garden” rain-fed experiment, at the morphological-horticultural and molecular level using seq-DArT markers.

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.

The ability of maize populations/landraces to tolerate drastically extreme environments over the past four centuries in Algeria leads to characterize these genetic resources for germplasm management as well as the identification of the best landraces useful for genetic improvement.

Stripe rust is a serious fungal disease of wheat (Triticum aestivum L.) caused by Puccinia striiformis f. sp. tritici (Pst), which results in yield reduction and decreased grain quality. Breeding for genetic resistance to stripe rust is the most cost-effective method to control the disease.

Reproductive performance is critical for efficient swine production. Recent results indicated that vulva size (VS) may be predictive of reproductive performance in sows. Study objectives were to estimate genetic parameters, identify genomic regions associated, and estimate genomic prediction accuracies (GPA) for VS traits.

Tunisia is considered a secondary center of diversification of durum wheat and has a large number of abandoned old local landraces. An accurate investigation and characterization of the morphological and genetic features of these landraces would allow their rehabilitation and utilization in wheat breeding programs.

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.

Research to identify and characterize stem rust resistance genes in common wheat, Triticum aestivum, has been stimulated by the emergence of Ug99-lineage races of the wheat stem rust pathogen, Puccinia graminis f. sp. tritici (Pgt), in Eastern Africa. The Montenegrin spring wheat landrace PI 362698 was identified as a source of Pgt resistance. This accession exhibits resistance to multiple Ug99-lineage and North American Pgt races at seedling and adult-plant stages.

Molecular characterization of submergence tolerance genes and locus in the deep-water rice cultivars
In this study, we focus on characterize the genetic variation at the Sub1 locus and to associate its relevance, if any, to submergence tolerance among the deep water landraces. As a first step, seeds of some rice cultivars collected from North-east Indian regions were initially selected for the characterization of genetic variation. The PCR based analysis involving several genes known to be associated with submergence tolerance did not reveal much difference.

A hundred landraces of rice (Oryza sativa L.), from core group genotypes collected from different parts of Chhattisgarh, were characterized following the guidelines from the Protection of Plant Varieties and Farmers' Rights Authority, GOI. Hundred rice accessions were planted in a randomized block design (RBD).

In the late 1920s, A. E. Watkins collected about 7000 landrace cultivars (LCs) of bread wheat (Triticum aestivum L.) from 32 different countries around the world. Among which 826 LCs remain viable and could be a valuable source of superior/favorable alleles to enhance disease resistance in wheat.

In the present study, sixty four aromatic landraces of rice collected from different districts of Madhya Pradesh were analysed for genetic variation using SSR markers. Specially, the objective of the study was DNA fingerprinting and genetic diversity analysis of aromatic landraces to requisite to study the unique feature and to identify the duplication among them and to assist in broadening the germplasm base of future aromatic rice breeding programs. Very high variation was observed for the trait sterile lemma colour in the classes of straw (76.56%), purple (10.94%), gold (7.81%) and 4.

An investigation was carried out to know the extent of genetic variability present in ten Chakhao rice (scented rice) of Manipur during kharif 2017. Ten Chakhao landraces namely Wairi chakhao, Khurkhul chakhao, Khunou chakhao, Chakhao sempak, Pong chakhao, Chetemo, Chakhao angangbi, Heimang chakhao and two Chakhao poireiton samples (from different locations) were taken for the experiment.

Thirty different wheat genotypes, including landraces, cultivars, and related wild species, were analyzed for puroindoline genes and proteins. Full-length Pina and Pinb genes were amplified using gene-specific markers where 13 genotypes amplified both genes, while 17 genotypes had either one or none of the puroindoline genes.

Genetic variations are the raw materials of plant breeding and have been increasingly narrowed due to various reasons. Landraces are good sources of genetic variation, but need to be characterized first.
