Fifteen strawberry germplasm collected from local and exotic sources were evaluated for different qualitative and quantitative characters. The germplasm showed variation for majority of the studied traits. Plant height during peak harvest ranged from 14.67 to 25.00 cm and FA 007 exhibited the tallest plants. The maximum number of leaves plant was produced by FA 006 (46.67). The maximum number o...

Harnessing diversity from germplasm collections is more feasible today because of the development of lower-cost and higher-throughput genotyping methods. However, the cost of phenotyping is still generally high, so efficient methods of sampling and exploiting useful diversity are needed. Genomic selection (GS) has the potential to enhance the use of desirable genetic variation in germplasm coll...

Phylogenetic relationships in the USDA Vigna germplasm collection are somewhat unclear and their genetic diversity has not been measured empirically. To reveal interspecific phylogenetic relationships and assess their genetic diversity, 48 accessions representing 12 Vigna species were selected, and 30 gene-derived markers from legumes were employed. Some high-quality amplicons were sequenced. I...

BACKGROUND E. arundinaceus (Retz.) Jeswiet is a warm-season, tall-growing perennial species native to much southern portion in China. The grass has been extensively used in sugarcane breeding and is recently targeted as a bioenergy feedstock crop. However, information on the genetic structure of the Chinese wild germplasm is limited. Knowledge of genetic variation within and among populations i...

SHATTERING Shattering can cause serious losses in commercial grain production of amaranth (Fitterer et al. 1996). In Nebraska, amaranth grain is harvested after the plants are killed by frost and have dried. The predominant cultivar ‘Plainsman’ is favored partly because it maintains good stem strength after frost has killed it (Baltensperger et al. 1992), however, it does shatter (Fitterer et a...

The Near East Fertile Crescent is well recognized as a primary center of barley origin, diversity, and domestication. A large number of wild barleys have been collected from the Tibetan Plateau, which is characterized by an extreme environment. We used genome-wide diversity array technology markers to analyze the genotypic division between wild barley from the Near East and Tibet. Our results c...

Salt stress causes significant reductions in rice production worldwide; thus, improving salt tolerance is a promising approach to meet the increasing food demand. Wild rice germplasm is considered a valuable genetic resource for improving rice cultivars. However, information regarding the improvement of salt tolerance in cultivated rice using wild rice genes is limited. In this study, we identi...

Characterization of natural allelic diversity and understanding the genetic structure and linkage disequilibrium (LD) pattern in wild germplasm accessions by large-scale genotyping of informative microsatellite and single nucleotide polymorphism (SNP) markers is requisite to facilitate chickpea genetic improvement. Large-scale validation and high-throughput genotyping of genome-wide physically ...

Rice and rice gene pool A cultivated rice (Oryza sativa L., referred to hereafter as rice) is an important world crop, providing staple foods for nearly one half of the global population. Achieving high productivity, including improved breeding methods, is always the challenge in meeting the demand for food security and nutritional sufficiency, particularly for the developing world. Apart from ...

Muscadine grape ( Vitis rotundifolia var. ) is a rare crop in that it has transitioned from wild fruiting plant to domesticated fruit within the past 150 years. Furthermore, this domestication process was carried out by just few institutions published copious records of origin and traits first selections, goals methods breeding programs, pedigrees releases. We thus have near complete record int...
