Sugar beet (Beta vulgaris L. ssp. vulgaris) is one of the most important European crops for both food and sugar production. Crop improvement has been developed to enhance productivity, sugar content or other breeder's desirable traits. The introgression of traits from Crop Wild Relatives (CWR) has been done essentially for lessening biotic stresses constraints, namely using Beta and Patellifolia species which exhibit disease resistance characteristics. Several studies have addressed crop-to…

Molecular Breeding Strategies of Beetroot (Beta vulgaris ssp. vulgaris var. conditiva Alefeld)

This chapter provides an overview and limitations of the beetroot germplasm biodiversity and conservation, objectives and stages of beetroot breeding programs and conventional breeding methods, and addresses modern methods of plant breeding, including marker-assisted breeding and genetic engineering.

Exploitation of epigenetic variation of crop wild relatives for crop improvement and agrobiodiversity preservation.

There is emerging evidence that epigenetic variants of functional and/or agronomic importance exist in CWR gene pools, providing a rationale for the conservation of epigenotypes of interest, thus contributing to agrobiodiversity preservation through conservation and (epi)genetic monitoring.

Genomic distances reveal relationships of wild and cultivated beets

Genomic comparisons based on k-mers identify sea beets from Greece as the closest wild relatives of sugar beet, suggesting that domestication of the ancestors of Sugar beet may be traced to this area.

Elucidation of genetic diversity among some accessions of sugar beet (Beta vulgaris L.) using inter-simple sequence repeats (ISSR) markers

Background Sugar beet is considered a very important strategic economic crop, as it comes at the second place for white sugar production in Egypt after sugar cane and the sugar percentage in its

Assessment of sugar beet genetic diversity in the Republic of Kazakhstan by using RAPDmarkers and agromorphological traits

Sugar beet is a highly valuable and profitable crop in the Republic of Kazakhstan. It is the only source of raw materials for the production of crystalline sugar and incidentals (tops, bagasse, and

Tapping Diversity From the Wild: From Sampling to Implementation

How technological advances in genomics, phenomics, biotechnology, and data science can improve the ability to identify beneficial genetic variation in CWRs and to exploit it in strive for higher-yielding and sustainable crops is discussed.

Assessment of interspecific hybridization between wild beet Beta vulgaris L. subsp. maritima and cultivated sugar beet under Moroccan conditions

The results showed the success of interspecific beet crosses and emphasized the high variability among hybrid genotypes, of great importance for sugar beet improvement and breeding programs and interspecific crosses patterns understanding.

Seeds of Success: Collateral Benefits to Agricultural Crop Improvement, Research, and Education

The SOS National Collection was evaluated for potential as sources of traits for crop improvement and direct development for agricultural purposes and use of the collection was examined using information provided in seed requests from the USDA National Plant Germplasm System.

Genomes of the wild beets Beta patula and Beta vulgaris ssp. maritima.

We present draft genome assemblies of Beta patula, a critically endangered wild beet endemic to the Madeira archipelago, and of the closely related Beta vulgaris ssp. maritima (sea beet).

The effect of heat stress on sugar beet recombination

The potential use of heat stress to foster recombination in sugar beet breeding programmes is supported, with changes were mainly induced by alterations in female meiosis only, showing that heterochiasmy in sugar Beet is reduced under heat stress.



Biodiversity Assessment of Sugar Beet Species and Its Wild Relatives: Linking Ecological Data with New Genetic Approaches

This review has focused on EcoTILLING as a molecular tool to assess DNA polymerphisms in wild populations of Beta and identify candidate genes related to drought and salt tolerance, as well as addressed some issues related to next-generation sequencing (NGS) technologies.

Crop wild relative populations of Beta vulgaris allow direct mapping of agronomically important genes

The results show the importance of preserving CWR in situ and demonstrate the great potential of CWR for rapid discovery of causal genes relevant for crop improvement, and open the path to improvement of resistance towards rhizomania.

Genetic Diversity and Physiological Performance of Portuguese Wild Beet (Beta vulgaris spp. maritima) from Three Contrasting Habitats

Two striking ecotypes are VMT, which is the best to cope with drought and salinity, and CMP which has the highest root to shoot ratio, which emphasize the importance of the wild beet ecotypes for beet improvement programs.

Back into the wild—Apply untapped genetic diversity of wild relatives for crop improvement

This review highlights the significance of crop wild relatives for crop improvement by providing examples of CWRs that have been used to increase biotic and abiotic stress resistance/tolerance and overall yield in various crop species, and discusses the surge of advanced biotechnologies, such as next‐generation sequencing technologies and omics.

The genome of the recently domesticated crop plant sugar beet (Beta vulgaris)

A reference genome sequence for sugar beet is presented as the first non-rosid, non-asterid eudicot genome, advancing comparative genomics and phylogenetic reconstructions and provides evidence for the separation of Caryophyllales before the split of asterids and rosids, and revealed lineage-specific gene family expansions and losses.

Molecular assessment of genetic diversity in winter barley and its use in breeding

First results on a project aiming on a genome wide estimation of genetic diversity which in combination with data on yield and additional agronomic traits may facilitate the detection of marker trait associations and a more efficient selection of parental genotypes are presented.

Identification and exploitation of novel disease resistance genes in sugar beet.

This review describes an IACR-Broom's Barn programme devoted to evaluating Beta germplasm for novel resistance to major viral and fungal diseases, and its progress in elucidating the numbers and locations of the genes responsible.

Conservation and Access to Sugarbeet Germplasm

Arguments are provided why the ex situ conservation of beet germplasm may not be fully sufficient to maintain the genetic diversity of beet genetic resources on the long run and suggestions for the improvement of the sugar Beet genetic resources management are made.

Genetic evidence for the origin of Californian wild beets (genus Beta)

Genetic variation in 64 germplasm accessions of wild and domesticated beets and the origin of wild beet accessions in California using allozyme analysis showed overall that domesticated and wild beets form genetically coherent groups.

Genetic mechanisms of abiotic stress tolerance that translate to crop yield stability

An effective new paradigm is the targeted identification of specific genetic determinants of stress adaptation that have evolved in nature and their precise introgression into elite varieties.
