“…We previously used 4 mitochondrial minisatellite loci (TR1, TR2, TR3, and TR4; Nishizawa et al 2007) to analyze 748 individual plants from the leaf and garden beet groups or their close relatives. Among these we were able to distinguish 21 haplotypes, named min01 to min21 (Nishizawa et al 2007, Cheng et al 2011.…”

“…Individual plants were genotyped using the mitochondrial minisatellite loci TR1, TR2, TR3, and TR4 and some plants (see below) were also analyzed using the male-sterility-associated locus orf129 (Cheng et al 2009). The polymerase chain reaction (PCR) primers and procedures for amplification were as described by Cheng et al (2009Cheng et al ( , 2011. Polymorphisms were revealed using 2 % agarose gel or 4 % polyacrylamide gel electrophoresis, and visualized after ethidium bromide staining with known individuals as internal size standards.…”

Historically, sugar beets were selected from fodder beets. We used mitochondrial minisatellite loci to analyze cytoplasmic genetic diversity in fodder beet and sugar beet. Among the 8 sugar beet accessions examined we identified 3 multi-locus haplotypes. These 3 haplotypes were a subset of 5 haplotypes identified among the 29 fodder beet accessions examined. All but one haplotype in fodder beet comprised, in turn, a subset of 12 haplotypes identified previously in leaf beets. Such apparent decreases in cytoplasmic genetic diversity must result from genetic bottlenecks associated with domestication and the ensuing breeding processes. We also detected the haplotype associated with the male-sterile Owen cytoplasm of sugar beet in the fodder beet gene pool. Furthermore, the presence of a 39 kDa protein associated with the Owen cytoplasm was confirmed in two fodder beet plants by Western blot analysis. These results lead us to speculate that the Owen cytoplasm may have originated in fodder beet, from which sugar beet was derive

“…Landraces proved to be distinct from modern garden beet cultivars. Cheng et al (2010) investigated cytoplasmic genetic diversity in a set of 77 entries and concluded that (i) European leaf beet germplasm is the most diverse, (ii) North African leaf beets likely originate from Europe, (iii) leaf beet germplasm from the Middle East and western Asia is more similar to the European sources and (iv) East Asian germplasm is different from group (i) to (iv).…”

Conservation of the genetic resources of sugar beet has been considered a task of genebanks which collect, reproduce and preserve seed samples under cold storage conditions ex situ. 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. Conservation techniques complementing the ex situ approach are outlined. Conservation and use of genetic resources of any crop is to be based on knowledge of the taxonomy, the distribution of species, the genetic relationship between species and the intraspecific diversity. The geographic structure of genetic diversity within the sugar beet genepool is determined by the reproductive system of a species as well as the environmental factors acting as selective forces upon the species within its natural distribution area. An update of the current knowledge on the taxonomy, distribution, habitat, species relationships, and intraspecific diversity is given. How users can access germplasm held in genebanks and the descriptive data linked with the accessions is described. Finally deficits in germplasm conservation and information management are addressed and suggestions for the improvement of the sugar beet genetic resources management are made.

“…Leaf beet has never been bred intensively, thereby leading us to assume that a lot of variation is still present in leaf beet cultivars or landraces [6]. Leaf beet can be considered as a potential, valuable source of desirable characters lacking in sugar beet breeding programs [7]. With this in mind, we have decided to estimate the extent of genetic diversity within leaf beet germplasm resources.…”

Abstract. One mitochondrial minisatellite locus was used to study cytoplasmic diversity in leaf beet lines SK-5 population from Chongqing, China. The analysis of one mitochondrial minisatellite locus (TR2) was conducted using variable number of tandem repeats (VNTRs) molecular markers method within 50 single plants of leaf beet line SK-5 material. Over the whole sample, TR2 show the polymorphic with two alleles. The variable numbers of tandem repeats on TR2 locus is 3 and 6 respectively among the 50 plants examined. TR2 of a six-copy array of 33-bp sequence was first discovered in 2 single plants among the population. 1 plants can not bolting and 1 plant bolting late can not form normal seeds among the 2 plants which VNTRs copy number is 6. Only 1 plants among the 48 plants with three-copy in TR2 locus fails to bolting normally and others bolting normally and form seeds.
