“…In addition, we obtained some small linkage groups, the same as in Juglans regia [31]. These phenomena have been found in many species [16,18,31,33,40,41] and indicate that some gaps prevent connection between linkage groups belonging to the same chromosome, which needs to be optimised in the future by expanding mapping population, increasing parental combinations and adopting new markers. By contrast with the variety of mapping populations in crops [42,43], the growth cycle of trees was long, and the genetic offspring was difficult to be obtained.…”

“…The markers used in this study were also obtained from the transcriptome database, and 4.87% segregation distortion (SD) were detected, which was lower than for Castanea sativa (sweet chesnut) [18], Populus spp. (poplar) [30], Juglans regia (walnut) [31], Ziziphus jujuba (jujube) [32] and Citrus clementina (clement pomelo) [33]. Segregation distortion is a common problem in population mapping, and a number of variables could have led to SD [34][35][36][37][38].…”

“…By contrast with the variety of mapping populations in crops [42,43], the growth cycle of trees was long, and the genetic offspring was difficult to be obtained. The F1 mapping population is the most common one, and abundant variation can be gained through interspecific hybridisation in many trees [18,33]. In E. ulmoides, parents with significant differences should be valued.…”

Eucommia ulmoides (Tu-chung) is an economically and ecologically important tree species which has attracted worldwide attention due to its application in pharmacology, landscaping, wind sheltering and sand fixation. Molecular marker technologies can elucidate the genetic mechanism and substantially improve the breeding efficiency of E. ulmoides. The current research updated the original linkage map, and quantitative trait loci (QTL) analysis was performed on tree growth traits measured over 10 consecutive years in an E. ulmoides F1 population (“Xiaoye” × “Qinzhong No.1”). In total, 452 polymorphic markers were scored from 365 simple sequence repeat (SSR) primers, with an average of 1.24 polymorphic markers per primer combination. The integrated map was 1913.29 cM (centimorgan) long, covering 94.10% of the estimated genome and with an average marker density of 2.20 cM. A total of 869 markers were mapped into 19 major independent linkage groups. Growth-related traits measured over 10 consecutive years showed a significant correlation, and 89 hypothetical QTLs were forecasted and divided into 27 distinct loci. Three traits for tree height, ground diameter and crown diameter detected 25 QTLs (13 loci), 32 QTLs (17 loci) and 15 QTLs (10 loci), respectively. Based on BLASTX search results in the NCBI database, six candidate genes were obtained. It is important to explore the growth-related genetic mechanism and lay the foundation for the genetic improvement of E. ulmoides at the molecular level.

Haploid and doubled haploid (DH) plants are of great value for genetic analyses and premeditated breeding. This is especially true for woody species, which are generally characterized by a long reproductive cycle, a high degree of heterozygosity, a large plant size, and self-incompatibility. In Citrus and related genera, some haploid and DH plants have been produced by techniques such as anther culture, interploid hybridization, and the pollination of irradiated pollen. However, there are few reports of the characteristics of haploid and DH plants' flowers, fruits, or reproductive potential. We selected a haploid progeny among small seed-derived seedlings obtained from 'Banpeiyu' pummelo [C. maxima (Burm.) Merr.], and we produced the DH plant of this haploid using colchicine-treated axillary shoot buds. Both this haploid pummelo and the DH pummelo showed normal growth and produced many flowers and fruit. In this chapter, we describe about the morphological characteristics and the reproductive potential of the haploid pummelo and the DH pummelo.

“…The International Union for the Protection of New Varieties of Plants (UPOV) highly recommends the use of molecular markers such as microsatellites to verify new varieties (UPOV, www.upov.int). Microsatellite markers have been widely used for various molecular genetic analyses, such as genetic diversity and population structure studies (Kim et al, 2016;Chung et al, 2019), construction of genetic linkage maps (Chang et al, 2018), identification of zygotic/ nucellar individuals (Woo et al, 2019), and cultivar/genotype identification (Kim et al, 2019).…”

More than 30 citrus varieties have been developed in Korea over almost four decades. Despite the economic importance of citrus fruit production, reliable technologies for the identification of citrus varieties bred in Korea have not been established. We developed 53 polymorphic nuclear microsatellite markers fully covering the nine pseudochromosomes of citrus and applied them to the discrimination of the 32 available citrus varieties bred in Korea. Most Korean citrus varieties were clearly discriminated by 245 alleles derived from the polymorphic microsatellite loci. However, nucellar or bud sport mutant varieties originated from Citrus hybrid 'Shiranuhi' could not be discriminated from each other because they share identical genotypes on all of the microsatellite loci investigated. The microsatellite markers developed in this study will be an efficient molecular genetic tool to protect breeders' rights and guarantee the quality of nursery plants in the citrus industry.
