“…About 70% of the mutant varieties have been developed using physical mutagens [18]. In fruit crops, physical mutagens have altered key horticultural traits like seedlessness, precocious bearing, and dwarfism [19][20][21]. Other traits include fruit ripening time, fruit skin and flesh color, fruit aroma, self-compatibility, pathogen resistance, and fertility restoration in sterile hybrids.…”

“…Now there are several commercial seedless varieties including Daisy SL, Kinnow SL, Fairchild SL, and Tango that have been developed from their seedy parents through mutation breeding and are being commercially cultivated [29]. Other commercial mutants in citrus include sweet orange varieties Jin Cheng [30], Kozan [21], and NIAB Kinnow mandarin [31]. In grapefruit, Rio Red and Star Ruby are two induced mutants that have obtained commercial significance due to their better fruit color and seedlessness, respectively [32].…”

Citrus is a valuable fruit crop worldwide. It not only provides essential minerals and vitamins but is also of great commercial importance. Conventional research has contributed a lot to the improvement of this fruit plant. Numerous improved varieties have been developed through conventional breeding, mutational breeding, polyploidization and tissue culture yet pathogens continue to emerge at a consistent pace over a wide range of citrus species. Citriculture is vulnerable to various biotic and abiotic stresses which are quite difficult to be controlled through conventional research. Biotechnological intervention including transgenesis, genome editing, and OMICS offers several innovative options to resolve existing issues in this fruit crop. Genetic transformation has been established in many citrus species and transgenic plants have been developed having the ability to tolerate bacterial, viral, and fungal pathogens. Genome editing has also been worked out to develop disease-resistant plants. Likewise, advancement in OMICS has helped to improve citrus fruit through the knowledge of genomics, transcriptomics, proteomics, metabolomics, interactomics, and phenomics. This chapter highlights not only the milestones achieved through conventional research but also briefs about the achievements attained through advanced molecular biology research.

Mandarins are mostly preferred specie of Citrus genus, and there has been a continuous rise in consumption and global marketing due to having easy-to-peel, attractive flavor, and fresh consumption advantages. However, most of the existing knowledge on quality traits of citrus fruit comes from research conducted on oranges, which are the main products for the citrus juice manufacturing industry. In recent years, mandarin production in Turkey surpassed orange production and took the first place in citrus production. Mandarins are mostly grown in the Mediterranean and Aegean Regions of Turkey. Due to suitable climatic conditions, they are also grown in the microclimatic condition in Rize province located in the Eastern Black Sea region. In this study, we reported the total phenolic content, total antioxidant capacity, and volatiles of 12 Satsuma mandarin genotypes selected from Rize province of Turkey. Considerable differences in the total phenolic content, total antioxidant capacity (2,2-diphenyl-1-picrylhydrazyl assay), and fruit volatile constituent were found among the 12 selected Satsuma mandarin genotypes. The total phenolic content ranged from 3.50 to 22.53 mg of gallic acid equivalent per 100 g of the fruit sample in the selected mandarin genotypes. The total antioxidant capacity was the highest in genotype HA2 as 60.40%, and followed by IB (59.15%) and TEK3 (58.36%), respectively. A total of 30 aroma volatiles were detected from the juice samples of 12 mandarin genotypes by GC/MS, which comprised six alcohols, three aldehydes (including one monoterpene), three esters, one ketone, and one other volatiles. The main volatile compounds were identified in fruits of all Satsuma mandarin genotypes as α-terpineol (0.6–1.88%), linalool (1.1–3.21%), γ-terpinene (4.41–5.5%), β-myrcene (0.9–1.6%), dl-limonene (79.71–85.12%), α-farnesene (1.1–2.44), and d-germacrene (0.66–1.37%). Limonene accounts for most of the aroma compounds (79.71–85.12%) in fruits of all Satsuma genotypes. The genotypes MP and TEK8 had the highest total phenolic content, and HA2, IB, and TEK 3 had the highest antioxidant capacity. The YU2 genotype was found to contain more aroma compounds than the other genotypes. The genotypes selected on the basis of their high bioactive content could be used to develop new Satsuma mandarin cultivars with high human health promoting contents.

“…However, the demand has increased for high-quality new cultivars easy-to-peel and which meet consumers' needs in a short period [3]. Tremendous efforts have been devoted to mutation breeding in citrus to select a cultivar from sport, nucellar seedling [4][5][6][7], or after irradiation [8]. Though mutation breeding has successfully selected spontaneous or induced mutants in various varieties based on color break, rind or flesh color, fruit shape, acidity, or sugar content, mutation occurs at a low frequency [9], and the mutation spectrum depends on the varieties used for the method [3,[5][6][7].…”

Developing varieties with diverse features that satisfy varied commercial needs, improving overall fruit quality, and quickly releasing them, are prerequisites in citrus breeding. However, these three goals require trade-offs in conventional breeding, even with the application of the marker-assisted selection technique. Conventional breeding cannot achieve these three goals simultaneously and it has been regarded as a breeding trilemma. Integrating a genomics-assisted breeding (GAB) approach that relies on quantitative trait locus detection by genome-wide association study and genome-wide prediction of a trait by genomic selection using enriched marker genotypes enhances breeding efficiency and contributes to eliminating the trilemma. Besides these efforts, the analysis of the genealogy of indigenous citrus varieties revealed that many high-quality indigenous varieties were selected within a few generations. It suggested that selecting a new premium quality hybrid is possible by integrating it with the GAB technique and helps avoid the trilemma. This review describes how a new approach, “Citrus Breeding 2.0” works for rapidly developing new, premium quality hybrids and introduces three applications of this technique, specifically, rebreeding, complementary breeding, and mimic breeding based on the ongoing citrus breeding program in NARO, Japan.
