Breeding New Premium Quality Cultivars by Citrus Breeding 2.0 in Japan: An Integrative Approach Suggested by Genealogy

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 conventional breeding, even the application of marker-assisted selection technique. Conventional breeding cannot achieve simultaneously it has been regarded as a trilemma. Integrating genomics-assisted (GAB) approach relies on quantitative trait locus detection by genome-wide association study prediction genomic using enriched marker genotypes enhances efficiency contributes to eliminating Besides efforts, analysis genealogy indigenous revealed many high-quality were selected within few generations. It suggested selecting new premium quality hybrid is possible integrating GAB technique helps avoid This review describes how approach, “Citrus Breeding 2.0” works for rapidly developing new, hybrids introduces applications this technique, specifically, rebreeding, complementary mimic based ongoing program NARO, Japan.
