Research advances and prospects of spinach breeding, genetics, and genomics
Spinach (Spinacia oleracea) is a diploid (2n = 2x = 12), wind-pollinated and highly heterozygous crop. The plants are mostly dioecious, although some monoecious plants exist. Spinach is an economically important cool-season leafy vegetable crop. Demand for spinach is increasing worldwide, particular...

| description | Spinach (Spinacia oleracea) is a diploid (2n = 2x = 12), wind-pollinated and highly heterozygous crop. The plants are mostly dioecious, although some monoecious plants exist. Spinach is an economically important cool-season leafy vegetable crop. Demand for spinach is increasing worldwide, particularly due to its high nutritional content. Spinach is a versatile crop eaten raw or cooked and used as salads or mixed with other cuisines. This review article provides an overview of origin and domestication, genetic diversity and population structure, genetic and genomic resources, major diseases threatening spinach production, breeding progress, and synthesizing how these resources can help in spinach improvement. The rapid development of genomic and sequence resources of spinach has increased biological and genetics research and laid the foundation for adopting molecular breeding. Downy mildew is the most serious disease affecting spinach and breeding programs focus on developing cultivars resistant to continually emerging new races of downy mildew pathogens. The use of genomic and molecular resources and approaches offers promises in population improvement and hybrid development to address biotic and abiotic stresses production challenges and provide improved breeding materials and strategies against the rapidly changing pathogen races and climatic conditions. |
