An herbaceous biennial plant in the Amaryllidaceae family called an onion (Allium cepa) is farmed for its edible bulb. Although it is now grown all over the world, primarily in temperate regions, the onion is most likely a native of southwestern Asia.
Red onion: Is it an Allium?
To suit the needs of the local people, a large amount of the vegetables, including onions, are imported into Kuwait from various nations. In Kuwaiti home cooking, onions are frequently used and play a significant role in the local cuisine. The population of Kuwait imports onions from a variety of nations, including Egypt, India, the Kingdom of Saudi Arabia, Iran, the United States, Australia, and New Zealand. The physical-chemical and antioxidant qualities of onion cultivars sold in the State of Kuwait are not known. Given the importance of onions in Kuwaiti cuisine, any scientific data on their physico-chemical and antioxidant characteristics will be helpful to customers in choosing the best yellow, white, and red onion cultivars to improve their health.
How about spring onions?
Allium fistulosum L., often known as spring onions, Welsh onions, and Japanese bunching onions, is a member of the genus Allium, family Liliaceae, and subgenus Cepa. Spring onion cultivation began in China about 200 BC and extended to Japan by 500 AD. It then moved to Southeast Asia. Although spring onions are produced all over the world, the majority of them are still grown in East Asia, specifically in Siberia and tropical Asia, where they are grown in China, Taiwan, Japan, the Philippines, Malaysia, and Indonesia. The perennial plant, which has hollow leaves and doesn’t produce bulbs, has long been used in Chinese folk medicine to cure conditions like the common cold, influenza, abdominal pain, headaches, and cardiovascular disease. It also has antifungal and antibacterial properties. In addition to being a delicious and aromatic vegetable, spring onions are also a good source of the vitamins C, A, and B6, thiamine, folate, rhamnose, galactose, glucose, arabinose, and xylose. One of the key objectives in crop breeding is the production of F1 hybrids. Since it takes eight or more generations of inbreeding to develop homozygous lines that may be used to produce hybrids, time is the fundamental constraint on breeding efforts. The use of doubled haploid (DH) lines in hybrid cultivars can improve this process. In this chapter, we provide a general overview of the origin, botanical classification, distribution, claimed health benefits, genetic resource and conservation, crop cultivation practices, recent advancements in biotechnology, and molecular biology, as well as their application for crop improvement in relation to conventional breeding techniques for spring onions. In this regard, somatic hybridization and mutational breeding are two promising methods for creating novel, highly productive and disease-resistant cultivars.
