Garlic (Allium sativum) is a perennial bulbous plant which has been produced worldwide for many years. You will thus find various kinds and varieties among which it is sometimes difficult to find the appropriate one. Each type is indeed very specific to a growing area. The only way to have a successful crop (i.e yield - good multiplication rate - and quality) is to locally test potentially interesting varieties. Since ICS's first days, trials have been conducted with seeds from Mexico, China, France etc. French white varieties such as:
have given outstanding results in Saudi Arabia (under pivot irrigation). Genetic material from France has indeed proven it's quality by being widely used around the world for breeding purposes.
Apart from selecting adapted varieties, it is essential to consider seed quality as well. Garlic is a non-seedling plant whose propagation is exclusively vegetative. The cloves can carry many diseases (fungi, nematodes etc.) which can not only damage the plant but render the soil unusable for further production of garlic and related crops. Many publications insist on never growing onion or garlic crops following garlic to at least reduce long term risks.
