The researchers studied different types of garlic to see which ones were the best for growing big bulbs. They found that some types of garlic, like NDG-9 and NDG-41, were really good at producing big bulbs. They also discovered that traits like the number of cloves in a bulb and the size of the leaves were inherited from the parent plants and could help increase bulb yield. By selecting garlic with these traits, farmers can grow more garlic. The researchers also found that some clusters of garlic were very different from each other genetically, which means there is a lot of potential for improving garlic in the future.
