Before the 1960s, the main banana variety grown in the world was called "Big Mike", and the English name was Big Mike.

Because of its lack of seeds, thick skin and attractive appearance, it is loved by consumers and banana growers. At that time, most of the world's banana orchards were filled with this variety of bananas called "Big Mac".

However, the good times did not last long, and in 1950 a fungal disease called Fusarium blight swept through the banana plantations of Central America like a virus. Since all "Big Mack" banana plants are the product of asexual reproduction, the genes and disease resistance are the same, and there is no resistance to Fusarium blight.

Withered banana trees

Around 1960, large amounts of farmland were abandoned, and the companies that planted "Big Mack" were nearly bankrupt until they began to switch to sprout bananas. In 1965 the last "Big Mac" shipped to the United States was sold. Fusarium wilt wiped out large areas of Big Mac plantations in Central America, and only a small percentage of Big Mac banana trees are still alive in Thailand.

In the case of this inevitable extinction of varieties, the "banana hunters" looked for alternatives to various large mac bananas, and finally selected a variety that could resist fusarium wilting in 1947, and it was also the best banana under the big mac, which is the banana "Hua banana" that we eat now, but now this banana does not grow as big as the big mac, eats without the big mac, and has a weaker ability to resist transportation than the big mac.

Although the big mac has disappeared for nearly 60 years, we can still taste the taste of the big mac banana, the banana flavored fudge in the supermarket, everyone always says that the flavor is added too much, the taste is too strong, and the banana taste we usually eat is not the same, in fact, it is not, the taste of banana flavor fudge is the taste of the big mac banana, in the early 19th century, human beings invented synthetic flavor, at this time, many companies made a fruit flavor, Among them, the banana flavor perfectly restored the taste of the big mac banana and has been used to this day.

Now efforts are being made to genetically modify to create "big mac" bananas that are resistant to Fusarium wilt, trying to make this sweet banana reappear on our table.
