HEY!!

✔Early farmers cultivated wild cabbage or Brassica oleracea. but due to artificial selection.

✔This wild cabbage developed into many varieties such as cabbage, broccoli, kohlrabi, cauliflower, kale, and brussels.

✔ These varieties were artificially selected because of their characteristic traits.

✔This is an example of artificial selection since humans have generated the different vegetables from cabbage by selectively breeding for specific characteristics.

✔Some farmers selected for very short distances between leaves, and have bred the cabbage we eat.

✔Some have wanted to select for arrested flower development, and have bred broccoli, or for sterile flowers, and have made the cauliflower.

✔Selecting swollen parts led to production of kohlrabi. Selecting the characteristic of slightly larger leaves led to producing a leafy vegetable called kale.

We can observe a great variation in plants. By the help of knowledge humans and by the passage of time, humans created totally different species.

For example, variants in wild cabbage are as follows.

(I) Short distances between leaves, led to the formation of green leaf buds, which is a common cabbage.

(II) Bred broccoli

(III) The variant with sterile flowers has made the cauliflower.

(IV) Kholrabi

(V) Kale
