There are three main types of oilseed rape, cabbage-type rape, mustard-type rape and kale-type rape.

1, cabbage-type rapeseed

The rapeseed plant is relatively short, and the growth of seedlings is fast, the root is more, the cumulus is elliptic-ovate or oblong, and there are prickly hairs or prickly hairs are relatively few, the size of the petals are not uniform, and the petals are overlapping each other on both sides of the growth of the stone is very low, the cabbage-type rapeseed seeds are brown or yellow, not necessarily equal in size, and the seeds are brown or yellow. The seeds of cabbage type rape are brown or yellow and not necessarily equal in size.

2, mustard-type rapeseed

native to the west or northwest of China, the plant is relatively high and not tightly arranged, relatively loose, divided into parts of the high and the main root is developed, but the oil content of the rapeseed is relatively low, generally in thirty to fifty percent, the quality of his oil is also relatively poor, the quality of the low, the growth cycle is relatively short, because of its low yield.

3, kale-type oilseed rape

From Europe and Japan, kale-type oilseed rape plant is tall, the root system is more developed, the stem and leaves were oval, because the color of its leaves and kale is very similar, so it is known as the kale-type oilseed rape, the seeds for the black or black-brown, the seed is relatively large and full, about three to four grams of the oilseed rape, the oil content of the oilseed rape is relatively high, generally in about 40 percent.

Growing environment of rapeseed:

Winter European rapeseed, which was formed 7,000 years ago, is suitable for growing in low-temperature areas; spring European rapeseed, which was born more than 400 years ago, has the shortest growing cycle.

Semi-winter European canola, which is suitable for a wider area of cultivation, was born in China more than 70 years ago, and after many generations of reproduction, European canola has been hybridized to adapt to different growing conditions and has different characteristics of many varieties.
