What is a Canola Plant?

Let’s start by exploring what exactly a canola plant is, and learn how it’s cultivated from seed to harvest in various parts of the world.

Defining Canola and its Origins

Canola has its roots in rapeseed, which originated in the Himalayan foothills over 2,000 years ago. The plant was initially cultivated for its oil-rich seeds, but it was also known to contain a toxic compound called erucic acid, which made it unsuitable for human consumption. In the early 20th century, Canadian scientists began experimenting with rapeseed to breed a variety that was low in erucic acid and high in edible oil.

This breeding process led to the development of canola, short for “Canadian Oil, Low Acid.” Canola is now grown globally, primarily for its nutritious oil, which is used in cooking and as a biofuel. The name change from rapeseed to canola was made to emphasize the plant’s new purpose: producing edible oil.

Interestingly, canola has a very low erucic acid content compared to traditional rapeseed, making it safe for human consumption. In fact, many countries require canola seeds to contain less than 2% erucic acid to be considered “canola.” Today, canola is one of the world’s leading oilseed crops, with millions of tons harvested annually.

Key Characteristics of Canola Plants

Canola plants are easy to recognize due to their unique physical characteristics. When it comes to growth habits, canola plants tend to grow quite tall, often reaching heights of up to 3 feet (90 cm). They have a branching habit, with stems that split into smaller branches as they mature. This branching habit allows the plant to produce more flowers and seeds.

One distinctive feature of canola plants is their flower color. These flowers are typically yellow in color, with four petals arranged in a cross-like pattern. The flowers bloom in clusters at the end of each branch, creating a vibrant display of color in fields where they’re grown. In terms of seed size, canola seeds are small and brown or black in color.

When it comes to identifying canola plants, look for their distinctive yellow flowers and tall growth habit. Keep in mind that other plants may also produce similar-looking flowers, so be sure to check the plant’s leaves and stems to confirm its identity. With their unique characteristics, canola plants are an interesting subject to study and observe.

History of Canola Production

Canola production has a fascinating history that spans decades, from its humble beginnings as a Canadian innovation to its global popularity today. Let’s take a closer look at how it all started.

Rapeseed, the precursor to modern canola, has its roots in ancient Europe and Asia. The earliest recorded cultivation of rapeseed dates back to 14th-century China, where it was grown for both food and oil production. In medieval Europe, rapeseed was primarily used as a condiment and for medicinal purposes. However, the plant’s strong flavor and potential toxicity made it less desirable for human consumption.

In contrast, Asian cultures revered rapeseed for its culinary value, using it in dishes such as stir-fries and braises. The oil extracted from rapeseed seeds was also prized for its high smoke point and flavor profile. As trade routes expanded, rapeseed cultivation spread throughout Europe, where it became a staple crop in many regions.

The introduction of rapeseed to North America began in the late 19th century, when Canadian farmers started cultivating the plant for oil production. To improve the crop’s quality and reduce its toxic compounds, scientists crossed rapeseed with other plants, ultimately giving rise to modern canola. Today, canola is grown globally for both food and industrial applications, including the production of biodiesel and animal feed.

The Development of Modern Canola

The development of modern canola varieties is a remarkable story that showcases the power of plant breeding. In the 1960s and 1970s, Canadian scientists began experimenting with rapeseed, a crop native to Asia, to create a new species with improved traits. The goal was to produce a oilseed that was not only higher in oil content but also lower in erucic acid, a compound found in traditional rapeseed that was linked to health concerns.

Through rigorous breeding efforts, researchers at the University of Manitoba and Agriculture Canada developed the first modern canola varieties. These early versions boasted increased oil yields, better disease resistance, and improved nutritional profiles. The breakthrough came with the introduction of low-erucic-acid rapeseed (LEAR), which reduced the erucic acid content by 90%. This innovation paved the way for widespread adoption across Canada and eventually around the world.

Today, modern canola varieties have become the standard in many countries due to their superior performance. Farmers appreciate the improved yields, easier cultivation, and enhanced disease resistance that these new varieties offer. As a result, canola has emerged as one of the top oilseed crops globally, with over 40 million acres cultivated worldwide.
