Varieties:

• Amara (ID: 113)

Introduction

Brassica carinata, commonly known as Ethiopian mustard or Abyssinian cabbage, is a member of the Brassicaceae family. It is an amphidiploid species, derived from an ancient cross between Brassica nigra and Brassica oleracea. This plant is significant for its oilseed properties and its potential as a biofuel source. Brassica carinata is also used as a leaf vegetable, particularly in Ethiopia, where it is known for its mild flavor.

Characteristics

• Physical Characteristics: Brassica carinata is an annual herb that grows erect, typically reaching heights of 1 to 6 feet (0.3 to 1.8 meters), with highly branched stems and a well-developed taproot system. The leaves are arranged alternately on the stems, and the plant produces small, yellow to brown seeds.
• Growing Conditions: It thrives in cool to temperate climates with adequate moisture, tolerating a wide range of temperatures (5-35°C) and rainfall (800-1,700 mm). The plant prefers well-drained, fertile soil with a pH between 5.5 and 8.5.
• Lifecycle: The lifecycle of Brassica carinata can vary depending on the cultivar and environmental conditions. In temperate regions, it can complete its lifecycle in about 180 days, with flowering occurring approximately 10 weeks after germination for oil types and 12 weeks for vegetable types.

Why is this crop useful for space?

Brassica carinata could be beneficial for space cultivation due to several reasons: - Drought Tolerance: Its ability to tolerate drought and heat makes it suitable for controlled environments with limited water resources. - Nutritional Value: As a leaf vegetable, it provides essential nutrients, which could be crucial in long-duration space missions. - Biofuel Potential: The high erucic acid content in its oil makes it a promising source for biofuels, which could be used in space missions for energy needs. - Self-Pollination: Unlike many Brassica species, B. carinata can efficiently self-pollinate, reducing reliance on external pollinators in space environments.

History of Cultivation in Space (if there is any)

There is no documented history of Brassica carinata being cultivated in space. However, its characteristics make it a candidate for future space agriculture projects focused on sustainable food and biofuel production. Controlled environment agriculture (CEA) systems, which are being developed for space missions, could potentially support the growth of Brassica carinata due to its adaptability and nutritional value.
