Extract from Wikipedia article

Rapeseed (Brassica napus), also known as rape, oilseed rape, rapa, rappi, rapaseed (and, in the case of one particular group of cultivars, canola), is a bright-yellow flowering member of the family Brassicaceae (mustard or cabbage family), consumed in China (油菜: Mandarin Pinyin yóucài; Cantonese:yau choy) and Southern Africa as a vegetable. The name derives from the Latin for turnip, rāpa or rāpum, and is first recorded in English at the end of the 14th century. Older writers usually distinguished the turnip and rape by the adjectives 'round' and 'long' (-'rooted'), respectively. Rutabagas, Brassica napobrassica, are sometimes considered a variety of B. napus. Some botanists also include the closely related B. campestris within B. napus.[+]

AI-generated description

Brassica napus, also known as rapeseed or oilseed rape, is a bright-yellow flowering member of the family Brassicaceae. In Qatar, it has been found to be an introduced species, often growing as a weed in agricultural areas and along roadsides. Studies have reported its presence in various regions of Qatar, including the northern and southern parts of the country. The plant's adaptability to Qatar's arid climate and soil conditions has allowed it to naturalize and become a common sight in the country's flora.

AI-generated summary of observations

Rapeseed (Brassica napus) was observed growing on Green Circles with center-pivot irrigation in Irkhaya Farms, south-western Qatar. The plant was seen at various stages of growth, including blooming with yellow flowers in February 2015 and 2016, and producing siliqua fruits in February 2016. The leaves were observed to be glossy and form a rosette, with basal leaves present at the base of the plant. The rapeseed plants were found to be thriving in the irrigated fields, with masses of blooming plants visible in February 2016. Close-up observations revealed detailed views of the yellow flowers and fruits of the plant. Overall, the observations suggest that Brassica napus is a successful crop in Qatar's irrigated agricultural systems.
