Oryza Glaberrima has limited distribution and is mainly grown in West Africa.

In this article, we will delve deeper into the lesser-known

Oryza Glaberrima. Description of

Oryza Glaberrima and its subspecies

Oryza Glaberrima is an annual cereal grass cultivated in West Africa. It is believed to have been domesticated over 3,000 years ago in the Niger River Valley and, unlike Oryza Sativa, has never been cultivated outside Africa.

Oryza Glaberrima has two subspecies,

Oryza Glaberrima var. glaberrima and

Oryza Glaberrima var.

brevidens.

Oryza Glaberrima var.

glaberrima has a long panicle, while

Oryza Glaberrima var. brevidens has a reduced panicle.

Characteristics of

Oryza Glaberrima

Oryza Glaberrima is hardy and well-suited to the harsh West African climate. It is pest-resistant, which makes it easier to cultivate, and its high tillering capacity means it produces many heads per plant.

With its low labour requirements and relatively short growth cycle,

Oryza Glaberrima is a convenient crop to cultivate, especially in West Africa. Additionally, it has a distinctive nutty flavor, making it an attractive option to consumers who enjoy unique tastes.

Similarities Between Oryza Sativa and

Oryza Glaberrima

Despite their differences, Oryza Sativa and

Oryza Glaberrima share some similarities. Below, we will explore the commonalities between these two cereal grasses.

Family, genus, and chromosome count in common

Oryza Sativa and

Oryza Glaberrima belong to the same family, Poaceae or Gramineae, as other cereal crops like maize, wheat, and barley. They also share the same genus, Oryza.

Both species have diploid genomes, meaning they have 12 chromosomes.

Domestication and subspecies formation

Both Oryza Sativa and

Oryza Glaberrima were domesticated by humans. Oryza Sativa in Asia and

Oryza Glaberrima in West Africa.

Domestication led to the formation of different subspecies that we see today. Oryza Sativa has two main subspecies, Indica and Japonica, while

Oryza Glaberrima has two subspecies, var.

glaberrima and var. brevidens.

These subspecies differ primarily in their physical characteristics, such as the shape of panicle, grain size, and growth habits.

Conclusion

Overall,

Oryza Glaberrima has unique characteristics like its hardiness, pest resistance and nutty flavor, making it a desirable crop in West Africa. Although both Oryza Sativa and

Oryza Glaberrima share some similarities, they are still distinctive in their physical features, subspecies, distribution, and global production.
