Distinguishing biological characteristics of coffee plants
Distinguishing Biological Characteristics Of Coffee Plants: Coffee is a member of the Rubiaceae plant family, which includes 500 genera and over 6000 species. Most are tropical trees and plants planted in the jungle’s lower levels.The genus quinine, as well as other valuable chemicals, are members of the plant family. Nonetheless, in the Rubiaceae family, the genus Coffea has played the most important economic role. Let Helena learn about Distinguishing biological characteristics of coffee plants

Botanists have had many conflicts about constructing an accurate categorization system since Linnaeus accurately described The Genus Coffee in the mid-18th century. At least 25 critical species, native species, tropical Africa, and a few Indian Ocean islands, especially Madagascar, are found.

Due to the diversity of plants and seeds in the genus Coffee (Coffea), categorizing and recognizing a plant in the genus Coffee (Coffea) is becoming increasingly challenging. The leaves of all Coffee species are yellowish, dark blue, dark yellow, or tinged with purple and range in height from a bit of bush to trees over 10 meters tall.

Distinguishing biological characteristics of coffee plants

Coffea Arabica (tea coffee), which accounts for more than 60% of global production, and Coffea Canephora are the two most economically important coffee species (Robusta coffee). Coffea Liberica and Coffea Dewevrei are two other types farmed in lower quantities (Excelsa coffee

Coffee plants Arabica – Arabica coffee bean

In 1753, Linnaeus published the first description of arabica coffee. “Typica” and “Bourbon” are the most well-known varieties. Caturra (Brazil, Colombia), Mundo Novo (Brazil), Tico (Central America), San Ramon dwarf, and Jamaican Blue Mountain are just a few of the strains and types that have come from here.

The Arabica tree has dark blue oval-shaped leaves and a giant bud. The plant produces fruit-shaped fruit that matures in 7 to 9 months and typically contains two flat seeds (coffee beans), But it is termed Culi coffee when only one seed grows.

Disease resistance is a primary goal of plant breeding initiatives since Arabica coffee is susceptible to insect assaults and outbreaks. Latin America, Central and East Africa, India, and Indonesia are all home to Arabica coffee.

Coffea canephora – Robusta coffee

Robusta coffee bean is widely farmed cultivar of this plant. 
It can grow to be healthy bush or small tree up to 10 meters tall, although its root structure is shallow rather than deep. 
It takes up to 11 months for the fruit to mature. The seeds are round and smaller than the Arabica coffee fruit. Robusta coffee is grown in West and Central Africa, from Southeast Asia to Brazil’s Conillon region.

Liberica coffee (Coffea liberica)

Liberica coffee is huge, vigorous plant with stiff broad leaves that can grow up to 18 meters tall. 
Large berries with lot of seeds. Liberica coffee is grown in Malaysia and West Africa. However, a tiny quantity is exchanged due to its low taste standards.

Crop breeding

Arabica coffee

Arabica coffee tree is a tetrahedron and can pollinate itself. There are two different plant varieties, typical and bourbon. Historically, typical was grown in Latin America and Asia, while bourbon bean was produced in South America and East Africa through French fabric.

Because C. arabica is a self-pollinating plant, these varieties maintain genetic stability. However, the spontaneous mutation expresses desirable characteristics raised in its way and exploited for cross-breeding purposes. A few variations and combinations are described below:

Wide varieties are developed to deliver dark economic returns in regional conditions such as climate, land, farming methods, and the prevalence of pests and diseases. Better tree variety populations are known as:

  • Blue Moutain is grown in Jamaica and Kenya
  • Mundo Novo – a cross between typical and bourbon, commonly grown in Brazil
  • Kent – raised in India, may be resistant to some common diseases.
  • Casual – the result of the Mundo Novo and Caturra hybrids, which feature yellow leaves and red berries: Catuai-amarelo and Catuai-Vermelho

Coffea canephora

  1. canephora is dissingral, cannot be fertilized on its own, and has various forms and types. Identifying plant varieties is a bit difficult, but the two main types are recognized:

– ‘Robusta’ coffee bean – vertical form

– ‘Nganda’ – the spread of

Arabica / Robusta hybrid

Growth and flowering, yield, grain size and stickiness, quality, caffeine intake, disease resistance, and drought resilience are all carefully bred into the level of coffee quality.

She was crossing the Arabica coffee species Coffea with Robusta to improve Arabica’s disease resistance, robusta coffee leaf rust vitality, or Robusta’s quality.

Hybrid de Timor is a natural hybrid of Arabica and Robusta with 44 chromosomes resembling coffee arabica species. Catimor is a rust-resistant coffee bean hybrid between Caturra and Hibrido de Timor.

Ruiru Eleven is a low hybrid variety. In 1985, the Coffee Research Station in Ruiru, Kenya, launched the product. Ruiru 11 can induce coffee berry disease and rust. It’s also very productive and stable at planting densities twice as high as the average.
