Coffea arabica L. is a native coffee species probably originated in Abyssinia, now Ethiopia. The genetic diversity of C. arabica has economic implications directly related to profits by breeding for developing new varieties to a global market. The economic value of C. arabica genetic resources are estimated at US$ 420 million, considered a 10% discount rate. Understanding the extent of traits variability and genetic diversity is essential to guide crosses between genotypes, targeting the development of new varieties with high economic value. This chapter will present the C. arabica economic importance, primarily to Brazil, the most significant world producer; we will outline the origin and dispersion of arabica coffee and briefly show the leading germplasm banks. We will also point out contribution of genetic diversity studies based on morphological, agronomic traits, and molecular markers supporting the development of new varieties. Finally, we present an outline for the future.

“…Coffee belongs to the genus Coffea, sub-genus Coffea, family Rubiaceae and grows mostly in tropical and subtropical regions (Ferreiraa et al 2019). The Arabica coffee (C. arabica L.) and Robusta coffee (C. canephora Pierre ex A. Froehner) are the two most cultivated coffee species world-wide which account for 60% and 40% of total world coffee production, respectively (Davis et al 2019).…”

Genetic diversity among 24 clones of robusta coffee in Lampung based on RAPD markers

Abstract. Ramadiana S, Hapsoro D, Evizal R, Setiawan K, Karyanto A, Yusnita. 2021. Genetic diversity among 24 clones of robusta coffee in Lampung based on RAPD markers. Biodiversitas 22: 3122-3129. This study aimed to estimate the genetic diversity among 24 clones of Robusta coffee from Lampung, Indonesia, by use of RAPD markers. The clones consisted of 18 local and 6 BP clones. These BP clones were developed from a breeding program of The Indonesian Coffee and Cocoa Research Institute. Genomic DNAs extracted from these clones were subjected to polymerase chain reaction and the amplified products were run using gel electrophoresis. Eleven random primers produced clear, reproducible, scorable bands. Fifty-four of 86 bands showed polymorphism and were used to construct a dendrogram based on UPGMA Jaccard's Similarity Coefficients. The genetic base of the population was narrow (average genetic similarity 68.4%), ranging from 26-93%. The genetic similarity of the local clones was higher than that of BP clones. The clones were clustered into five groups. Group 1 contained one clone (BP 534), while each of Group II-V contained more than one clone. The average genetic similarity of BP 534 to each clone of Group II-V was 41%. The genetic similarity of clones in Group II, III, IV, and V were 55.5%, 43.0%, 81.1%, and 80.1%, respectively. This research should be very useful for selecting parents in a breeding program to produce better clones of Robusta coffee.

“…Coffee ( Coffea sp.) is the most representative plant of the family Rubiaceae, presenting different species such as Coffea arabica L. and Coffea canephora Pierre, which are the most well‐known species of the genus 1 . Coffee production is highly relevant socially and economically and, considering both main varieties grown in the country, Brazil produced 3 Gkg in 2019 – the highest production and exportation volume in the world 2 .…”

“…Considering the pollination ecosystem services, it is important to highlight that most crops are ephemeral, especially coffee (flowering), offering superabundant resources during very short time frames 1 . This dynamic of production systems forces pollinators, especially those with life cycles that last longer than the flowering of crops (most pollinator species), to forage for other food sources 15,16 .…”

Does a coffee plantation host potential pollinators when it is not flowering? Bee distribution in an agricultural landscape with high biological diversity in the BrazilianCampo Rupestre

BACKGROUND Natural environments within agricultural landscapes have been recognized as reservoirs of biodiversity and, therefore, providers of fundamental ecosystem services to human beings. Bees are the main providers of pollination and thus contribute to the production of food consumed worldwide. In this work, we evaluated the distribution of bees in an agricultural landscape of coffee plantation before and after coffee flowering. We aimed at understanding how richness, abundance and composition of bee communities vary among the different vegetation types within and around the coffee crops. RESULTS A total of 638 bees were collected – 312 in the dry season and 326 in the rainy season – totaling 85 species. The sampling methods collected different species, which provided complementary sampling. Only Euglossa leucotricha and Eulaema nigrita were recurrent in both seasons and vegetation types. There was no temporal difference in richness or abundance; however, both varied in relation to the vegetation type and were higher in the coffee‐native transition area. Diverging from richness or abundance, the composition of the communities differed regarding season and vegetation types. CONCLUSION We reinforce the importance of maintaining native vegetation in areas surrounding coffee plantations since the crop poorly hosts pollinators when it is not flowering. Natural and semi‐natural areas may act as reservoirs of floral visitors, thus maintaining potential cross‐pollination services available to coffee production. © 2020 Society of Chemical Industry
