“…This high percentage indicates that the clones were genetically similar to each other. In Lampung, coffee plants, including Robusta coffee, are introduced plants, which originated from Africa (Herrera and Lambot 2017). Around the year 1900, non-selected genetic materials of Robusta coffee were directly brought from Uganda and Democratic Republic of the Congo to Java and indirectly brought to Java through Europe, and then subjected to selection from 1900-1930 (Montagnon et al 1998).…”

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.

“…Both Coffea arabica and C. canephora are native to the African equatorial forest 72 . Coffea arabica , which is native to the Ethiopian tropical forests, can be cultivated between a range of 800–2000 m, and C. canephora , which is native to the lowland forests of the Congo river basin can be grown between <500–1500 m 42,72 . Optimal rainfall for C. arabica ranges between 1200–1800 mm, and temperatures between 18–21 °C 42 .…”

Floral traits and rewards are important in mediating interactions between plants and pollinators. Agricultural management practices can affect abiotic factors known to influence floral traits; however, our understanding of the links between agricultural practices and floral trait expression is still poorly understood. Variation in floral morphological, nectar, and pollen traits of two important agricultural species, Coffea arabica and C. canephora , was assessed under different agricultural practices (sun and shade). Corolla diameter and corolla tube length were larger and pollen total nitrogen content greater in shade plantations of C. canephora than sun plantations. Corolla tube length and anther filament length were larger in shade plantations of C. arabica . No effect of agricultural practice was found on nectar volume, sugar or caffeine concentrations, or pollen production. Pollen total nitrogen content was lower in sun than shade plantations of C. canephora , but no difference was found between sun and shade for C. arabica . This study provides baseline data on the influence of agronomic practices on C. arabica and C. canephora floral traits and also helps fill a gap in knowledge about the effects of shade trees on floral traits, which can be pertinent to other agroforestry systems.

“…Open questions remain regarding genotypic differences in temperature tolerance and response to elevated [CO2]. Furthermore, hybrid varieties between Arabica, Robusta and hybrids of Timor have been developed mainly for pest and/or disease resistance (Bertrand et al 2016;Herrera & Lambot 2017) that could potentially also benefit of Robusta's tolerance to higher temperature. To analyze this, data of different varieties on the physiological (particularly stomatal conductance) and morphological characteristics are required.…”
