Abstract

Coffee has caffeine content that may be beneficial for health in the appropriate dosage use. Robusta coffee has a higher caffeine content compared to other types of coffee. Robusta coffee is the most widely cultivated type of coffee in Indonesia as it is more tolerant of certain pests and is suitable for the climate in Indonesia. Supporting the germplasm diversity management, identification of robusta coffee diversity is essential, both in terms of phenotypic and genotypic characters. This research has been conducted as a comprehensive part of phenotyping identification of robusta coffee populations in Gunung Betung, Bogorejo, Pesawaran, Lampung. This investigation has aimed to determine the diversity of robusta coffee phenotypes according to leaf width on plagiotropic branches. Samples were taken using purposive sampling method on 30 individual robusta coffee plants. Identification has been done based on leaf morphology, width of the first leaf on the first plagiotropic branch. Leaf width can be utilised as an indicator to identify different robusta coffee varieties or genotypes. The phenotypic character of the width of the first leaf on the first plagiotrope branch is crucial because this branch is the first point where the crop shows an early response to its environment, which may include factors such as light, water, and nutrients. Leaf width has been measured directly in the field using a standardised measuring instrument on the widest part of the first leaf on the lowest plagiotrope branch. The results have demonstrated significant diversity, with a range of leaf widths varying from 6.0 cm to 15.0 cm with an average of 9.21 cm. This variation has indicated the existence of genetic diversity based on phenotypic characters among members of the robusta coffee population at Gunung Betung, Bogorejo, Pesawaran.
