Abstract

Arabica coffee genotypes having larger beans weight usually cost higher in prices than smaller ones. Bean length, breadth and thickness are the three components which determine beans weight. Performance of thirty different Arabica coffee genotypes, which were approved to be top yielder during the earlier preliminary evaluation, were evaluated for these components at four different locations in south-western Ethiopia. The objective of the study was to evaluate the effect of environmental conditions on size and shape of arabica coffee beans. The trials were laid down in randomized complete block design using three replications. The analyses of variance revealed that differences among genotypes for bean length, breadth and thickness at all locations were highly significant (P<0.01). Genotypes exhibited higher mean values for beans length and thickness proportional to the amount of rainfall received at the different locations during the period of beans growth, edaphic factors not limiting. Irrespective of the interaction, six genotypes: 8219, 7803A, 7809B, 8211, 8213 and 8143 exhibited higher mean values for beans length that ranged from 0.951 to 1.031 cm in ascending order. Genotypes exhibited a balanced dimension for beans length and breadth in medium than higher altitude areas. The study illustrated that size and shape of coffee beans are highly dependent on environmental conditions in addition to genotype. The identification of coffee type showing high yield potential, fine flavor and desirable bean sizes indicates that it is possible to improve Arabica coffee genotypes for multiple characters simultaneously.

Keywords: Beans Breadth, Beans Thickness, Beans Length, Locations, Genotypes.
