Review on Genetic Diversity Analysis of Ethiopian Coffee Accessions Collected from Limmu Coffee Growing Areas

Coffee is the world’s most widely traded tropical agricultural commodity next to oil and is the backbone of the Ethiopian economy. It greatly contributes to the economy of Ethiopia. Limmu is one of the major coffee-producing woredas of Jimma Zone and coffee from this area is well known by the name of ‘Limmu Coffee’ and fetches very high prices on the world market for its peculiar winy flavor. Having known this fact, Jimma Agricultural Research Center collected 220 coffee accessions from this area to improve productivity and quality. Apart from collection, studies on different batches of Limmu coffee collection have also been conducted as information on genetic variability for morphological and organoleptic traits is a prerequisite for further improvement of the yield and quality of coffee. However, the results of the studies have not been summarized in a way to address the readers. Thus, the objective of this review paper is to summarize the findings of different studies conducted on the genetic diversity of Limmu coffee collections. The results of the studies showed that there is sufficient variability among the accessions for quantitative traits and cup quality traits to improve the yield and the quality of Limmu coffee. In conclusion, the observed variability for quantitative and cup quality attributes should be utilized to improve the productivity as well as the quality of coffee through selection and hybridization. However, as most of the diversity studies were conducted using conventional methods, the contemporary diversity analysis method should be employed to supplement the conventional method. Besides, the organoleptic quality analysis should also be supported with biochemical characterization.
