Abstract

Development of specialty coffee product needs to be done by producing a product that has a good flavor, unique, and different from the axisting specialty coffee products. One of the varieties of Arabica coffee that has good potential to be developed into a specialty coffee is Maragogype coffee. This paper discusses the results of selection and characterization of physical and flavor quality of Arabica coffee varieties Maragogype in East Java. Selection was done in PTPN XII at Pancur/Angkrek and Kayumas Estate. It was obtained two superior genotypes those have high productivity and good taste, they are MP3 and MP4 with of productivity of 7,985.3 and 5,985.3 g cherries/tree, respectively. Maragogipe varieties showed good physical quality, in which 99% of bean belong to the large been category, whiches the highest of 1,000 beens, and good bulk density and apparent swelling. MP3 genotype had a floral, citrus acidity, mild, and very good sweetness characteristics. MP mix had the showed same characteristics, but its intensity was not as high as MP3. MP4 has herbal and flora characteristics with bitter after taste.Key words : Coffea arabica, maragogype, specialty coffee, characterization, selection, flavor, variety.

Abstract

One of the major diseases which limiting production in arabica coffee is the leaf rust caused by the fungus Hemileia vastatrix, B et Br. Selection and testing on thirteen promising arabica coffee clones were carried out at endemic area for leaf rust disease, Andungsari Research Station, for six fruiting times. The aims of these test were to find out superior planting material as clone with genetic resistance to leaf rust. As the beverage commodities, criterium selections for superiority clone besides resistant to leaf rust and yielding ability of more than 1,5 ton/ha also must be excellent in cup quality. Under this consideration, BP 416 A clone showed as the best high yielding ability i.e. 1,595 kg/ha and stable, besides resistant to leaf rust disease compared to the other clones tested. This clone had good cup quality, better than earlier released variety such as USDA 762 and S 795 although was not better than Andungsari 1 that were planted in the same location. The best physical bean characteristics was obtained on BP 513 A clone wich is derived from S 795 x Caturra red, having 89.2% of normal bean and 18.3% outurn characteristics. However, due to lower yielding and more susceptible to leaf rust, this clone could not be classified as superior clone.
