“…One of the largest Arabica coffee producing regions in Indonesia is North Sumatra which has 63.34 thousands ha of coffee plantations located at an altitude of 800-1,600 m above sea level (asl) with a production of 53.24 thousand tons of Arabica coffee beans (Direktorat Jenderal Perkebunan, 2017). Arabica coffee genotypes found in North Sumatra, in particular, are known to have wide genetic variability such as having genotype variations in resistance to coffee berry borer and taste attributes (Malau, 2019;Malau, Siagian, Sirait, Ambarita, et al, 2018;Malau, Sihotang, & Simanjuntak, 2019), different agronomic performance , different ability in seed germination (Malau, Siagian, Sirait, & Ambarita, 2018a), different levels of water stress tolerance (Malau, Siagian, Sirait, & Ambarita, 2018b), and different performance in organoleptic quality (Malau, Siagian, Sirait, & Pandiangan, 2017).…”

Coffee leaf rust disease (Hemileia vastatrix) causes large damage to Arabica coffee plantation in Asia, Africa, and America. In Indonesia, particularly in North Sumatra, the resistance level of Arabica coffee genotypes is still unknown. The objective of this research was to determine the resistance variability of Arabica coffee genotypes to leaf rust disease and its relation to leaf morphology. A total of 84 genotypes grown in North Sumatra were selected in November 2015 and 2016, and December 2017 using a nested design. Data were analyzed using nested design, correlation, stepwise regression, and cluster hierarchy analysis. The result showed that the G56 genotype performed the most resistant to leaf rust disease, with a severity of 5.21%. The severity of leaf rust disease has high genotypic variation, low heritability, and high genetic advance. Leaf morphological ratios showed moderate to high genotypic variation and heritability. The severity of leaf rust (y) significantly correlated with the ratio of leaf length to leaf area (x1) and the ratio of leaf length to leaf width (x2) with the equation y = 2.04 + 62.48x1 - 3.95x2, and multiple correlation coefficients R = 0.470 **. By using the leaf rust severity and the two ratios in the cluster analysis, these 84 genotypes were grouped into five clusters. The result showed that several Arabica coffee genotypes with a high level of resistance to leaf rust disease are potential to be further developed.

“…En otro estudio se determinó que la emergencia de plántulas vario entre 83.67 y 95% (Nasiro et al 2017). En la investigación de Malau et al (2018), afirmaron que los genotipos influyen en la capacidad de germinación de las semillas de café.…”

El objetivo de la presente investigación fue evaluar la emergencia, el vigor y fenología pre-trasplante de plántulas procedentes de semilla sembrada con y sin endocarpio, de nueve genotipos de café en Oxapampa, a fin de contar con nuevos genotipos de plántulas uniformes. Se utilizó un diseño experimental de bloque completo randomizado con arreglo factorial. En germinador cada unidad experimental fue conformada por dos surcos con 25 semillas en cada surco. En almacigo cada unidad experimental consto de 16 macetas: se muestrearon 4 macetas. Para las variables evaluadas en germinador y almacigo, los genotipos que destacaron, fueron los siguientes: UNACAF-89 (caturra rojo): porcentaje de emergencia (57 %); ritmo de crecimiento (4.04 mm/semana); UNACAF-116 (catimor): peso fresco de plántula (0.64 g); índice de vigor de plántula (53.79); peso fresco parte aérea (2.36 g); peso fresco de raíz (1.27 g); peso seco parte aérea (0.53 g); peso seco de raíz (0.16 g); volumen de raíz (1.25 ml); UNACAF-250 (obata): peso seco de plántula (0.13 g); altura de planta (10.13 cm); UNACAF-188 (caturra amarillo): tasa de emergencia (1.17 plantas/día) y UNACAF-213 (geisha): diámetro de tallo (2.81 mm). En el grupo de semillas sembradas sin endocarpio se presentaron mejoras para las variables: porcentaje de emergencia, tasa de emergencia, índice de vigor de plántula, peso fresco de raíz y en el volumen de raíz. UNACAF-89 (caturra rojo) obtuvo el mayor número de plantas en los estadios secundarios 09 y 10; asimismo, el mayor número de hipocótilos en el estadio secundario 07 de la escala BBCH.

“…The cultivation practices influence the components of dry fragrance, the aroma before and after drinking of coffee, viscosity level, sweetness, positive taste, coffee flavor combination, and consistency of coffee in several cups. Malau et al (2018) said that Arabica coffee genotypes affected seed germination ability. Seed germination ability was more affected by elevation of seed producing location rather than by precipitation and temperature…”

The quality of arabica coffee taste is determined by varieties, altitude, land cultivation, fermentation, drying, roasted, brewed, and potassium content in the seeds. This study aims to find out the Arabica coffee taste in Gayo Lues district planted on different characteristics of land morphology. The plant sampling was collected and determined by altitude places, different slope, similar varieties, similar age, and similar land cultivation. The total sample was observed from 3-5 plants of Arabica Coffea L. seeds in every unit observation. Parameter of observation was Arabica coffee taste in each altitude places. Variables of Arabica coffee taste that observed were aroma, flavor, after taste, acidity, body, balance, uniformity, clean cup, sweetness, overall, defect, and total score. One of the variables of determinant taste was altitudes place. The best taste was obtained from observation land unit (LU) 21 in scoring 83,75. The research results indicated that there was a positive relationship between altitude place and potassium content to Arabica coffee taste.
