The Diversity of Green Bean Biochemical Compounds in Robusta Coffee (Coffea canephora Pierre ex A. Froehner) as Evaluated by Near Infrared Spectroscopy | Chapter 07 | Advances and Trends in Agricultural Sciences Vol. 3
Aims: This study characterized biochemical compound variability that influence green bean quality in C. canephora as a basis for identifying heterogeneous genotypes for use in crop improvement because genetic erosion aided by climate change effects is gradually threatening the cultivation of Ugandan Robusta coffee (Coffea canephora) local races. Study Design: Four hundred and fifty four accessions from twenty four districts were analyzed with Near Infra Red Spectroscopy (NIRS) for six biochemical compounds using calibrations developed at CIRAD, France. Place and Duration of Study: This work was conducted at the National Coffee Resources Research Institute (NaCORRI), Uganda between January 2007 and December 2013. Methodology: Spectrometer Nirsystem 6500 Foss- (Denmark) machine and Software ISI NIRS 2 version 4.11 (Infra Soft International, Port Matilda, USA) were used to analyze ground samples in diffuse reflectance from 400 nm to 2500 nm (2 nm steps) and predictive model...
