“…Color intensity was further assessed (under more uniform and appropriate light conditions) in the lab, and only 846 samples were selected for analysis with NIR (FOSS 6500, monochromator with autocup sampling module). Wavelength range was 400 to 2500 nm (Sánchez et al, 2014).…”

“…All samples were processed by NIR as described below. Calibrations for carotenoids predictions were described by Sánchez et al (2014). For the first batch of roots brought to the laboratory in the morning (up to 40 genotypes), NIR data was immediately analyzed to select the six samples with maximum predicted values of TBC.…”

“…However, they tend to overestimate carotenoid content when compared to HPLC due to other compounds also detected [21,22]. Near-infrared spectrometry (NIRS) has proven a costand time-efficient method for high-throughput screening for carotenoid content in sweet potato [23], banana [24,25], and cassava as well as for other important breeding traits such as dry matter content (DMC) and cyanogenic potential [26,27,28]. New portable devices such as iCheck and portable NIRS are being evaluated and show promise for use in the field when transport of fresh cassava roots to the nearest laboratory is a challenge [29].…”

“…Results of physic-chemical characterization of cassava germplasm were previously obtained and a significant difference among the chemical composition of different genotypes has been verified (Chávez et al, 2005;Padonou et al, 2005;Charoenkul et al, 2011;Silva et al, 2014;Sánchez et al, 2014).…”

Cassava (Manihot esculenta Crantz) is a plant from the Brazilian Amazonia which presents wide genetic variability. Since it is one of the most consumed foods in the world, efforts to generate more nutritive cultivars are necessary. The objective of the present study was to characterize twenty genotypes of cassava from an Active Germplasm Bank (AGB) in Pará state, Brazil, according to physicochemical characteristics of the root: moisture, ashes, total soluble solids, total titratable acidity, pH, total carotenoids, free and total cyanide, total protein, glucose, fructose, sucrose and starch. The values of moisture, ashes and soluble solids ranged from 60.53 to 71.96%, 1.22 to 1.80%, and 2.33 to 3.78%, respectively. Total titratable acidity ranged from 1.83 to 3.35% and pH from 5.68 to 6.50. The concentration of total carotenoids ranged from 2.34 to 9.76 μg g -1 , and total and free cyanide from 177.98 to 691.71 mg kg -1 and 20.29 to 135.19 mg kg -1, respectively. The protein concentration varied between 0.18 and 0.73%, which was considered low. The sugar figures ranged from 0.17 to 0.53%; 0.03 to 0.39%, and 0.14 to 0.40% for glucose, fructose and sucrose, respectively, and starch ranged from 18.65 to 36.01%. These results indicate a high phenotypic variation for chemical traits in samples of bitter cassava collected in Pará state, as well as potential for gains in genetic breeding. RESUMO: A mandioca (Manihot esculenta Crantz) é uma planta de origem na Amazônia brasileira que apresenta ampla variabilidade genética. Por ser um dos alimentos mais consumidos do mundo, esforços para geração de cultivares mais nutritivas são necessários. O objetivo foi caracterizar 20 genótipos de mandioca mantidos em um Banco Ativo de Germoplasma
