Near-infrared spectroscopy for early selection of waxy cassava clones via seed analysis.

ABSTRACT: Cassava (Manihot esculenta Crantz) starch consists of amylopectin and amylose, with its properties determined by the proportion of these two polymers. Waxy starches contain at least 95% amylopectin. In the food industry, waxy starches are advantageous, with pastes that are more stable towards retrogradation, while high-amylose starches are used as resistant starches. This study aimed to associate near-infrared spectrophotometry (NIRS) spectra with the waxy phenotype in cassava seeds and develop an accurate classification model for indirect selection of plants. A total of 1127 F₂ seeds were obtained from controlled crosses performed between 77 F₁ genotypes (wild-type, Wx_). Seeds were individually identified, and spectral data were obtained via NIR
