Provitamin A cassava clones were analysed for starch yield and critical quality attributes, to understand possible applications in the food industry. Total carotenoids content test ranged from 0.03-11.94 μg g-1 of fresh root. Starch 8.4-33.2 % correlated negatively (r = -0.588, P < 0.001) with content. Amylose (16.4–22.1%) didn't differ significantly (P ≤ 0.05) among clones. Meanwhile, total carotenoid had significant negative correlations pasting temperature, peak time, setback viscosities area. The reduced time temperatures high-carotenoid signifies reduction energy requirements yellow-fleshed roots when compared white-fleshed cassava. This attribute is desirable industry as it would reduce overall cost processing Furthermore, final carotenoid-rich lower than those roots, making provitamin suitable soft processing.
