Variability in carotenoid content among introduced yellow-fleshed cassava clones
Abstract

Cassava is important in semi-arid Kenya. However, the crop
is low in micronutrients including beta-carotene. A total of 129
high beta-carotene cassava clones from the International
Institute of Tropical Agriculture (IITA) were established in
Kenya. Root samples were collected for carotenoid
quantification by high performance liquid chromatography and
spectrophotometry methods. Root yield of the clones ranged
from 26.5-85 tons/ha. Mean root cyanogenic potential was 3.84.
Carotenoid content ranged from 23-2232 µg/100g. The clones
were ranked on basis of carotenoid content, root yield,
cyanogenic potential and availability of planting material. The
top ten clones in the rank were selected for incorporation in
the carotenoid content trait in local varieties.
