Abstract:
In an investigation to identify superior clones of sweet potato (Ipomoea batatas [L.\ Lam) suitable
for uplands, 36 clones were evaluated in a preliminary yield trials and 14 superior ones were clonally
selected and subjected to comparative yield trial for three years. The types SPC-13, SPC-18, SPC-20 and
Kanjangad gave higher tuber yield in comparison to others. SPC-13 had the highest total acceptability score
followed by Kanjangad which show their superior cooking quality. The results of the farm trial conducted
at 12 locations revealed the superiority of SPC-18 and Kanjangad with respect to tuber yield and low weevil
incidence. However, the farmers' preference and consumer acceptability were more towards Kanjangad due
to its attractive spindle shape and purple colour. Kanjangad was hence released as variety for cultivation
in the uplands of Kerala.
