Kanjangad - a sweet potato variety for uplands

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.
