dc.description.abstract | SUMMARY
Taro (Colocasia spp.) is an aroid plant which has long been cultivated in
Kalimantan. This plant is considered as one of the oldest forms of cultivated plants
in the region. Information about its morphological variability is needed to develop
taro breeding population as future alternative crop. The aim of this research was to
determine the morphological characters variability of taro in Kalimantan, Indonesia
based on phenetic analysis approach. Leaf, petiole, stolon and corm samples were
collected in all Indonesian provinces of Kalimantan. Similarity index was measured
using the gower general similarity coefficient and cluster analysis was carried using
the unweighted pair group method using arithmetic average (UPGMA). A
dendrogram and principal component analysis (PCA) were constructed using
Multivariate Statistical Program v.3.1 software. Around 123 accessions had been
collected and evaluated using 39 morphological traits. Taro in Kalimantan consists
of C. esculenta, C. affinis, Colocasia sp and Colocasia wild type. C. esculenta is the
most widely used as staple food by local residents in Kalimantan. It has two
botanical varieties. Fifty two from all the accessions are local cultivars that
developed from C. esculenta varieties. Cluster analysis revealed Coefficient
Similarity of taro ranging from 0.615 to 0.974, and divided into two major clusters.
The first cluster has Colocasia sp as its single subgroup, while the second cluster
has six subgroups including C. esculenta, C. affinis and Colocasia wild type. In
Kalimantan, taro leaf especially petiole colour has significant influent in taro
grouping. | en_US |
