The similarity coefficient values (8.47) of 69 accessions were divided into 9<br />
clusters by using R-program version 2.6.1. Here, the majority of the accessions is<br />
shown in Table 12.<br />
Cluster I: the first cluster is the largest cluster with 19 accessions. This account<br />
for the 27.14 % of the total accessions stratified. This cluster represents the majority<br />
of mixture accessions belonging to Solanum melongena, S. aculeatissimum and<br />
S. xanthocarpum. This cluster is heterogeneous for 10 traits except for plant growth<br />
habit. The unique of this cluster is by having the broader than long of fruit length to<br />
breadth ratio and brownish yellow seed.<br />
This cluster can be divided into four subclusters. Subcluster A is composed of<br />
2 accessions (2.90 %) belong to S. melongena collected from Thailand. This<br />
subcluster is characterized by having weak leaf blade lobbing, the acute (~ 45°) of<br />
leaf blade tip angle and grey yellow seed. Subcluster B is the only one accession of<br />
S. melongena collected from Thailand. This subcluster is characterized by having<br />
intermediate (~3 mm) relative style length, insert of style exertion and as long as<br />
broad fruit length and breadth ratio. Subcluster C is a group of 6 accessions (8.70 %)<br />
heterogenous accessions belong to S. melongena, S. aculeatissimum and<br />
S. xanthocarpum collected from Thailand (5 accessions) and one accession from<br />
Malaysia. This subcluster is heterogenous for 7 traits except for plant growth habit,<br />
leaf blade lobbing, relative style length and fruit yield per plant. Subcluster D was<br />
considered to be the most diverse with 10 accessions (14.49 %). Subcluster D<br />
consisted of S. melongena collected in Thailand (7 accessions), Laos (1 accession)<br />
and Vietnam (1 accession) and S. xanthocarpum collected from Thailand (1<br />
accession).<br />
Cluster II: the second cluster consists of 6 accessions. This account for the<br />
8.70 % of the total accessions stratified. This cluster is a group of 3 accessions<br />
belonging to S. melongena, 2 accessions belonging to S. xanthocarpum and one<br />
accessions of S. aculeatissimum. This cluster is homogenous for plant habit, style<br />
exertion and seed color. The unique of this cluster is having brownish yellow seed.<br />
