THESIS

Subcluster A is the only one accession of S. sanitwongsei collected in
Thailand. This subcluster was separated from the other subcluster because it is the
only one subcluster with upright plant growth habit and strong leaf blade lobbing,
obtuse (~ 110°) leaf blade angle and very low yield per plant. Subcluster B is
represented by TS02495 (S. indicum) collected from Thailand. The unique of this
subcluster is for acute (~ 45°) leaf blade angle and very low yield per plant.
Subcluster C is the homogenous of the two accessions of S. indicum collected from
Laos, this can be separated from subcluster D by having the obtuse (~ 110°) leaf blade
angle. Subcluster D is the largest subcluster with 5 accessions collected from Laos
merging at 100 % similarity which.
This cluster formed its own, separated stratified clusters. It could be
recognized from the rest by very strong leaf blade lobbing, deep yellow fruit at
ripening and very loose (spongy) fruit flesh density.
Cluster VIII is a group of three accessions, belong to S. melongena collected
from Laos. The unique of this cluster by having the purple fruit at ripening, dense
fruit flesh density and grey yellow seed.
Cluster IX is the only one accession, belong to S. mammosum collected from
Malaysia. The unique of this cluster is strong leaf blade lobbing, acute (~ 45°) leaf
blade angle, insert style exertion, slightly longer than broad of fruit length to breadth
ratio (Appendix A), deep yellow fruit at harvesting, yellow orange fruit at maturity,
average density of fruit flesh density and black seed. Hence, Cluster IX was
considered to be the last cluster that fuses with the rest of the clusters. This indicated
the cluster IX had nominal traits considering being almost different from the other
clusters.
