II. Nominal traits (qualitative traits)
The most frequent traits among the 69 accessions in Southeast Asia
considered are present in Table 11. The traits of plant growth habit was intermediate
(approximately 94.20 %), leaf blade lobbing was intermediate (approximately
39.13 %), leaf blade tip angle was intermediate (approximately 55.07 %), relative
style length was long (approximately 97.10 %), style exertion was exertion
(approximately 81.16 %), fruit length and breadth ratio was as long as broad
(approximately 72.46 %), fruit color at commercial ripeness was green
(approximately 68.12 %), fruit color at physiological ripeness was deep yellow
(approximately 42.03 %), fruit flesh density was loss (crumbly) (approximately
46.38 %), fruit yiled per plant was low (~ 500 g)(approximately 75.36 %) and seed
color was light yellow (approximately 46.38 %). However, this indicateas that most of
Solanum spp. have intermediate plant growth habit and long relative style length.
Furthermore, leaf blade lobbing, fruit color at physiological maturity, fruit flesh
density and seed color was more variation depend on species.
However, S. melongena is the highest population on plant growth habit
(28.49 %), leaf blade lobbing (23.19 %), leaf blade tip angle (18.84 %), relative style
length (26.09 %), style exertion (14.49 %), fruit color at physiological ripeness
(28.49 %) and fruit yiled per plant (21.74 %). However, S. ferox is the highest
population on fruit length and breadth ratio (24.64 %), fruit color at commercial
ripeness (24.64 %), fruit flesh density (24.64 %) and seed color (24.64 %). In addition,
S. torvum is the highest population on style exertion (14.49 %).
Therefore, following the most frequent of qualitative trait, S. melongena
was the major group of 69 accessions of Solanum spp. and the second major group
was S. ferox and the third major group was S. torvum.
