Indonesia has a variety of eggplant germplasms and is considered
as one of the largest producing countries in the world. The study was
conducted to assess the variation of 21 accessions and 2 commercial
cultivars of eggplant from Indonesia based on 30 macromorphological
and 8 leaves micromorphological characters. Cluster analysis was
conducted by UPGMA (Unweighted Pair Group Methods with Arithmetic
averages) to create a dendrogram and construct eggplants grouping.
PCA (Principal Component Analysis) was also performed to define the
role of each character in the group by using MVSP (Multivariate Statistical
Program) v.3.1 software. Results showed that eggplant accessions have
macromorphological variation in fruit curvature, fruit shape, fruit apex,
and fruit color, as well as leaves micromorphological characters such
as the epidermal wall, trichome shape, and stomata type. Dendrogram
based on macromorphological characters divided the accessions into 2
groups: curved and non-curved fruit groups. The non-curved fruit group
divided into more spiny and less spiny leaves sub groups. Dendrogram
based on leaves micromorphological characters divided the accessions
into 2 groups based on the epidermal wall, trichome shape, and stomata
type. Eggplant grouping doesn’t occur based on the origin of collection
areas indicating that its variability isn’t affected by the environment.
