ABSTRAK
Penelitian ini bertujuan untuk menguji penampilan karakter morfologi
daun dan bunga dari tiga spesies bengkuang (P. erosus, P. Ehipa, dan P.
tuberosus) di Jatinangor Jawa Barat. Dua belas genotip P. erosus, enam
genotip P. ahipa dan empat P. tuberosus ditanam dalam rancangan acak
kelompok dengan dua ulangan. Analisis multivariat meliputi analisis
komponen utama dan kluster yang dilakukan berdasarkan 18 karakter
morfologi daun dan bunga. Hasil penelitian menunjukkan, bahwa
analisis
komponen
utama
dan
analisis
kluster
mampu
mengelompokkan secara jelas tiga spesies bengkuang yang berbeda.
Morfologi bunga adalah karakter utama dibandingkan morfologi daun
sebagai diskriminan diantara tiga spesies bengkuang.
Kata Kunci: Analisis multivariat, bengkuang, Pachyrizus spp
MULTIVARIATE ANALYSIS ON FLOWERS AND LEAVES
CHARACTERS OF THREE YAM BEAN SPECIES (Pachyrizus spp.)
POPULATION
ABSTRACT
The objective of this study was to analyse flowers and leaves
morfological characters of three yam bean species (P. erosus, P. ahipa,
and P. tuberosus) in Jatinangor West Java. Twelve P. erosus genotypes,
six P. ahipa genotypes, and four P. tuberosus genotypes were planted
on randomized block design with two replications. Multivariate analysis
i.e., principal component and cluster analysis was used to grouping the
three species of yam bean based on 18 characters of flowers and
leaves performances. Both principal component and cluster analysis
clearly separated the three species. The analysis showed identification
of floral variables as the main characters to discriminate between
species.
Key words : Multivariat analysis, yam bean, Pachyrhizus spp
