KEANEKARAGAMAN KULTIVAR SEMANGKA [Citrullus lanatus (THUNB.) MATSUM. & NAKAI] DI SENTRA SEMANGKA NUSAWUNGU CILACAP
Abstrak: Watermelon [Citrullus
lanatus (Thunb.) Matsum. & Nakai] is a plant of Cucurbitaceae family which
is include in an annual plant. In Indonesia, watermelon has diversity in its cultivar
as can be seen from the stem, leaf, flower, and fruit morphology. This research
is aimed to find out the diversity and the similarity relationship of
watermelon cultivar in Nusawungu, Cilacap. A survey method was used in this
research by taking the samples with a random sampling technique (purposive
sampling). This research parameter consisted of stem, leaf, flower, and fruit
morphology of each watermelon cultivar. Data of watermelon cultivar morphology
were analyzed descriptively and then analyzed based on the similarity
relationship with UPGMA method (Unweighted Pair Group Method with Arithmetic
Mean) using the MEGA 5.05 software. The result of this research showed that
there were five watermelon cultivars namely C. lanatus ‘Farmers Giant’, C. lanatus
‘Nina’, C. lanatus ‘Black Orange’, C. lanatus ‘Torpedo’, and C. lanatus
‘Bintang’. There were two groups of watermelons based on phenetic analysis
namely group I consisting of C. lanatus ‘Torpedo’, C. lanatus ‘Black Orange’,
and C. lanatus ‘Nina’ cultivars, group II consisting of C. lanatus ‘Bintang’
and C. lanatus ‘Farmers Giant’. The closest similarity was between C. lanatus
‘Farmers Giant’ and C. lanatus ‘Bintang’ cultivars with the dissimilarity index
of 0,516. While the most distantly related was between C. lanatus ‘Nina’ and C.
lanatus ‘Farmers Giant’ cultivars with the dissimilarity index of 2,338.
