Abstract

Mango is a tropical fruit plant. Distribution center of mango species in Indonesia are in Sumatra and Borneo. Among the species, Mangifera indica L. has more varieties than most other species. Eight varieties of M. indica L. which are Blenyik Bulat, Wader, Bapang, Gondo Lumut, Madu, Endog, Gandik Luyung and Krasak Candi has been studied to recognize the phenotypic character of superior germplasm of mango varieties. Qualitative and quantitative characters of varieties have been measured. Varieties of Madu, Endog and Krasak Candi has a sweet fruit flavor and relatively non-fibrous with the highest scoring value 14 and 12. Quantitatively, it is known that the size of mango varieties under study pertained small, range from 0.12 to 0.3 kg. However, Blenyik Bulat variety with very small fruit has a very attractive appearance, yellow when it is ripe with a uniform color. Based on the ratio between the weight of fruit peel and seeds, it is known that the varieties have thick flesh, heavy pieces of meat more than 60%, variety Blenyik Bulat 80%, Wader 67%, Madu 73%, Bapang 96%, Gondo Lumut 96%, 94% Endog, Gandik Luyung 93%, 89% Krasak Candi. From phenotypic characters of mango variety, we can conclude that the variety of Madu, Endog, and Krasak Candi are quite excellent and their fruit can be developed for domestic consumption, as they have sweet taste. While for other varieties such as Blenyik Bulat, Gondo Lumut, and Bapang, can be developed for processing fruit as juice or dessert even can be developed for export consumption for example to Europe and Australia, as they have sour taste.     Keyword: Manggo, Character, Phenotypic.

Abstract

Bioinformatics are a reliable method to trace biological information in the molecular level including the analysis of molecular phylogeny relationship of species. This paper discuss about the phylogeny relationship of eleven species of Phalaenopsis (Orchidaceae) based on internal transcribed spacer (ITS1 and ITS2) gene, 5.8 ribosomal DNA by bioinformatics applications. The method of this study is a database search in Gene Bank through the NCBI website (http://www.ncbi.nlm.nih.gov) to search nucleotide data and DDBJ (http//www.ddbj.nig.ac. jp) for the use of software BLAST and the EBI (http://www.ebi.ac.uk) for nucleotide alignment of similarity search. Cladogram shows that P. javanica and P. patherina have a very close relationship. Both species are also still closely related to P. cornu-cervii. Species P. modesta, P. tetraspis and P. lueddemannian are separated each other that can be revealed to have distant phylogenetic relationship than other species in the genus. Species P. amboinensis form a cluster with the species P. floresensis and P. mannii. However, P. sumatrana was closely related to P. corningiana. The cladogram showed that formation among Phalaenopsis species was not apparently grouping. Moreover, there is a large group consisting of P. amboinensis, P. Sumatrana, P. cornu-cervi, P. pantherina, P. floresensis, P. mannii and P. corningiana, while P. modesta, P. tetraspis and P. lueddemanniana were not clustered into the group.Keywords: Bioinformatics, phylogenetic relationship, Phalaenopsis, databases, internal transcribed spacer (ITS) gene.
