Fitmawati. 2006. Taxonomic Status of Mangifera laurina and its Related Species. Floribunda 3(2): 29-37.-This study is aimed to investigate the taxonomic status of species related to M. laurina, to find out whether they represent a natural species or should be placed in several different species. The result showed that morphological phylogenetic analysis supported the idea for separating three monophyletic species (M. laurina, M. aplanata, M. lalijiwa), considering that M. rubropetala and M. indica are synonym, and defining two independent lineages of sister group (i.e. the clade of M. lalijiwa and the clade consist of M. indica, M. laurina, M. aplanata and M. rubropetala). Morphologically, M. lalijiwa is characterized by having glomerulate and glabrous inflorescence and tips of petal ridge free of the surface. In contrast, the other species usually posseses non-glomerulate and puberulous inflorescence and base or a half of base of petal ridge at free of the surface. Phylogenetic analysis of E-RAPD was incongruent with that of morphological analysis. However, the molecular phylogeny support whether that M. aplanata is separated from other species and that cultivars of M. lalijiwa are a monophyletic group.

Siti Ifadatin& Elvi Rusmiyanto PW. 2006. Genetic Diversity of Local Rice from West KalimantanBased on Isozyme Markers. Floribunda 3(2): 38-43.- A study on the genetic diversity has been conducted on eight cultivars of the local rice from West Kalimantan, namely Pulut Hitam, Pulut Melor, Pulut Sangai, Ringkak Serandah, Kak Cundong, Belait, Remunai and Payah Temakan. Isozyme analysis by using three Esterase Enzyme System (EST), malic dehydrogenase (MDH) and peroxidase (PER) resulted in 13 loci where 9 loci (69%) of them are polymorphic loci. Of the Esterase Enzyme System (EST), there were 2 band patterns (EST1 and EST2), in malic dehydrogenase enzyme system (MDH) there were 4 band patterns, while in the system of peroxidase (PER) there were 8 enzyme band patterns. In the analysis with three enzyme systems, there was no band pattern which is specific for a certain cultivar, so that they can be distinguished one and the other. The result of the clustering analysis on 8 local rice cultivars fromWest Kalimantan showed that all of the 8 cultivars were grouped into one group with similarity level 66%. The genetic similarity and the phylogeny of the rice could not be separated based on the origin. The result of this cluster analysis showed a tendency that Padi Pulut became one group which is different from non Padi Pulut.

Sobir, Siska Indriajaya Apriyani, Hajrial Aswidinnoor & Yuniarti. 2006. Comparative Analysis on Diversity Pattern of Pineapple Based on Phenotypic And RAPD Markers. Floribunda 3(2): 44-51. – Pineapple is mostly propagated through vegetative mean, and tend to have narrow genetic variability; therefore, powerful method is required to differentiate their genetic variability, and consequently 20 Ananas commosus accessions from nine locations inIndonesia and two accessions fromIvory Coast, were subjected to genetic variability analysis. This reseach utilizes their phenotypic performance and RAPD markers to evaluate the genetic distance and relationship among those accessions. Twenty-seven morphological characters and 29 RAPD bands had been utilized in this study. Cluster analysis revealed that based on morphological markers the accessions were separated accessions from 0.36 to 0.84 of similarity coefficient, and three primary groups could be distinguished at similarity coefficient of 0.35. Subsequently RAPD analysis has been separated the accessions at 0.62-1.00 of coefficient of similarity. From this analysis, three primary groups constructed at 0.67, and it is able to differentiate Queen and Smooth Cayenne type accessions. The concurrence analysis on morphological and RAPD analysis, showed the very weak Rohlf correlation value (r=0.0747), which indicated that grouping of pineapple accessions should be combination of morphological characters and RAPD analysis. Combination morphological showed that accessions distributed from 0.49 to 0.81 of similarity coefficient level, and at 0.56 level similarities, the pineapple accessions were clustered into four primary groups and it is able to differentiate Queen and Smooth Cayenne type accessions.

Nina Ratna Djuita & Muhammad Jusuf. 2006. The use of Multivariate Analysis in Numerical Taxonomy : Case of Two, Soybean Cultivars and Their Generation (F2). Floribunda 3(1): 10-18. --- Multivariate analysis was applied to the morphological data of Slamet and Nokon Sawon cultivars and their generation (F2). This research was intended to compare multivariate analysis namely principal component analysis and disciminant analysis to two cultivars above and their generation. The first analysis resulted 2 and 7 principal components of covariance and correlation matrix for original data while data transformed revealed 5 and 8 principal components of covariance and correlation matrix respectively. Based on discriminant analysis, Nokon and Sawon’s cultivar can be successfully classified as a single group different from the rest.

LEAF ANATOMY CHARACTERS IN THE TAXONOMY OF PHALAENOPSIS AND ITS RELATIVES IN INDONESIA Nina Dwi Yulia; Juliarni Juliarni

Nina Dwi Yulia & Juliarni. 2006. Leaf Anatomy Characters in The Taxonomy of Phalaenopsis and its Relatives in Indonesia. Floribunda 3(2): 52-56.- Stomatal size, epiderm cell shape and structure and leaf thickness in Paraphalaenopsis, Doritis and Phalaenopsis are different. However, those characters are similar in Phalaenopsis and Kingidium. Cladistic analysis of Phalaenopsis and its relatives using Hennig86 produced a cladogram with 10 steps and ended with the 3 closest genera, Doritis, Kingidium and Phalaenopsis.

Sobir, Cynthia Rozyandra & Kusuma Darma. 2006. Morphological varibility of collection Banana in South of Lampung resident. Floribunda 3(1): 19-27. --- Lampung was famous as main production of banana in Indonesia, particularly in South of Lampung regency. In order to ellucidate the genetic basis of banana, it was collected 21 banana germplasms from Lampung Selatan and grown in Pasir Kuda Research Station of Center for Tropical Fruit Studies. The potential of the germplasm was elucidate through phenotipyc variability analysis by employing 41 morphological characters. Dendrogram generated using SAHN-UPGMA (Sequential, Agglomerative, Hierarchical, and Nested-Unweighted Pair-Group Method, Arithmetic-average) indicated that the evaluated accessions separated at 0.56 coefficient of dissimilarity, subsequently at 0.45 level coefficient of dissimilarity, the accessions divided into five primary groups. A Principal Component Analysis resulted that 81.0120% of genetic variability successfully revealed by ten principles components, score plot based on first and second principle component described 61.26% of variability and split the accessions into six primary groups. These result indicated that grouping pattern of both analysis not equal, this was probably because of 41 component simplified into two component that described lower than 70% of variability. However, the grouping has been successfully revealed the putative genome type of the collected banana accesions.
