Mosses is a species of exotic and charming with a unique combination of characteristics of each of its members. In Indonesia, this species can grow lush and abundant, however it was not a lot of investigate for content of this plant. This study aims to determine the diversity of bryophyta views by morphological and secondary metabolites. This research used descriptive method with qualitative approach. Sampling was conducted in four locations in Bogor Indonesian Regency by randomly. Analysis of the data used descriptive analysis to find the value of Rf (Retardation Factor) which converted into a form of the data with UPGMA (Unweighted Pair Group Method with Arithmetic Mean) model. The results showed that four types has been founded, namely Dicranella sp., Funaria hygrometrica Hedwig, Bryum billardierii Schwaegr and Pogonatum contortum Brid. Profile content of secondary metabolites showed that Dicranella sp., B. Billardierii, F. hygrometrica and P. contortum contained alkaloids, phenolics, triterpenoids/steroids and terpenoids. Kinship at the level of morphological traits and characteristics content of the secondary metabolites presented that Funaria hygrometrica Hedwig and Bryum billardierii Schwaegr (66.67%) have a closer kinship than among Dicranella sp and Funaria hygrometrica Hedwig (63.64%) meanwhile between Bryum billardierii Schwaegr and Pogonatum contortum Brid (51.52%).

Objetivou-se discernir populações caprinas de cinco ilhas da República de Cabo Verde (n=533) por meio de dados biométricos e análises estatísticas. Foram avaliadas 16 características de fêmeas adultas, através da estatística descritiva simples, análise de variância, teste de multicolinearidade, distância generalizada de Mahalanobis (D²) e algoritmo UPGMA (Unweighted Pair Group Method Arithmetic Mean). Após o teste de multicolinearidade foi identificada e descartada a variável profundidade torácica. As D² foram calculadas com base nas 15 medidas biométricas. O maior valor da D² foi entre as populações das ilhas do Fogo e São Nicolau (22,73), e a menor D² foi entre Santo Antão e São Vicente (3,71). O dendrograma a partir de 15 variáveis em cinco populações colocou as cabras da ilha de Fogo em ramo a parte das demais. Agruparam-se num ramo as cabras das ilhas de Santo Antão e São Vicente. Este resultado está de acordo com a distância geográfica entre as ilhas de Cabo Verde e o histórico recente de intercâmbio de animais entre elas.

AbstractWe studied the songs of Wedge-tailed Sabrewings (Campylopterus curvipennis) in six localities from central Veracruz, Mexico, to document structure and variation within and between singing groups in the same geographic region. Wedgetailed Sabrewing songs were acoustically, structurally, and behaviorally complex, rivaling those of other taxa with complex signals. Songs of individual birds were composed of >45 well-differentiated and structurally complex syllables. We found 239 different syllable types across eight recorded singing groups of Wedge-tailed Sabrewings (∼20 syllable types per singing group), with the greatest versatility recorded in hummingbirds to date. The acoustic variation (15 variables) was summarized in three principal components (58% of acoustic variation), in which intragroup variability accounted for most of the observed variation. We found significant differences between and within groups in terms of syllable sharing (Jaccard’s similarity coefficient). Individuals generally shared >50% of syllable types within groups, whereas syllable sharing was <10% between individuals from different groups. The same microgeographic pattern was supported in a UPGMA (unweighted pair-group method with arithmetic mean) analysis where individual songs from each singing group clustered separately. However, songs recorded at the same location differed between seasons, which suggests that this species does not exhibit geographically distinct dialects that are consistent across time. The interplay among this species’ social system, distribution of its floral resources, and microgeographic and temporal variation of its song requires further research.

Abstract Random Amplified Polymorphic DNA (RAPD) analysis was carried out on 19 Azerbaijan tomato genotypes, both cultivars and local populations. A total of 26 amplified products were revealed by 6 primers. The genetic similarity among evaluated genotypes ranged from 0.188 to 1.000. The lowest similarity was observed between cultivars ‘Azerbaijan’ and ‘Shakar’ (0.188), while the highest between ‘Elnur’ and ‘Garatag’ (1.000). The Unweighted Pair Group Method with Arithmetic Mean (UPGMA) cluster analysis based on Jaccard’s similarity coefficient divided genotypes into four main groups. The first group was the largest and consisted of 12 genotypes, while the fourth group was the smallest consisted of 1 genotype only. The most polymorphic primer was OPB-18 that presented a genetic diversity index of 0.823, while the least informative was primer OPG-17 with an index of 0.349. The average genetic diversity calculated from RAPD data was 0.665.

Abstract: The objective of this work was to quantify the genetic divergence among accessions of white-type acai palm, through morpho-agronomic characters. The accessions belong to the active acai palm germplasm bank of Embrapa Amazônia Oriental. Thirteen characters were evaluated in 26 accessions, originated from six municipalities in the state of Pará, Brazil. The data were subjected to deviance and multivariate analyses, based on the average Euclidean distance, and were grouped by Tocher’s method and the unweighted pair group method with arithmetic mean (UPGMA). The accessions differed for eight characters. The distances among accessions ranged from 0.64 to 2.62, with an average of 1.36, and four groups were formed by Tocher’s method and two by the UPGMA. Seven major components explained 88.03% of the variation, whose graphic dispersion showed the tendency of forming four groups. The characters weight of 100 fruits, number of rachillae per bunch, and fruit yield per bunch contributed the most to the divergence, and the accessions from the municipalities of Breves, Curralinho, and Limoeiro do Ajuru were the most divergent. Therefore, the accessions of white acai palm show strong divergence and variability, which favor the selection of desirable individuals.

Bananas and plantains (Musa spp.) constitute staple food for over 20 million people in Democratic Republic of Congo (DRC). Since 1960, DRC is considered as a secondary centre of plantain diversification with few unknown accessions kept in the INERA-Mulungu genebank. Through similarity coefficients, cluster (unweighted pair group method with arithmetic mean, single, complete, sequential, agglomerative, hierarchical and nested design/clustering procedure) and/or multivariate analyses, numerical morpho-taxonomy has established that this diversity is composed of 37 different accessions. Each accession expressed 98 characters among the 401 possible character states, thus providing 39,298 feature patterns (data points). The 98 characters included 32 vegetative and 66 male and female inflorescences. The accessions were clustered into three genomic groups (AAA, AAB and AABB). Subjective classification ascertained nine subgroups: AAB-Silk, AAB-Pome, AAB-Plantain, AABB-Pisang Awak, AAA-Cavendish, AAA-Ibota, AAA-Gros Michel, AAA-Green-Red and AAA-Lujugira-Mutika. Three subgroups were further divided into nine clone sets which consisted of: Dwarf and Giant Cavendish, French and Horn Plantains, and Musakala, Nfuuka, Nakitembe, Nakabululu and Beer/Mbidde within Lujugira-Mutika. Numerical morpho-taxonomy effectively indicated a relationship between the DRC and Tanzania's Musa diversity. For example, the accessions ‘Kamaramasengi’ and ‘Isangi’ were found to be similar to ‘Kisukari’ (AAB-Silk) and ‘Ngego I’ (AAB-French) common in the Tanzanian Southern Highland. Likewise, the accessions Kimalindi-fupi, Kimalindi-ndefu and Jamaica of Tanzania were duplicates of Bakurura (Kigurube), Cavendish of Butuza and Gros Michel in DRC, respectively. Moreover, numerical morpho-taxonomy confirmed the pedigree of AAB-Prata (Cibwalo) in FHIA 17 and FHIA 23 and the closeness of the ancestors of Yangambi Km5 and Gros Michel. Furthermore, numerical morpho-taxonomy established AA-Mshale malembo as one of the AAA-Lujugira-Mutika parents. Molecular investigations are finally required to confirm the genomes.

Specimens of all known taxa and putative entities belonging to the Banksia spinulosa complex were collected from Kuranda in northern Queensland, western to central Queensland and down the eastern coast of Australia to Wilsons Promontory in southern Victoria. These specimens were used to investigate morphological variation in habit, stems, leaves, inflorescences, fruits and seeds in the complex. Phenetic analysis (unweighted pair-group method with arithmetic mean, UPGMA, clustering and semi-strong hybrid multi-dimensional scaling, SSH–MDS, ordination) was performed on the full dataset of 233 entities using 33 characters (18 quantitative, two binary and 13 multistate). To facilitate visualisation of patterns in both clustering and ordination, we also analysed subgroups based on the results of the phenogram from the full dataset. The results showed that the five known and described taxa are phenetically distinct, viz. B. collina sens. str., B. cunninghamii sens. str., B. neoanglica, B. spinulosa and B. vincentia, and provided support for a further 12 morphometrically diagnosable entities, four of which could not be diagnosed with simple combinations of character states and require further investigation. The present study has highlighted that there is much more hidden morphological diversity in the B. spinulosa complex than has previously been recognised in any of the current competing taxonomies.

This investigation was aimed at exploring the genetic diversity and relationship among nine Brassica varieties, namely BARI Sharisha-12, Agrani, Sampad, BINA Sharisha-4, BINA Sharisha-5, BARI Sharisha-13, Daulot, Rai-5, Alboglabra using Random Amplified Polymorphic DNA (RAPD) markers. In total, 59 reproducible DNA bands were generated by four arbitrary selected primers of which 58 (98.03%) bands were proved to be polymorphic. These bands ranged from 212 to 30686 bp in size. The highest proportion of polymorphic loci and gene diversity values were 37.29% and 0.1373, respectively, for BARI Sharisha-12 and the lowest proportion of polymorphic loci and gene diversity values were 8.47% and 0.0318, 8.47% and 0.0382 for BINA Sharisha-4 and Rai-5, respectively. A dendrogram was constructed using unweighted pair group method of arithmetic mean (UPGMA). The result of cluster analysis indicated that the 9 accessions were capable of being classified into 2 major groups. One group consists of BARI Sharisha-12, Agrani, Sampad, Daulot, Rai-5, Alboglabra. where Daulot and Rai-5 showed the lowest genetic distance of 0.049. And another group contains BINA Sharisha-4, BINA Sharisha-5, and BARI Sharisha-1 3, where BINA Sharisha-5 and BARI sharisha-13 showed genetic distance of 0.071. Key Words: RAPD, Brassica, genetic distance, polymorphic band. DOI: 10.3329/bjar.v34i3.3976 Bangladesh J. Agril. Res. 34(3) : 493-5032, September 2009

Morphometric character analyses and RAPD was used to discriminate and ratify the status of three populations of Indian salmon, Polydactylus plebeius along the coromandel coast of India. Morphometric analyses showed a clear pattern of differentiation between the stocks and revealed the discreteness of two groups, southern stock (Pazhayar) and northern stock (Cuddalore). The univariate analysis of variance showed significant differences between means of the samples for most morphometric descriptors. A total of 1077 scorable bands were produced using all ten arbitrary primers in three populations. An un-weighted pair-group method with arithmetic mean (UPGMA) dendrogram was constructed based on genetic values to show the genetic relationship among the three populations. The genetic diversity (H) of P. plebeius in Cuddalore was more (0.0733 ± 0.0648) than Pazhayar (0.0609 ± 0.0416) and Vellar (0.0613 ± 0.0344) populations. All the three populations had significantly (p

The objective of this study was to characterize sixteen genotypes of P. insignis available in the Embrapa Meio-Norte germplasm collection (Teresina, Piauí, Brazil) with respect to 33 morphological traits relating to leaves, flowers, branches, fruits and seeds. Phenotypic variance among genotypes was estimated using the Mahalanobis distance technique and the unweighted pair group method with arithmetic mean analysis (UPGMA). The method of Singh (1981) was used to determine which of the traits contributed most to diversity within genotypes. The occurrence of phenotypic variability among P. insignis genotypes indicated that it would be possible to achieve positive gains with selection. The most distant genotypes were BGB 16 and BGB 48, while crosses between genotype BGB 48 and genotypes BGB 32 and BGB 56 offers the greatest potential as parental types for this fruit tree breeding programs . The flesh content, ovary and fruit length , ratio between fruit length and diameter were the characters that most contributed to diversity among the studied genotypes.
