Judul: Analysis of agronomic characters and isozyme of physic nut (Jatropha curcas L.) at wet climate
Abstrak: The research objective was to determine agronomic characters influencing productivity and genetic variability of several physic nuts in high rainfall area. The research used Completely Randomized Design with three replications of genotypes as follows IP-1A, IP-1M, IP-2P, Lombok Timur, Lombok Tengah, Sumbawa, and Bima genotypes. The direct or indirect effect of each characters was determined by path analysis. Analysis of isozyme experiment of the eight genotypes was also conducted. The experiment showed that the most productive physic nut in high rainfall area was the IP-2P genotype (558.33 kg/ha). The agronomic characters influencing the yield were number of secondary branches, number of productive branches, total leaves, number of inflorescence, number of fruits/plant, fruit weight, seed length, number of seeds/plant, dried seed weight, and weight of 100 seeds. Overall, the most important characters contributing to weight of dry seed per plant is the number of inflorescence (X7) and number of seed per plant (X12), as shown by their positive direct influence and correlation coefficient (P7y =0.51; r7y=0.98) and (P12y=1.10; r12y=0.99). It is concluded that the two characters can be used as the selection criteria for yield. Genetic variability based on qualitative characters was 0-14%, quantitative 17-81%, the isozyme analysis 2-25%, for combined qualitative characters with the isozyme was 1-13% and for combined qualitative characters, quantitative characters and isozyme was 6-33%.

Judul: Genetic Evaluation of Yield Potential and Other Important Characters in Physic nut (Jatropha curcas L.) to Support High Yielding Variety Development
Abstrak: To develop high yielding varieties of physic nut (Jatropha curcas L.), an important oil producing crop needed to support development of renewable energy resources program in Indonesia requires genetic evaluation of the germplasm. The collected genetic data are important for designing the appropriate Jatropha breeding program. The objectives of this research were to evaluate: 1) morphological and yield potential performances of selected J. curcas genotypes, 2) genetic variance and heritabilities of important characters and their correlation with yield, 3) combining ability of selected genotypes and their heterotic values, 4) existence of inbreeding and outbreeding depression, and 5) inheritance of hermaphrodite flower characters of monoecious and tri-monoecious parent types. Results of the experiment indicated that 60 J. curcas genotypes evaluated exhibited a wide variation in number of branches, days to flowering, number of inflorescences, bunches, fruits and nuts per plant. Number of branches, inflorescences and bunches were positively correlated with number of fruits and nuts per plant while days to flowering was negatively correlated with all generative characters. The ten selected genotypes exhibited high phenotypic variation in number of branches, days to flowering, number of inflorescences, bunches and fruits. The coefficient of variation (CV) for all of these characters were generally > 20 %. Days to flowering, number of inflorescences, bunches and fruits exhibited wide genotypic variation with genetic variability coefficients (GVC) as high as 21,89; 29,77; 32,08; and 33,75, respectively. They also showed a wide genetic variability (2g > 2 2g) and high broad sense heritability (h2bs  50). Therefore, days to flowering, number of inflorescences, bunches and fruits could be used as selection parameters. Moreover, number of total branches was especially usefull since it showed positive correlation to a number of yield component character. The ten selected parents exhibited different values of combining ability and they all had DGU/DGK > 1. Such value indicated a greater additive gene effects than the non-additive ones. High yielding genotypes, such as 3012-1 and PT 15-1, generally exhibited high GCA for a number of characters (days to flowering, width of canopy, number of total branches, inflorescences, and fruits) while medium yielding genotypes, such as PT 33-2, exhibited high GCA only for number of inflorescences, total branches, and fruits characters. Those three promising genotypes could be selected and used as a base population to develop high yielding synthetic J. curcas variety with the characteristics of early flowering. Results of the experiment also demonstrated that crossing among high and medium yielding parents were able to potentially produce very high yielding progenies. Depending on the observed characters, either selfing or outcrossing may results in depression in several F1 populations. Outbreeding depression reduced up to 31 – 76 % of fruit numbers yielded per plant. In the last experiment, hermaphrodite flower occured mostly at 6 months after sowing and the frequencies it occurrences ranged from 7-83 % of the total flowers. Hermaphrodite flowers of tri-monoecious plant exhibited better fruit set than that of monoecious. Hermaphrodite flowers exhibited higher fruit set (average: 80 %) than those of female flowers (average: 50 %), respectively. Hermaphrodite flowers were not maternally inherited and

Abstrak: Distemper merupakan penyakit infeksius pada bimbingan anjing yang menduduki tempet teratas dan penyakit ini tersebar di seluruh bagian dunia dimana terdapat anjing-anjing yang dipelihara, terutama pada anjing-anjing muda di kota-kota besar, pada kelompok-kelompok anjing atau pada situasi lain dimana banyak terdapat kontak antara anjing. Penyakit ini disebabkan oleh virus yang termasuk dalam famili Paramyxoviridae dan genus Morbilivirus. Infeksi virus ini sering disertai oleh infeksi sekunder oleh kuman Staphylococcus, streptococcus, Brucella bronchiseptica dan kuman Salmonella, inilah yang kadang-kadang sebagai penyebab kematian.
