Progeny identification is the important step that should be done after hybridization. However, polyploidy, aneuploidy and the high chromosome segregation in sugarcane which results various phenotypic characteristics variation and environmental effects become limiting factors to identify the progenies based on morphological characteristic. Microsatellite as one of molecular marker which has codominance inheritance, multiallelic, abundant in the genome and does not influenced by environmental factor is the best tool to asses the crossing fidelity accurately. This research aimed to identify the possibility of genetic marker of Saccharum spp. and Erianthus sp. on their hybrid using microsatellite molecular marker. This study was carried out in Molecular Genetic laboratory, Indonesian Sweetener and Fiber Crops Research Institute (ISFCRI) Malang, from August 2016 to July 2017. Eighty-six (86) F1 intraspecific and interspecific progeny, three commercial sugarcane varieties (PSJT941, PS881 and VMC7616) and two wild types (S. spontaneum dan Erianthus sp.) were assessed genetically by three microsatellite markers. Identification of microsatellite genetic markers was conducted by comparing the visualization band results from electrophoresis of each male and female parent through their progenies. All primers could identify Saccharum spp. and Erianthus sp. genetic markers. There were one to eleven Saccharum spp. and Erianthus sp. genetic markers could be identified such as 2-11 PS881-specific alleles; 2-3 VMC7616-specific alleles; 1-5 PSJT941-specific alleles; two S. spontaneum-specific alleles and 1-2 Erianthus-specific alleles. These findings could be used as the advance genetic marker of microsatellite in sugarcane breeding to asses the cross fidelity.

Correct Understanding

Abstract Environmental quality has the potential to influence dispersal if cost of dispersing is outweighed by cost of staying. In that scenario, individuals experiencing different conditions in their natal area are expected to differ in their dispersal. Even if there is wide agreement that reasons behind the dispersal decision are multiple, it is often less clear what conditions actually add to the observed dispersal behavior. The scale at which the dispersal behavior is analyzed can also be of crucial importance for a correct understanding of the dispersal process. Furthermore, in long-lived species factors influencing dispersal behavior of juveniles may differ from those adding to dispersal of adults. Using 12 years of banding data (1989–2000), we studied dispersal behavior of Northern Goshawks (Accipiter gentilis) hatched over a wide area in Finland in relation to local demographic and ecological conditions. Hatching rank and hatching date added to the probability of leaving in the first place; whereas hatching date, local prey availability, and sex of the disperser were related to dispersal distance. Among adult birds (+3 years), none of the analyzed variables were related to distance; whereas the probability of remaining locally was related to local grouse density in the hatching year (for males only). Results show that the combined effects of factors working at several levels act together on dispersal behavior in Northern Goshawks and highlight the importance of studying different age classes separately in long-lived species. In summary, our results suggest that goshawk individuals distribute themselves spatially in parallel with factors determining the costs and advantages of dispersing where philopatry seems to be connected to factors positively associated with survival; but to test the validity of that idea, more data on fitness consequences of dispersal are needed.

The brood size in the Finnish Northern Goshawks seems to be associated with the breeding habitat and the availability of suitable prey. In this study, we examined these relationships in three study areas of different landscape structure in southern Finland, including a recently colonized urban area. The most abundant prey categories found in the food remains of the goshawk included corvids, turdids, columbids, gallinaceous birds, and squirrels. Corvids dominated in the diet samples of all the study areas. The number of turdids and columbids in the samples was significantly higher in both the rural and the urban habitats than in the wilderness area. The number of gallinaceous birds was significantly higher in the wilderness area than in other habitats. Gallinaceous birds, particularly tetraonids, the traditional staple food of the Northern Goshawk in Finland, seemed to be largely compensated by corvids in the wilderness area and by corvids and columbids in the rural and urban areas. The amount of corvids in prey showed a positive relationship with brood size, suggesting some particular importance of this prey in the goshawk diet. In all, diet seemed to explain partly between-landscape variations in the brood size of the goshawk. The brood size was significantly higher in the urban landscape than elsewhere.

To investigate the influence of chemotherapy on the biochemical beha vior of Trypanosoma cruzi strains, three groups of mice were infected with one of three strains of T. cruzi of different biological and isoenzymic patterns (Peruvian, 21 SF and Colombian strains). Each group was subdivided into subgroups: 1 - treated with nifurtimox; 2 - treated with benznidazole and 3 - untreated infected controls. At the end of treatment, that lasted for 90 days, xenodiagnosis, sub inoculation of blood into new born mice and haemoculture were performed as tests of cure. From the positive tests, 22 samples of T. cruzi were isolated from all subgroups. Electrophoretic analysis of the isoenzymes PGM, GP1, ALAT and AS AT failed to show any difference between parasite strains isolated from treated and untreated mice, which indicates that no detectable clonal selection or parasite genetic markers alterations concerning the isoenzymes analysed have been determined by treatment with drugs of recognized antiparasitic effect, suggesting stability of the phenotypic characteristics of the three biological types of T. cruzi strains.
