Abstract

The objective of this study were to obtain information about genetic parameters of agronomic characters of sorghum populations derived from Single Seed Descent (SSD) method, and to estimate selection differensial and also to select of F4 population that have a high yield and medium plant height . The experiment was carried out at Leuwikopo Farm, Darmaga, Bogor from January to April 2014. The genetic material were F4 population derived from SSD. The results showed that based on the skewness and kurtosis values, all of the agronomy characters observed in this study were poligenic controlled and influenced by additive gene action. The genetic coefficient of variability values for all parameters varied from intermediate to high in F4 population. Agronomic characters in F4 responded positively to selection because of high broad sense heritability estimates. Correlation analysis showed that plant height, number of leaves, stem diameter, panicle length, panicle weight and 100 seed weight have significant and positive correlation to grain yield/plant. Differential value with selection intensity 10 % based on grain yield/plant will increase grain yield/plant 83.89 % and plant height 8.91 % in the next generation, whereas differensial value based on grain yield/plant and plant height will increase grain yield/plants 68.33 % and plant height 0.26 % in the next generation. It means that selected plant were expected increasing yield 83.89 % or 68.33 % in next generation.Keywords: heritability, cefficient genetic variability, correlation analysis, selection differential

Abstract

ABSTRACTPopulation Parameters of Tropical Mudflat Clam, (Anodontia edentula) in MangroveEcosystem. Over a 12 months period (Januari 2005 ? Desember 2005), population parameters oftropical mudflat clam, (Anodonta edentula) in mangrove ecosystem were determined. Theobjectives of this research were to study population parameters (growth, recruitment patternand mortality) of this tropical mudflat clam. The results showed that asymtotic length (Linfinity) of males, females, also males and females combined were 65.63 mm, 70.88mm and 70.58mm, and the size of males was less than females; annual growth coefficient (K) of males,females, also males and females combined were 1.3, 1.5 and 1.5 respectively, which indicateda fast growth of the clams in relatively short period, which were 2.3 years for the males, 2 yearsfor the females, and 2.1 year for males and females combined. Subsequently, total mortalityrate (Z) of the males, females, also males and females combined were 4.56 ± 0.31, 4.61 ± 0.65, and4.95 ± 0.43. These high rates were caused by the extreme life condition, also by the thin andfragile shells of the clams. Recruitment occurred every month in the males, females, and alsomales and females combined. Overall, there were two unequal pulses. The peaks of males werein June (12.38%) and October (14.77%), while in the females were in April (16.88%) and August(15.12%), and in the males and females combined were in March (12.67%) and May (20.26%).Keywords : Mudflat clam, growth, mortality, recruitment.Kata kunci: Kerang lumpur tropis, pertumbuhan, kematian, rekrutmen

Abstract

ABSTRACTThe use of resistant varieties is an appropriate alternative in controlling the late blight, a major diseases on potato, caused by the fungus Phytophthora infestans. The development of late blight resistant potato was done through hybridization between non-transgenic Atlantic or Granola with RB transgenic Katahdin SP904 and SP951. The hybrid clones which have been positively contained the RB gene were evaluated for the resistance to P. infestans in four Confined Field Trials (CFTs) i.e. Pasir Sarongge (2008), Lembang (2009-2010), Pangalengan (2010-2011) and Banjarnegara (2011-2012). There are twelve selected hybrid clones which were resistant to P. infestans both in each location of CFT or in four locations were obtained. These clones consist of five clones from crosses of Atlantic and trangenic Katahdin SP951 (B35, B169, B163, B11, B162) and seven clones from crosses of Granola and transgenic Katahdin SP951 (D76, D12, D25, D48, D38, D37, D15). The selected hybrid clones showed resistance to P. infestans until 14 to 18 days after infection or about 40 to 45 days after planting, in the absence of fungicide spraying. The hybrid clones had a resistance score varied from 7,65 to 8,23 and were significantly different from the parents Atlantic and Granola, with a resistance score of 3,6 and 3,45, respectively. This was also supported by AUDPC values, which showed that AUDPC of the hybrid clones were in the range between Atlantic or Granola and transgewnic Katahdin SP951. This indicate that the resistance level of the hybrid clones is in the range between susceptible and resistant check. The resistant hybrid clones are valuable genetic resources for late blight resistance breeding programs, particularly in reducing  the frequency of fungicide applications. Keywords : transgenic potato, hybrid clones, Phytophthora infestans, confined field trial

Abstract

ABSTRACTCarbondioxide (CO2) Absorption by Trees in "Mekar Sari" Fruit Garden, Bogor, in Relationto Green house Gases Mitigation. Biological diversity can make a significant contribution toreducing the build-up of greenhouse gases in the atmosphere. A biological diverse tropicalforest with a diverse plant species typically stores 50 times more carbon per unit area comparedto monoculture plantation replacing it. Thus, the trees in forests have an essential role in thefunctioning of the terrestrial biosphere, especially in the carbon cycle. Yet wild tree photosynthesesare poorly studied than crop photosynthesis for several reasons: the large number ofspecies; difficulty in measuring photosynthesis of entire trees or of forest stands. This researchaims to assess the contribution of biological diversity in CO2 absorption by analyzing thephysiological characteristics (photosynthesis, transpiration, stomatal conductance, leaf chlorophyllcontent) of tree species in "Mekar Sari" fruit garden, Bogor. The results will provideinformation on carbon sequestration of some tree species suitable for revegetation. Variance inCO2 assimilation rate is large among trees species. The results showed that there was a widerange of variation of CO2 assimilation rate between tree species. The overall CO2 assimilationrate ranged 2.33 - 13.42 ?molm-2s-1. The highest was Matoa (13.42 molm-2s-1 ) , followed byKacapi (12.50 ?molm-2s-1), Durian (11.00 ?molm-2s-1) and Nangka (11.00 ?molm-2s-1). Transpirationrate was recorded between 4.29 - 9.50 molm-2s-1. The rate of CO2 assimilation wasaffected by incident radiation and thus the quantum leaf (Q leaf) as well as leaf chlorophyllcontent. Correlation between CO2 assimilation and Q leaf under certain environmental conditionwas considerably high. Variance in stomatal conductance and transpiration rate variedamong tree species and were related to light intensity.Key words: Photosynthesis, CO2 absorption, trees

Abstract

ABSTRACTKarawang District is the largest producer of frog meat in West Java. To find out how the frog harvesting impacts to the represent condition of population in the wild, on 16-27 May 2016 population survey was conducted on paddy field in East Karawang by implementing transect method with total length was 3000 meters. The results of this transect method showed that the population of juvenile was the highest in most areas of transects, followed by pre-adult population. The population of adult individuals was at the lowest and most adult male individuals were detected by the call that they make. Conditions of water supply in rice fields also determine the conditions of juvenile and pre-adult populations; newly planted rice fields with high water availability obtained the highest population per unit area compared to the condition of paddy fields with a little water availability; but exceptions to the plowed rice fields, despite the availability of a lot of water but disturbance from human activities was also high. Average density per unit area m2 for a little watery rice fields to dry with a total length of 1500 meters transect were as follows: (1) juvenil density was 0.33 individuals/m2, (2) pre-adult density was 0.04 individuals/m2, (3) adult density was 0.005 individuals/m2. Average density for much watery rice fields with a total length of 1200 meters transect were as follows: (1) juvenile density was 0.89 individuals/m2, (2) pre-adult density was 0.08 individuals/m2, (3) adult density was 0.01 individuals/m2.Key words: population density, Fejervarya cancrivora, paddy field, Karawang District
