Identification of a sequence characterized amplified region (SCAR) marker linked to the Puccinia psidii resistance gene 1 (Ppr1) in Eucalyptus grandis
While random amplification of polymorphic DNA (RAPD) markers linked to disease resistance genes have been widely used in plant breeding programs, they generally lack reproducibility. To overcome this major disadvantage and other drawbacks, RAPD markers can be converted into sequence characterized amplified region (SCAR) markers, which are genetically defined loci amplified by polymerase chain reaction (PCR) using...

Evaluation of aerobic hybrid analysis of combining ability in three line hybrids in Rice (oryza sativa l.) under aerobic conditions
Information on the availability of genetic variability and mode of gene action are critically important for choosing effective breeding methods that result in appreciable improvement in performance under drought stress. An investigation in rice (Oryza sativa L.) was carried out subjecting six ‘lines’ and 15 ‘testers’ crossed in a Line x Tester mating design and the 90 hybrids along with 21...

Impact of cooperative society on fish farming comercialization in Lagos State, Nigeria
This study was carried out to determine the impact of cooperative society among the fish farmers in Lagos State. A multi stage purposive sampling techniques was used to select five Local Government areas notable for fish farming business. 30 fish farmers were selected from each of the Local Government areas for cooperative society and 30 farmers from non cooperative society having a total of 150 respondents each. A well...

An appraisal-analyze method for SWC function of forest in Simian Mountain, China
Soil erosion is one of the biggest environmental problems. It is urgently needed to understand soil and water conservation capacity of different plantation types so that the best plantation type can be determined. In Qinjiagou watershed of Simian Mountain, Chongqing City, 18 indices were selected from canopy layer, litter layer, soil layer and topography to evaluate the soil and water conservation capacities of four...
