Research ArticleOpen accessIn the abstractDiscrimination Capacity of RAPD, ISSR and SSR Markers and of their Effectiveness in Establishing Genetic Relationship and Diversity among Egyptian and Saudi Wheat CultivarsSalah El-Din El-Assal, Ahmed GaberProblem statement: Yield crop cultivars and landraces are valuable sources of genetic variations that the knowledge and implication of these variations are critical in the plant breeding programs. our major objective of this study is investigating the discriminating capacity of RAPD, ISSR and SSR markers and of their effectiveness in establishing genetic relationship and diversity among Egyptian and Saudi wheat … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 9 Mar 2012 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Lines of Chickpea Against Fusarium Oxysporum f. sp. Ciceris WiltRosa Marina Arvayo-Ortiz, Martin Esqueda, Evelia Acedo-Felix et al.Problem statement: In Mexico, 70 and 20% of chickpea is produced in Sinaloa and Sonora, respectively. In Sonora wilting by Fusarium Oxysporum f. sp. Ciceris (FOC) causes losses of up to 60%, while in other parts of the world ranged from 12-15% annually. The aim of this study was to evaluate the resistance of new lines of chickpea obtained through … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 5 Mar 2012 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Genetic Diversity among Sugarcane Cultivars (Saccharum officinarum L.) using Simple Sequence Repeats MarkersAshutosh Pandey, Rupesh K. Mishra, Shashank Mishra et al.Problem statement: Increasing sugar productivity is the main concern of sugarcane (Saccharum officinarum L.) breeding programs. The complexity and size of the sugarcane genome is a major limitation in its genetic improvement. Characterization of sugarcane provides essential information of genetic diversity for breeders utilize for crop improvement. Approach and Results: The objective of this study was to evaluate the microsatellite … …OnLine Journal of Biological Sciences, Vol. 11, Issue 4 · 27 Jan 2012 · 7,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Polymorphism Exon 9-11 at the Leptin Gene Receptor in Breeder Hens of Mazandaran Native FowlsHossein Ali Abbasi, Shahabodin Gharavysi, Rohullah AbdullahpourProblem statement: Leptin a 16 kD protein synthesized by white adipose tissue and involved in regulation of feed intake, energy balance, fertility and immune function. In order to evaluate the leptin gene receptor polymorphism, we have used a Restriction Fragment Length Polymorphism (RFLP) method. Approach: Blood samples were collected from randomly chosen 100 native fowls breeding station of Mazandaran. The … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 17 Sep 2011 · 7,700 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantitative Trait Loci Analysis of Novel Fusarium Head Blight Resistance in Tokai 66Y. Yen, A.M. H. Ibrahim, S. Malla et al.Problem Statement: Identification of Quantitative Trait Loci (QTLs) in durable resistant genotype is important for marker-assisted breeding. The study was conducted to identify QTLs linked to FHB resistance in 'Tokai 66', a Japanese genotype. Approach: A cross was made between Tokai 66 and Jagalene and the single seed descend was used to advance the population. The F2:4 and F2:5 populations … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Statistical Procedures for Analysis of Genetic Diversity in Domestic Animal PopulationsM. R. Nassiry, A. Javanmard, Reza TohidiProblem statement: A wide range of studies for the assessment of genetic diversity in livestock breed were conducted using genetic distance. For high-accuracy and unbiased estimation sampling methods, criteria of choosing type of DNA markers, distance measurement strategies, cluster analysis will be important for any genetic diversity projects. Approach: Main objective of this short review is focusing on application statistical … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 7,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Bovine Calpastatin Gene in Nelore Cattle Using Polymerase Chain Reaction-Restricted Fragment Length PolymorphismsAlireza Majidi, Jothi Malar Panandam, Awis Qurni Sazili, Siti Shapor SirajProblem statement: In beef cattle production, of meat quality and carcass traits are important. Traditionally beef cattle breeding programs unfortunately are time consuming and also recording of carcass and growth traits need heavy cost, Approach: Marker Assisted Selection (MAS) should be utilized in beef herds, along with economically important phenotypic traits, for genetic progress to made with respect to improving … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 7,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponse of Root Properties to Tripartite Symbiosis between Lucerne (Medicago sativa L.), Rhizobia and Mycorrhiza Under Dry Organic Farming ConditionsM. R. Ardakani, G. Pietsch, A. Moghaddam et al.Problem statement: It is generally considered that root turnover is a major contributor to organic matter and mineral nutrient cycles in organic managed agroecosystems. Approach: This study designed to investigate whether microbial activity could affect on root properties of Lucerne in an organically managed field under dry weather conditions. The trial was laid out as a factorial experiment in the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneration of Five New Musa Hybrids With Resistance To Black Sigatoka and High YieldRicardo Hernández, Teresa Ramírez, Juan Carlos Noa-Carrazana et al.The ability to identify genetic variation is indispensable to effective management and use of genetic resources. This work is the first approach concerning to generation and genetic differentiation of new Musa hybrid lines obtained in INIVIT (Cuba), crossing Musa acuminata male diploid (AA) x female triploid (ABB), genotypes selected by their resistant character to pests and diseases.
