Genetic divergence among corn hybrids and combining ability for agronomic and bromatological traits of silage

Authors: E. Gralak, M.V. Faria, A.S.T. Figueiredo, D.A. Rizzardi, M. Neumann, M.C. Mendes, C.A. Scapim and S. Galbeiro

We assessed the impact of genetic divergence and the ability to combine corn hybrids used for the production of silage on the agronomic and bromatological traits of silage quality. We evaluated 18 corn hybrids used as genitors in a circulant diallel scheme in which each genitor hybrid participated in 9 hybrid combinations, and.. Read More»

Molecular characterization of wheat germplasm using microsatellite markers

Authors: S. Ijaz and I.A. Khan

We investigated the genetic diversity of 63 wheat genotypes, composed of 48 accessions and 15 varieties, using 56 polymorphic simple sequence repeat primers. One hundred and eighty-six loci were found, with a mean of 131.26 alleles per locus. Cluster analysis based on microsatellite allelic diversity discrimi­nated the accessions and varieties into di..

Relationship between progeny growth performance and molecular marker-based genetic distances in Eucommia ulmoides parental genotypes

Authors: Y. Li, Y.C. Wei, Z.Q. Li, S.H. Wang and L. Chang

Progeny performances, variations and combining abilities for growth traits were evaluated in a factorial mating design of Eucommia ulmoides. Three marker systems, sequence-related amplified polymorphism, amplified fragment length polymorphism, and inter-simple sequence repeat, were u.. Read More»

Analysis of genetic diversity and population structure of oil palm (Elaeis guineensis) from China and Malaysia based on species-specific simple sequence repeat markers

Authors: L.X. Zhou, Y. Xiao, W. Xia and Y.D. Yang

Genetic diversity and patterns of population structure of the 94 oil palm lines were investigated using species-specific simple sequence repeat (SSR) markers. We designed primers for 63 SSR loci based on their flanking sequences and conducted amplification in 94 oil palm DNA samples. The amplification result showed that a rela.. Read More»

Genetic diversity among Zygophyllum (Zygophyllaceae) populations based on RAPD analysis

Authors: I. Hammad and S.H. Qari

Zygophyllum species are succulent plants that are drought resistant and/or salt tolerant, growing under severe, dry climatic conditions. Despite their importance and abundance in the Mediterranean and Middle East regions, there is little information concerning molecular variations among species of this genus. Genetic diversity..

Molecular characterization of Ephedra species found in Pakistan

Authors: S. Ghafoor, M.M. Shah, H. Ahmad, Z.A. Swati, S.H. Shah, A. Pervez and U. Farooq

Ephedra, also known as “ma huang”, is a dioecious, drought- and frost-resistant, perennial, evergreen shrub with compelling medicinal value. The genus is represented by 42 species around the world, 9 of which were provisionally reported from Pakistan. Species of the genus have a controversial taxonomy due to their .. Read More»

Phylogenetic relationships among Saccharum clones in Pakistan revealed by RAPD markers

Authors: S. Nawaz, F.A. Khan, S. Tabasum, M. Zakria, A. Saeed and M.Z. Iqbal

Forty sugarcane genotypes (clones), including elite lines, commercial cultivars of Saccharum officinarum and S. barberi clones, were fingerprinted with 30 RAPD markers, using a PCR-based marker assay. The genetic distance for RAPD data was determined according to Nei, and relationships between accessions were graphed in a dend.. Read More»

Genetic studies of “noble cane” for identification and exploitation of genetic markers

Authors: S. Nawaz, F.A. Khan, S. Tabasum, M.Z. Iqbal and A. Saeed

Forty genotypes (clones) of sugarcane, including elite lines, commercial cultivars of Saccharum officinarum and clones of S. barberi were fingerprinted with 50 SSR markers using a PCR-based marker assay. Nei’s genetic distances for SSR data were determined and relationships between accessions were portrayed graphically i.. Read More»

Multiple Mantel tests and isolation-bydistance, taking into account long-term historical divergence

Authors: Mariana Pires de Campos Telles and José Alexandre Felizola Diniz-Filho

Mantel tests of matrix correspondence have been widely used in population genetics to examine microevolutionary processes, such as isolation-by-distance (IBD). We used partial and multiple Mantel tests to simultaneously test long-term historical effects and current divergence and equilibrium processes, such as IBD. We used the.. Read More»
