pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...

Marker aided selection (MAS) can be used for monitoring the presence or absence of genes in breeding populations and can be combined with conventional breeding approaches. In this study, crosses between two high yielding cultivars, Neda and Nemat with local aromatic varieties Sang tarom and Tarom deylamani were made followed by phenotypic selection for desirable individual plants in F2 populati...

Identifying the complete-linked molecular markers with target gene and mapping its chromosome locus is an important goal in plant breeding for gene cloning and marker-aided selection. Due to complexity of the interactions, in most of the agronomic traits, especially the interaction between the grain yield and the environmental factors, classic methods do not function appropriately in improving ...

genetic markers are one of the advances which have occured in the genomics era. among genetic markers, molecular markers mainly because of their abundance, are the most widely used them. development of molecular markers has greatly altered genetics and plant breeding. genetic markers indicate the genetic differences between different organs or species. some studies which were conducted during t...

linked and/or gene-based molecular markers have been used widely in marker-assisted selection (mas) to differentiate resistant and susceptible genotypes. resistance to meloidogyne spp. in beta vulgaris l. is mediated by a single dominant gene (r6m-1). using allele-specific primers (asps), an snp marker harboring a single nucleotide polymorphism (a/g), linked to the resistance gene was developed...

literatures have reported that a lot of drought related genes were cloned and individual gene showed positive effects under controlled stress experiments, but were not much effective in the field. although, the progresses by conventional breeding approaches were achievable as some drought varieties have been released to the farmers in the recent years but this is not adequate to cope up with th...

Polyploid breeding is an important means for creating elite willow cultivars, and therefore provokes an active demand for discriminating the ploidy levels of natural willow stands. In this study, we established an analytical toolkit for polyploid willow identification by combining molecular markers and flow cytometry (FCM). A total of 10 single-copy fully informative SSRs were chosen for marker...
