safflower is a crop native to iran and could be improved in plant breeding programs by inter-specific crosses. this study was conducted to evaluate genotypes of safflower derived from interspecific hybridization for the relationships between some agronomic traits and yield components. the genotypes were planted according to a randomized complete block design with three replications at the resea...

DNA markers have enormous potential to improve the efficiency and precision of conventional plant breeding via marker-assisted selection (MAS). The large number of quantitative trait loci (QTLs) mapping studies for diverse crops species have provided an abundance of DNA marker-trait associations. In this review, we present an overview of the advantages of MAS and its most widely used applicatio...

Selection in breeding programs can be done by using phenotypes (phenotypic selection), pedigree relationship (breeding value selection) or molecular markers (marker assisted selection or genomic selection). All these methods are based on truncation selection, focusing on the best performance of parents before mating. In this article we proposed an approach to breeding, named genomic mating, whi...

The goal of many forest tree breeding programs is to increase the quantity and quality of wood products from plantations. Due to their outcrossing breeding systems, long generation times and relatively short history of domestication, breeding populations of most forest trees closely resemble the wild state. Consequently, vast stores of genetic variation are available for selection. Because wood...

The usefulness of genomic selection (GS) for improvement complex traits has been demonstrated in plant and animal breeding. While fully adopted the livestock sector commercial breeding, implementation GS public-sector breeding programs lags. goal this review is to discuss advancements opportunities near-term long-term adoption programs. We also highlighted specific applications cultivar develop...

Background The efficiency of plant breeding depends mainly on two actions of the breeder: creation and subsequent identification of superior genotypes. In both actions, selection plays a fundamental role in the definition of crosses to be performed, with interest in creating new genotypes and identifying superior trees to be used commercially. The great attraction of molecular tools for plant b...

the study of genetic variation and phylogenetic relationships is essential for the efficient selection of superior plant material and conducting introgression breeding programs. in iran, despite the wide geographical distribution of grasses no report is available on the genetic diversity and relationships of cool season grass populations. in this study amplified fragment length polymorphism (af...

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 ...

Open access, freely available online " Some qualities nature carefully fi xes and transmits, but some, and those the fi ner, she exhales with the breath of the individual as too costly to perpetuate. But I notice also that they may become fi xed and permanent in any stock, by painting and repainting them on every individual, until at last nature adopts them and bakes them into her porcelain " —...
