Assessment of genetic diversity among sunflower genotypes using microsatellite markers
Genetic diversity estimation of plant materials is one of the important pre-breeding activities in breeding field crops. Twenty-one microsatellite markers used to assess genetic diversity and relationship of 68 sunflower genotypes (Helianthus annuus L.). All of 21 pairs of SSR (Simple Sequence Repeats) markers produced a total number of 49 polymorphic bands. DNA fragments ranged from 9...
متن کاملGenetic Diversity Evaluation of Some Walnut (Juglans regia L.) Genotypes in Meshkin-Shahr by ISSR Marker
Genetic resources are the most valuable national treasure of countries, being vital to identify, conserve and use them. The Persian Walnut (Juglans regiaL.), a diploid species native to the mountainous regions of Central Asia, is the major walnut species cultivated for nut production and one of the most widespread tree nut species in the world. This research was conducted in M...
متن کاملevaluation of genetic diversity in some walnut (juglans regia l.) genotypes using morphological markers
identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. in order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in minoodasht region in golestan province (north of iran) were evaluated. traits such as nut shape, kernel color, ease of removal of kernel halves, ke...
متن کاملGenetic Diversity, Structure and Differentiation in Cultivated Walnut (Juglans regia L.)
An analysis of genetic structure and differentiation in cultivated walnut (Juglans regia) using 15 microsatellite loci revealed a considerable amount of genetic variation with a mild genetic structure indicating five genetic groups corresponding to the centers of diversity within the home range of walnut in Eurasia. Despite the narrow genetic differentiation among groups accounting for only 10 ...
متن کاملEvaluation of genetic variability among “Early Mature” Juglans regia using microsatellite markers and morphological traits
Limiting the juvenile phase and reducing tree size are the two main challenges for breeders to improve most fruit crops. Early maturation and dwarf cultivars have been reported for many fruit species. "Early mature" and low vigor walnut genotypes were found among seedlings of Persian walnut. Nine microsatellite markers were used to evaluate genetic diversity among "Early Mature" Persian walnut ...
