Evaluation 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 ...
متن کاملAssessment 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 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 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 کاملAssessment of the Genetic Diversity of Almond (Prunus dulcis) Using Microsatellite Markers and Morphological Traits
The genetic diversity among 56 almond (Prunus dulcis) genotypes was analysed using 35 microsatellite markers and 14 morphological traits. Analysis of morphological traits revealed a wide range of variation among the studied genotypes. Out of 35 simple sequence repeats (SSRs) markers, 25 were polymorphic, producing 215 alleles that varied from 2 to 16 with an average of 8.76 alleles per locus. R...
