rapd markers through an application of 23 decamer primers were employed for genetic diversity analysis of some sweet cherry cultivars. bands with good resolution and high repeatability were selected for evaluations. the 23 primers produced 188 bands, among which, 153 were polymorphic. cluster analysis of the cultivars was performed based on the presence (1) and absence (0) of the bands, using j...

almond is one of the most valuable horticultural nut crops in the world with iran being amongst the most important regions of its distribution. rapd markers were employed to evaluate the diversity levels and relationship among some 56 collected genotypes of the crop. through sixteen rapd primers a number of, 171 dna bands were produced, 168 of which were polymorphic. the samples which according...

Field crop landraces are valuable genetic sources. Twenty populations of Persian clover (Trifolium resupinatum L.) collected from different areas of Iran were used in this study. DNA extractions were carried out using minipreparation method with equal amount of leaves from 30 plants of each population. DNA samples from 20 clover populations were evaluated using semi-random (ISJ) markers. Ten pr...

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...

Genetic improvement of crop plants such as wheat, relies on genetic diversity.  In the current investigation, the genetic diversity of 99 wheat lines and 49 cultivars were assessed using 20 SSR primers. Out of the primers used, 19 were polymorphic among studied lines and cultivars and a total of 67 alleles were amplified. The number of alleles per locus ranged from 1 (Xgwm44) to 7 (Xgwm47), wit...

background: traditionally, morphological features of rhipicephalus (boophilus) annulatus from closely-related ticks have been considered for their identification and differentiation. however, it is difficult and requires expertise in order to accurately identify and differentiate engorged female ticks and some developmental stages such as larva and nymph from other similar ticks. hence, molecul...

rapd markers were employed to determine the diversity among 29 genotypes and cultivars of sour and duke cherry as well as a mahaleb tree genotype as an outgroup. a number of 100 random primers were examined for pcr reactions on the template dnas extracted from leaves, of which 17 primers produced polymorphic bands. these 17 selected rapd primers produced 233 bands, among which, 214 were polymor...

rapd markers were employed to assess the genetic diversity of 34 iranian wild edible asparagus (a. officinalis) genotypes as well as cv. mary washington and a. persicus. in total, 80 rapd primers were employed for pcr reactions, among which, 18 revealed reasonable polymorphism. the 18 primers produced 175 bands, of which, 160 were polymorphic (91.4% polymorphism). cluster analysis of the genoty...
