in this investigation some chemical and morphological properties of dog rose fruit in 10 regions of north iran were measured. results showed significant difference between traits in studied regions. beta-carotene ranged between 0.05 – 0.323 (mg/g fw). total soluble carbohydrate varied from 5.9 – 23.3%. the highest content of total anthocyanin 23.7 and the lowest was 7.71(mg/l cyanidin-3-glucosi...

Genetic diversity of 12 lemon balm ecotypes was evaluated using agronomic traits as well as ISSR and RAPD markers. Results of analysis of variance showed high diversity among the studied ecotypes. Cluster analysis using UPGMA method grouped the ecotypes into three different groups based on the agronomic traits. Twelve ISSR primers created 106 polymorphic bands among the studied ecotypes. An ISS...

Kinnow (Citrus reticulata Blanco) mandarin is a superior fruit crop in Pakistan; however, it is characterized by high number of seeds which is disliked by consumers and the processing industry. The objective of this work was to document the morphological and genetic differences in selected seeded and seedless Kinnow strains from two different locations i.e., Citrus Research Institute Sargodha a...

introduction despite the fact that iran is one of the major chickpea (cicer arietinum l.) center of origins, limited information is available regarding chickpea genetic variation and diversity. genetic diversity information is crucial for the choice of proper parents to establish new breeding programs. chickpea germplasm is poor, suggesting the need for gaining enough knowledge of genetic diver...

Genetic diversity amongst 21 induced mutant clones tolerant to salinity along with one non-irradiated sensitive clone of banana (Musa acuminata cv. Dwarf Cavendish (AAA)) were studied using morphological and random amplified polymorphic DNA (RAPD) markers. Out of the 30 phenotypic indices screened, 23 were polymorph and two traits, leaf habit and blotches color, were differentiated by non-irrad...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

The fungus Cercospora beticola Sacc. is the one of the most important pathogens on the sugar beet. This plant pathogen causes cercospora leaf spot disease which is a serious economic problem for growers of this crop all over the world. Traditionally, the identification of C. beticola is based mainly on conidial characters and host association, but today molecular characterization is necessary f...

Molecular markers are used in plant science a variety of ways. The method molecular genome marking based on RAPD-PCR makes it possible to determine the genetic status populations and establish intrapopulation relationships. In this work, we studied polymorphism dandelion Taraxacum officionale using RAPD markers. Five random amplified polymorphic DNA (RAPD) were diversity relationship between tw...
