Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

| A number of recent empirical studies of traf-c measurements from a variety of working packet networks have convincingly demonstrated that actual network traac is self-similar or long-range dependent in nature (i.e., bursty over a wide range of time scales) { in sharp contrast to commonly made traac modeling assumptions. In this paper, we provide a plausible physical explanation for the occurr...

many of precision farming studies have shown a high plant-to-plant variability for many crops. this study was conducted to evaluate the plant-to-plant variability of three medicinal crops in comparison with corn as a long term commercial species. thus a field experiment was performed in 2009-2010 in ferdowsi university of mashhad, research farm. in this experiment plant morphological characters...

Ranunculus L. with about 600 species is the largest genus in the Ranunculaceae. Problems in the taxonomy of the genus are due to high variability and polymorphism among different individuals and populations of certain species. Morphological characters of nectar scale have been considered as valuable taxonomical characters in some perennial species in some groups (Praemorsa, Grumosa, Rhizomatosa...

In order to determine genetic variability among 33 isolates of Fusarium semitectum, morpho- logical and molecular studies were carried out. Isolates from different paddy fields in the north of Iran were separated from each other in four morphotype groups. The isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextrose agar (P...

One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...
