Human-induced land use changes are causing extensive habitat fragmentation. As a result, many species are not able to shift their ranges in response to climate change and will likely need to adapt in situ to changing climate conditions. Consequently, a prudent strategy to maintain the ability of populations to adapt is to focus conservation efforts on areas where levels of intraspecific variati...
this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...
In order to study the genetic and environmental variability of morphological and phenological characteristics and also to gain a better understanding of the morphological basis of yield variation in soybean, an experiment was conducted at Research Farm, College of Agric., Isfahan University of Technology, in 1996. The experiment was arranged in three augmented designs with 285 lines and 5 contr...
the phenotypic diversity of potato, solanum tuberosum was assessed using morphological traits. to verify, how this diversity is distributed among the main potato varieties in the growing areas in iran. a total of eleven potato varieties, ramose, sante, shepody, marfona, maradona, milova, santana, boren, cosima, granola and agria, were evaluated under vivo and situ experimental conditions in isf...

When the morphological diversity of a clade of species is quantified as the among-species variance in morphology, that diversity is a joint consequence of the phylogenetic structure of the clade (i.e., temporal pattern of speciation events) and the rates of change in the morphological traits of interest. Extrinsic factors have previously been linked to variation in the rate of morphological cha...
