bean root rot caused by plant pathogenic fungus, fusarium solani, is considered one of the most important diseases of bean in the world and in iran. because of economic importance of bean and the lack of information on population diversity of the pathogen in zanjan province, a research was conducted to study phenotypic, genotypic and pathogenicity variation of pathogen isolates and to assess pa...

Random regression models (RRM) are used for genetic estimations of milk traits in dairy cows. RRM utilize data on traits that are repeated during the time, such as milk trait, which allows of the evaluation of the test day production information. In this study, to estimate genetic parameters for milk production trait, test day records (TDR) were collected from the first lactation of Holstein co...

to determine the association between genetic parameters and traits in chickpea (cicer arietinum l.) genotypes, a field experiment was conducted with 17 chickpea genotypes using a randomized complete block design with four replications at the ilam agricultural and natural resources research center in the 2004 growing season. genetic parameters including genetic, environmental and phenotypic vari...

The objective of the current study was to estimate the genetic parameters for body weight traits at different ages in Iran-Black sheep. Data collected during a 24-year period (1984-2008) on body weight were used to model the growth trajectory and estimate genetic parameters. Studied traits were birth weight (BW), weaning weight at 3 months of age (WW), 6 months weight (6MW), 9 months weight (9M...

Data from 14 inbred lines and 14 linecross groups of Hereford cattle at the San Juan Basin Research Center, Hesperus, were used to evaluate expected and realized response in birth and weaning traits and postweaning traits in males and females over a 28-yr period. There were large differences in the means and variances of the performance traits among the inbreds and linecrosses, with the inbreds...

There are numerous reports in the literature of advancing trends in phenophases of plants, insects and birds attributed to rising temperature resulting from human-driven climate warming. One mechanism that enables a population to respond rapidly to changes in the environment is termed phenotypic plasticity. This plasticity grants a degree of flexibility to enable the timing of developmental sta...
