Simplifying the selection procedure to improve yield of new genotypes of rice is necessary. in order to evaluate relationship among grain yield and other agronomic traits, an experiment was conducted in agricultural and natural resoures research center in 2015-2016 year. In present study, 10 rice genotypes were studied in randomized complete blocks design with three replications. Grain yield al...

to study and determine  effect of salinity on relationship between  agronomic  characteristics and grain yield, 167  of  the  seri/babax recombinant wheat inbred  lines (ril) together with two parents were evaluated using alpha latice design with two replications under two conditions (salt stress and normal), in zabol field station in 2011-12 cropping season. fourteen  traits  including: some a...

Fungal endophytes and their grass hosts have attracted growing research interest as systems in which to examine the ecological and evolutionary consequences of maternally inherited symbioses. The lion’s share of research for these endophytic symbioses has been focused on Neotyphodium endophytes in three introduced agronomic grasses (but especially one, tall fescue; see Faeth and Saikkonen 2007;...

Political responses to novel foods and crops can be specific to the new traits of those crops (agronomic versus enhanced nutrients), to the intended uses of those crops (food for people versus feed for animals), and also to the methods used to introduced those traits (conventional breeding versus genetic engineering). This article describes variations in observed political responses to three di...

BACKGROUND Combining ability effects are very effective genetic parameters in deciding the next phase of breeding programs. Although some breeding strategies on the basis of evaluating combining ability have been utilized extensively in hybrid breeding, little is known about the genetic basis of combining ability. Combining ability is a complex trait that is controlled by polygenes. With the ad...

Common bean ( L.) breeding programs aim to improve both agronomic and seed characteristics traits. However, the genetic architecture of the many traits that affect common bean production are not completely understood. Genome-wide association studies (GWAS) provide an experimental approach to identify genomic regions where important candidate genes are located. A panel of 280 modern bean genotyp...
