to investigate the yield and agronomic traits of winter bread wheat genotypes in irrigating condition and also to determine the relationship of these traits with grain yield, 15 advanced genotypes of wheat along with three conventional cultivars where studied using randomized complete block design in three replications in 2010 growing season at kheyr-abad agricultural research station. the anal...

In order to study of variability, relationship among traits, direct and indirect effects of traits influencing grain yield, 18 lines and cultivars of bread wheat were evaluated in a randomized complete block design with four replications during 2009-2012 cropping seasons. Coefficients of genotypic and phenotypic variability showed that lines had high genetic variation for peduncle length, grain...

abstractbackground and objectives: all changes in the development stages of plants results in the change of one or more yield components and finally, the ultimate yield and manipulation of these periods means to create new possibilities for increasing yield. accordingly, planting date has a significant impact on plant growth and development during the growth season, so that any shift in plantin...

Soybean is the promising oilseed in the face of protein and oil shortage. In this study 16 advanced soybean genotypes, in terms of seed yield and yield components were evaluated using multivariate statistical methods. This experiment was carried out in the form of randomized complete block design (RCBD) in the research farm of Ardabil Agricultural and Natural Resources Research Center (Moghan...
