This research was conducted to study relationships among yield and yield components in Orchard grass (Dactylis glomerata). For this purpose 25 half sib families derived from poly cross of 25 parental genotypes were evaluated under two moisture environments (normal and drought conditions) according to a randomized complete block design at the research farm of Isfahan University of Technology. Th...

Planting pattern through changing vegetative growth and utilization of environmental resourses affects yield components and seed yield. These effects were studied in the spring of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plot layout and three replications. Main plots consisted of three row distances (30 cm...

In order to evaluate relations between phonological trains , yield components and grain yield of 30 soybean lines with different maturity groups , an experiment conducted as a randomized complete block design with three replications at the agricultural research station of agriculture and natural resources research center, Gorgan, Golestan Province in 1388. 13 traits of vegetative and reproduct...

thirty-three M7 soybean mutant lines which originated by γ ray (co-60) from cultivar L17 irradiated with doses150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivars Clark (CL) and Williams (WI) were evaluated in view of some agronomical and morphological traits under completely randomized design with three replications. In M7 mutant lines all traits except number of s...

Breeding based on selection indices is an effective method for improving complex traits such as yield. To assess the efficiency of different selection method, 83 exotic along with 17 Iranian safflower genotypes were evaluated at the research farm of Isfahan University of Technology using 10×10 simple lattice design with three replications in 2011. In this study, the selection indices of Smith-H...
