In order to assess the relationship of grain yield and some of the agronomic traits recombinant inbred lines (RIL) population of bread wheat derived from the Roshan × Sabalan were used to detect the informative traits on grain yield as the suitable criteria for indirect selection and path coefficient analysis. Two hundred and sixty seven recombinant inbred lines with three control cultivars (Ro...

  An experiment was conducted to investigate the heterosis in 12 F1 hybrids of durum wheat using agronomic and morphological traits. Parents were selected according to the estimated genetic distances based on the results of a two-year field experiment, which were then crossed to produce F1 hybrids. Twenty-three genotypes (including 11 parents and 12 hybrids) were evaluated using a randomized co...

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...

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...

Two experiments were conducted under field and greenhouse conditions, to investigate the effect of herbal spraying chlormequat chloride (CCC) (0 and 2.5 g. L-1), soil incorporation of Zinc sulfate (Zn) at the three rates of 0, 25 and 50 kg ha-1, and pre-treatment of seeds with bio-fertilizer Nitroxin (Nit) in a randomized complete block design with a factorial arrangement and three replications...

A major source of photoassimilates deposited into the seeds is the closest photosynthetic source to the latter sinks. While the contribution made to grain yield by floral parts and the adjacent photosynthetic surfaces has been determined for a number of crop plants, such information lacks regarding safflower. Thus the present study was aimed at estimating the contribution of photosynthesis of s...
