in order to study of some effective phenologic and physiologic characteristics on 18 sunflower hybrids yield under optimum conditions, an experiment was conducted as randomized complete block design with three replications at the research field of seed and plant improvement institute-karaj in 2006-2007. the result indicated that the hybrids showed significant difference in phonologic characteri...

Correlation coefficient and path analysis studies was conducted with eight parents and their 28 F1 crosses for twelve component characters including seed yield and revealed significant positive association of pods per plant, harvest index and clusters per plant with seed yield in parental generation whereas in F1 generation, significant positive association of clusters per plant, pods per plant...

detopping in some plants reduces vegetative growth and increases transporting of photosynthate materials to specific sinks such as seeds. to study the effects of detopping removal and plant density on yield and yield components of faba bean (vicia faba l.), an experiment was carried out as a factorial arrangement based on a randomized complete block design with three replications at farm resear...

for different agronomic traits in sunflower (helianthus annuus l.) inbred lines were estimated using “line × tester” analysis method. six new restorer lines were crossed with four cms lines as tester in 2006 growing season. the 24 f1 single cross combinations were planted in complete randomized block design with four replications in khoy field research station in 2007 growing season. there were...

Combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. Parents and hybrids differed significantly for general combining ability (GCA) and specific combining ability (SCA) effects, respectively. The variance due to GCA and SCA showed that gene action was predominantly additive...
