Abstract
Safflower is a crop native to Iran and could be improved in plant breeding programs by inter-specific crosses. This study was conducted to evaluate genotypes of safflower derived from interspecific hybridization for the relationships between some agronomic traits and yield components. The genotypes were planted according to a randomized complete block design with three replications at the research farm of Isfahan University of Technology in 2011. Seed yield per plant ranged from 41.6 to 49.14 gr. The hybrid genotype 4 (F6) had the highest mean of seed yield per plant. The results of the correlation analysis showed that 1000-seed weight and head diameter were the most correlated with the seed yield per plant. Stepwise regression results showed that the 1000-seed weight and head diameter were the most important factors determinants of grain yield per plant and justified 61 percent of yield variation. The path coefficients analysis also showed that, 1000-seed weight, head diameter and number of heads per plant were considered as the first order variables and accounted for 56% of total variation of yield. The results also indicated that both traits of 1000-seed weight and head diameter could be considered as selection criteria for increasing safflower yield in breeding programs.
