Abstract:

Development of genetic variation and exploitation of this variation to select desirable genotypes is an effective method in plant breeding. In present investigation 11superior varieties and lines of safflower which have been selected from last years selected as parents in crossing block. Land preparation has been down in October and fertilizer used according to N60 P2O540. Crosses have been made in first year and F1 hybrids planted in two rows with three m length and 30 cm row spacing and evaluated for some agronomic characters in second year. The results showed that there was cosiderable variation aming hybrids for agronomic characters. Generally, three hybrids 411 x 47, 386 x 44 and 411 x 44 showed suitable characteristics and maybe some superior lines selected from them in consecuntive years from segrigation populations.
