Abstract

In order to study Phenology evaluation and yield comparison of twenty five SUNFLOWER genotypes under environmental conditions of Shahroud Region, a fieldexperiment was carried out in Agricultural Research Center of Semnan province (Shahroud) during 2009 growing season. This research was carried out in the form of simple 5´5 latis design with two replications. In this experiment, 25 treatments including 24 new hybrid producted from different cross between CMS (Cytoplasmic Male Sterilitiy) and RN (Restore of Fertility) were compared along with hybrid cultivar Azargol (Control). In this research, morphological traits of SUNFLOWER were analyzed such as plant height, stem diameterand, capitul diameter also other characters as biomass (Plant dry weight), seed yield, HARVEST INDEX, 1000 grain weight and grain quality including oil and protein percentage and yield. The results indicated a significant effect of genotype on the majority of studied traits in 1% probability level. In the present research, hybrid RN-126×CMS-31.2 had the highest capitul diameter (19.12 cm) and seed yield equal to 4391.1 kg/ha. Azargol hybrid (Control) which is plantable recommended for all determined regions for SUNFLOWER cropping, produced 4255.18 kg/ha GRAIN YIELD and was set in one statistical group with bartar hybrid. Achievement of the maximum OIL YIELD (1928.31 kg/ha) of RN-125×CMS-31.2 hybrid can be attributed to predominancy of this genotype, in traits of HARVEST INDEX (35.17%) and 1000 seed weight (75.12 g) among SUNFLOWER hybrids. Azargol hybrid had 1720.33 kg/ha OIL YIELD and indicated 12% decreasment in comparison to bartar hybrid.
