Abstract :
The present research was done (2016-2017) in order to investigate the comparison of wheat cultivars regarding yield and yield component in alborz, Qazvin. These cultivars included: Pishgam, Heydari, Parsi, Sivand and c-91-4 that analyzed as Randomized Complete Block Design in 3 replications. Analysis of variance showed that cultivars had significant effect on grain yield at 1% level. The results of the comparison of the cultivars showed that Pishgam with the average of 6035 kg.ha-1 had the highest grain yield, which was statistically classified in a common group with a C-91-4 (average 5630 kg.ha-1). Mihan with the average of 4400 kg.ha-1 had the lowest grain yield that was in a same group statistically with Parsi, Heydari and Sivand cultivars. The reasons for the superiority of grain yield in Pishgam cultivar are due to the higher number of seeds per spike and the number of spikes per unit area. Analysis of variance showed that the cultivar had a significant effect on biological yield at 1% level. The results showed that Sivand cultivar had the highest biological yield with 28110 kg / ha. The lowest biological yield was observed in Pishgam and Heidari cultivars.
