Abstract
In order to evaluate of yield and yield components of eight wheat cultivars against flix weed (Descurainia Sophia), an experiment was conducted using a factorial arrangement of treatments in a randomized complete block design with four replications during 2003-2004 growing season in Varamin region. The wheat cultivars were Tabasi, Roshan, Karaj2, Azadi, Niknejad, Mahdavi, Shiraz and Pishtaz. In this experiment traits such as: competitive index, grain yield and yield components of wheat were measured. The results showed that significant differences between cultivars in yield, so results of analysis of variation showed cultivars were significant differences in (HI), but were not significant differences between cultivars under weed-infested and weed-pure condition. The results showed that cultivar Niknejad from the competition ability was superior to cultivars and had a greater yield compare to other cultivars.
Key words: Competitive index, Niknejad, AWC
