Abstract
A genetic option for increasing wheat production is to reduce menace of weeds through developing
or screening weed tolerant wheat genotypes. To screen bread wheat genotypes tolerant to weeds in
dryland conditions, twenty six genotypes and two checks were evaluated in weed-free and weedinfested
plots using a strip-plot experiment in 2002-03 at Dryland Agricultural Research Institute
Srarood- Kermanshah, Iran. Labeling the genotypes as G1,… ,G28, the top five genotypes for grain
yield in presence of weeds were G15, G8, G26, G2 and G13. Genotypes G13, G26, G2 and G4 were
found most tolerant to weed-interference. However, using the competition index, the genotypes
within top 5 for yield under weed-interference were G13 and G2. The clustering of the genotypes
using the tolerance and competition indices resulted into three clusters each giving a different level
of tolerance and yield. Considering the tolerance, competition and high yield, genotypes G13, G26
and G8 were found most suitable for introduction in breeding program
