Abstract:
The efficiency with which nitrogen (N) is used by wheat and other cereals is gaining importance, because of increasing costs of N fertilizer and environmental contamination. Breeding of N efficient wheat depends, beside other factors, on the existence of genetic variation for N uptake efficiency. 20 local landraces of wheat were selected randomly from different rainfed regions of Mahabad and evaluated for nitrogen uptake efficiency as a randomized complete block design with four replications. Results showed a significant variation among local genotypes for nitrogen uptake. Genotypes numbered 2 and 14 had the highest N uptake efficiency. There was no significant interaction between nitrogen rate and genotypes; nonetheless highly efficient landraces could be involved in hybridization programs, advanced yield testing trials and may be released as superior cultivars after demonstration.
