Analysis of Morphological Trait and Yield Components of Mutant Wheat under Different Levels of Nitrogen
Year: 2009
Type: article
Abstract: In order to evaluate the reaction of yield and yield components of wheat's mutant lines to different levels of nitrogen in the crop year of 2006-2007, an experiment was conducted as factorial based on completely randomized block design in 4 replicates in the Research Farm of Agricultural, Medical and Industrial Research School in Zaferaniyeh-Karaj-Iran the first factor included 5 genotypes of wheat (Tabasi-the maternal entity, T-65-7-1, T-65-5-1, T-6-67-60, T-65-58-8) and the second factor consisted of 4 levels of nitrogen (100, 140, 180 and 220 kg ha(-1) urea 46%). The result showed that grain's yield harvest index, number of grain/spike in mutant lines and their parent had significant difference (p < 0.01) in mutant genotypes, meanwhile, the biological yield and the number of spike m2 were not significant difference (p < 0.05). The harvest index, number of grains per spike, grain's yield, biologic yield and number of spikes m(-2), weight of 1000 grains didn't affected by applying different levels of nitrogen fertilizer.
