بررسی عملکرد، اجزاء عملکرد و راندمان زراعی جذب نیتروژن در ارقام و لاین‌های گندم در استان آذربایجان غربی

Lead to continuing effects for increasing extensive of yield by means of advanced agronomic operations and selection of high yielding resistant genotypes. There fore, due to evaluation and determination of best effective traits in improvement of yield and grain quality of local populations of winter wheat, an experiment was carried out in Uremia Agricultural Research station, on 30 local populations of winter wheat that were collected from different cool place. Population was planted in complete randomized block design with three replications. The under study traits were, plant height, grain weight of basis plant, Biomass weight of whole plot, grain yield of whole plot, harvest index, length of spike, Number of kernel per spike, thousand kernel weight and weight of spike. The results of correlation analysis were showed that traits had positive correlation. The results of analysis of variance were showed that, there were high significant differences among traits. Too between agronomic nitrogen efficiency of grain weight of basis plant, length of spike, thousand kernel weights, and grain yield of whole plot. Harvest index and number of kernel per spike had positive correlation. The results of comparison of mean's traits were showed that populations of 80, 83, 32 had high rate for purposes of harvest index. Also, the results of comparison of mean's traits were showed that populations of Shahriyar and Zarin purpose of biomass weight of whole plot and populations of Shahriyar and Zarin had high rate for purposes of grain yield and also, populations of triticale, 85, 42 for purposes plant height showed for consumer fertilizer nitrogen. Also, the results of comparison of mean's traits were showed that population of Alvand, Shahriyar and triticaleh had high number of kernel per spike. Also populations Shahriyar, triticaleh Alvand and zarin high rate for lengh of spike for between population temperate region had special for its. Thousands kernel weight populations Alamot and Zarrin high rate to answer for has used fertilizer nitrogen. Also population Zarrin, Shariyar and triticaleh high weights of spike basis plant had. Agronomic nitrogen efficiency population Zarrin, Shahriyar had high rate.
