ارزیابی و مقایسه صفات زراعی و عملکرد دانه در ارقام و لاین‌های امیدبخش گندم در شرایط آبی

Evaluation and comparison of agronomic characteristics and grain yield on wheat lines and varieties were carried out an experiment in 2012-2013. The experiment were carried out a randomized complete block design with used four cultivars Gasqugen, Mihan, Urum and Zare and 4-lines C-89-6, C-89-7, C-89-15 and C-89-17 as experiment treatments on Three replicates. Phenological traits, days to heading, maturity and morphological traits, plant height, spike length, fertile tillers per plant, harvest index, biological yield and grain yield were studied. Analysis of variance showed that all traits except days to maturity and harvest index were significantly affected by treatments. Maximum and minimum days to heading were belonged to Gasqugen and C-89-15 line, respectively. The highest plant height, tiller number was obtained from Zare cultivar. Mihan cultivar with significant different than others cultivars and lines in terms of spike length, number of fertile tillers per plant and biomass was the superior variety. Among genotypes studied, the highest yield (10316.6 kg per ha) was obtained from Mihan variety and Zare cultivar were led to lowest grain yield.
