مقایسه عملکرد و اجزای عملکرد دانه در هشت رقم و لاین پیشرفته گندم آبی در منطقه سردسیر اردبیل

The aim of this experiment was study and comparison grain yield and its components on wheat lines and varieties. 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 in 2012-2013. The number of spike per m2, number of spikelets per spike, number of grains per spike, thousand grain weight and grain yield were studied. Analysis of variance showed that all traits were significantly affected by treatments. Mihan cultivar had the maximum number of spike per square meter. Maximum and minimum number of spikelets per spike, respectively, belonging to Mihan and Gasqugen, these varieties had highest and lowest number of grains per spike (42.67 and 28.67, respectively). Thousand grain weights in lines C-89-7 was the highest amount (52.10 g), while the lowest was belonged to lines C-89-6. 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.
