Abstract :
This resarch was conduted to evaluate seed yield and yield components of 20 barley lines at Agricultural and Natural Resources Resarch Center of Tabriz, Iran uing a randomized complete block design (RCBD) with three replications. Analysis of variance showed that there were sigificant differece among lines under study for plant height, thousand kernel weight, number of grains per spike, grain yield, spike weight spikes per square meter and spike length. This shows that there gentic was variations for these traits among the lines studied. Mean comparisions of the traits showed that line EBYTC86-17 by having higher spike length, kernel per spike and 1000 kernel weight produced highest yield. This line can thus be regarded as suitable far thurther studies and recommend at to this area. It was also revealed that lines EBYTC86-5, EBYTC86-6 and EBYTC86-13 were low producers. Results of simple correlation coefficients among the traits showed that yield and yield components were highly correlated with kernel weight and kernels number per spike. Based on regression analysis, 37 percent of yield variation can be attributed to seed number per spike and 1000 kernel weight. Results also showed that for each unit increase in 1000 kernel weight and seed number per spike yield increased by 30 and 14 percent respectively. However, each unit increase in plant height decreased seed yield by percent.
