Abstract:

This study was conducted at the experimental fields of Eskişehir Transitional Zone Agricultural Research Institute in growing seasons of 2013 and 214 in order to determine the to relationships between seed yield and yield components of nine hulless barley lines and one registered hulless barley variety -Özen- in rainfall conditions. Flag leaf area, flag leaf staying green time, stem length, upper internode length, spike length, number of spikes per square meter, harvest index, grain yield per unit area, biological yield per square meter, grain number per spike, grain yield per spike, sterile spikelet number, fertile spikelet number, total spikelet number, thousand grain weight, hectoliter weight, protein ratio, 2.5 mm above sieve and relationships between emergence time and number of days to earing were examined. According to the correlation analysis results there was a positive and significant relationship between grain number per spike and grain yield per spike, hectoliter weight and number of days to spike. However, a negative and significant relationship was determined in terms of protein ratio (r =-0.743**). As a result of this study, important relationships were determined between grain yield and biological yield per square meter, number of ears per square meter and harvest index.
