RELATIONS BETWEEN SPIKE YIELD and FLAG LEAF AREA in SIX and TWO ROWED BARLEY

Abstract

This study was carried out in Eskişehir Osmangazi University Faculty of Agriculture research and trial field during the 2002-2004 production season. In this study, it was aimed to reveal the genotypic and environmental effects on leaf pattern in barley (Hordeum vulgare L.). The study, in which 45 six-row and 7 two-row barley genotypes were used, was established according to a randomized block design. Flag leaf area index and spike characters were determined in barley populations. According to the findings obtained; It was determined that the flag leaf area was affected by environmental conditions and the difference between genotypes was not statistically significant. Larger leaf areas of two-row barley were associated with higher grain weight per ear, while smaller leaf areas of six-row barley were associated with more spike character. As a result of the study, it was determined that there were significant differences in flag leaf area and spike characters depending on barley row varieties.
