“…The positive and significant correlation coefficients (r-values) between grain yield and the yield components such as plant height, spike length, kernel number per spike, kernel weight per spike, spike number per m 2 and harvest index were 0.191**, 0.265**, 0.406**, 0.247**, 0.361**, and 0.474**, respectively. Similar results for grain yield and plant height in barley were reported by other studies (Bhutta et al, 2005;Kisana et al, 1999;Samarrai et al, 1987). Akdeniz et al (2004) observed positive and significant correlations between grain yield and yield compo-The indirect effects of yield components on grain yield on one another were generally positive with some exceptions.…”

This research sought to determine the correlations between grain yield and yield components and to measure the direct and indirect effects of yield components on grain yield in barley by using correlation coefficient and path analysis methods, respectively. This research was conducted with ten varieties of two-rowed barley under the ecological conditions of the coastal zone of northwest Turkey during the years 2003-2004. Agronomic traits such as grain yield, plant height, spike length, kernel number per spike, kernel weight per spike, spike number per m2, harvest index and 1000-kernel weight were determined. The data from two years were combined. Correlation analyses indicated that the grain yield was positively and significantly associated with all the yield components except 1000-kernel weight. The highest correlation coefficients were found between grain yield and kernel number per spike (r = +0.406), and between grain yield and harvest index (r = +0.474). Results of path analyses indicated that harvest index had the greatest direct effect (+0.7716) on grain yield followed by spike number per m2 (+0.3359) and kernel number per spike (+0.2081). Percentages of their direct effect were 71.97%, 48.47% and 28.22%, respectively. On the other hand, most of the indirect effects of yield components on grain yield were found to be significant and positive. Because of the significant effects of the harvest index, spike number per m2 and kernel number per spike on grain yield, they may be regarded as criteria for barley improvement and breeding programs.

“…Ebrahim et al (2015) also investigate the same result of correlation for quantitative traits of 20 genotype of barley germplasm. Similar results for grain yield and plant height in barley were reported by other studies (Kisana et al, 1999;Wisal et al, 2109;Arshad et al, 2019). It was observed that the total variation was 81.24% with the Eigen value of 0.99% (Table 3; Figure 1).…”

B arely is an important cereal crop and ranks around fourth in the world cereal production statistics following wheat, maize and rice (USDA-2008). It is estimated that annually over 133.85 million tones barley is produced worldwide. Barley is used as feed, food and for the brewing and distilling industries (Morris and Bryce, 2000). Barley is containing 80% carbohydrates which is an important source of energy. In the roman times, barley was the most popular food of providing a high energy, before going to the circus. The gladiators were fed on barley diet, so they were called "hordeari" from hordeium. Researchers also found that the amount of cholesterol in humans is decreased in blood serum due to the consistency of Abstract | Genetic diversity can be investigated through different methods such as morphological traits, biochemical (SDS PAGE) and molecular markers. The present work was conducted on the basis of morphological and biochemical characterization in order to estimate the genetic diversity among the barley landraces; to explore significant variation which can be used in breeding programs. For this purpose, 40 barley landraces were collected from Dir Lower and Swat, districts of KP, Pakistan. A total of 18 traits were recorded, 10 qualitative characters including spike density, awn barbs, glume awn, lemma type and awn color, length of the rechilla hairs, lemma color, auricle pigmentation, photoperiod sensitivity and stem pigmentation. Variation was observed in these qualitative traits through frequency distribution. In quantitative traits maximum variation was found for plant height ranging from 36cm to 50cm, days to flowering range from 130 to 133 days), while 100 seed weight ranged from 36 to 86 g and plant biomass range from 50 to 199.5 g per plant. SDS-PAGE analyses of total seed storage protein resulted in a total of 18 polymorphic bands. Total genetic diversity on the basis of total seed storage protein analysis was 17.5%. In Band, the 14 total genetic diversity was (0.60%) followed by Band 16 (0.58%) and Band 17 (0.55%). Similarly, Band 3 showed diversity, while Band 8, 4 and 5 indicated 0.45, 0.38 and 0.35%, respectively. A cluster dendrogram tree was constructed which was divided into two linkage and further divided into seven clusters. The variation was found among the clusters. The information obtained from the study is useful in planning further crop improvement.

Barley is a crucial cereal crop with a diverse genetic heritage that includes landraces-traditionally cultivated variants that have adapted to varying agro-climatic conditions over centuries. Preserving barley landraces in genebanks is of utmost importance for safeguarding genetic diversity and aiding future breeding endeavors.This study aims an agro-morphological characterization of a selected collection of two row barley landraces conserved in the Osman Tosun Genebank. A total of 262 barley accessions were assessed in controlled field conditions to analyze various agro-morphological traits. The study unveiled notable disparities in the morphological traits of the genotypes, specifically in flag leaf anthocyanin, flag leaf sheath wax, spike shape, spike density, lemma color, grain color, lodging tendency, days to 50% flowering, plant height, spike length, spikelet quantity, and thousand grain weight, among other critical agronomical characteristics. To scrutinize the morphological disparities, the research utilized principal component analysis and ascertained that nearly 77.22% of the overall variance was accounted for by the first two principal components. The first four principal components accounted for 90.96% of the total variation, thus indicating significant genetic diversity among genotypes. The results of the cluster analysis revealed the presence of diverse genetic resources within the collection, with distinct groups of genotypes exhibiting similar traits being identified. The results of the agro-morphological characterization are a valuable resource for researchers and breeders, aiding them in making informed decisions regarding the management and application of barley landraces in breeding programs.
