Selection of Spring Barley Lines Using Biplot Analysis for Yield and Quality Traits
Abstract
The method of observation and measurement is quite important for selection and affects the success of breeders. In order to develop high-quality and productive varieties, 20 barley lines were compared with 5 standard varieties in two growing seasons, and their performances were investigated. The research was carried out according to the Randomized Complete Block Design (RCBD). The research focused on grain yield and some quality parameters. According to the variance analysis results, year, genotype, and year*genotype interaction were found to be significant (p< 0.01; p< 0.05) in terms of yield. According to the average results of both years in the research, grain yield of genotypes varied between 4400-6800 kg/ha, hectoliter weight between 67.4-74.1 kg/hl, thousand grain weight between 35.7-49.7 g, protein ratio between 12.4-15.5%. In addition, genotypes evaluated with the GT biplot technique, and superior ones were determined. In the GT (Genotype x Trait) biplot technique, PC1 accounted for 46.35% of the variation, PC2 accounted for 34.40% and 80.7% of the total variation. According to the research results, depending on the ecological factors of the growing seasons, the grain yield and protein content in the first year (6680 kg/ha, 14.9%) were higher than the second year (5030 kg ha_1, 12.9%), on the contrary, thousand grain weight and hectoliter weight were higher in the second year (72.2 kg hl-1, 43.9 g) than the first year (69.7 kg/hl, 42.5 g). Determination of variety candidates by evaluating the results obtained from the studies carried out in different growing seasons with different analysis models in selection facilitates the work of breeders. As a result, while the lines 2,4,9,12,14,17,19,21,22, and 24 were selected and taken to the next generation, it was determined that the Kendal variety used as the standard in the trial showed high performance according to the average data of both years. In the breeding process, it is recommended that the variety candidates be evaluated with varying models of analysis, and the lines showing high performance according to the standards used as varieties in the trial be taken to the next generation in selection.
