Aim of study: Improvement of barley cultivars for malting traits suffers from narrow genetic pool in barley for these traits. Landraces are resources that could be used for this purpose. The present study was conducted to determine the variation for malting quality traits within a Turkish barley landrace. Area of study: The study was undertaken in Tokat, a province in Black Sea Region of Turkey. Material and methods: Twenty-five diverse lines, out of 42 unique genotypes previously identified in ‘Tokak’ landrace (PI 470281) based on DNA markers, were evaluated for malting quality traits along with the malting barley cv. ‘Tokak 157/37’ in four field trials. Thousand-seed weight, test weight, grain yield, lodging, malt extract percentage, diastatic power, alpha amylase and malt beta glucanase activities, malt protein and starch contents were determined. Main results: Principal component analysis of malting quality traits revealed that thousand-seed weight, alpha amylase activity, beta glucanase activity and diastatic power were the most discriminatory traits for the lines. As the average of four trials, 15 of the 25 lines evaluated had higher grain yields and 10 of 25 lines had higher malt extract percentages than the standard cultivar ‘Tokak 157/37’. Malt extract was highest in Line 59 in all environments, and this line also had the highest values for beta glucanase activity and starch content. Line 215 had highest values for alpha amylase activity. Lines 59 and 215 clearly had superior malting quality. Research highlights: These lines could harbor novel alleles for these traits to be used in malting barley improvement.
