Sažetak
Seed size (frequently measured as volume) is an important component of seed quality that has been studied extensively for many crop species. The positive influence of seed size on grain yield of cereal crops is mainly well known. On the other hand, the effect of seed size on yield components and important factors of seed quality has not been reported to the same degree. The objectives of this study were to evaluate the relative influence of seed size of three spring malting barley cultivars (Hordeum vulgare L.) on grain yield, yield components and certain seed quality factors important in malt industry and to determine the correlation among yield and its components. Research was conducted at Maksimir experimental field, Zagreb, Croatia. Seed size positively affected most of the studied traits. Grater grain yield, reduced grain moisture content at harvest, lower risk of reduced stand density, higher starch content and seed vigour are extremely important agronomic attributes associated with large seed. Cultivar Knin significantly exceeded other two cultivars (Tomislav and Trojanac) both in grain yield and seed quality. Mainstem length, 1000 kernel weight, kernel number and weight per spike have been positively correlated with grain yield. High positive correlation has been determined between mainstem length and spike production.
