Determination of some agricultural characters in two row barley (Hordeum vulgare L.) genotypes obtained by hybridization and mutation

In this study, 20 advanced generation cross breed barley genotypes, 5 cultivars (İnce-04, Burakbey, Ünver, Larende and Tarm-92) and 5 mutant genotypes (selected from Cobalt-60 Gamma radiation treatment to Tarm-92 cultivar) were investigated in terms of some agricultural characteristics and quality in Isparta conditions. The research was carried out in the Field Crops experimental areas of the Faculty of Agriculture between 2019-2020, according to the randomized blocks trial design with 3 replications and 500 seeds were planted per square meter. With sowing, 6 kg of phosphorus (P2O5) and 5 kg of nitrogen (N) were applied per decare, and the rest of the nitrogen (5 kg/da) was given during tillering. Plant height, spike length, spikelet number per spike, grain number per spike, grain weight per spike, 1000 kernel weight, hectoliter weight, husk rate and protein ratio were examined in different genotypes, and the relationships between these characteristics were determined by correlation analysis. As a result of the research, the properties that can directly or indirectly affect the grain yield and quality (M-4 in spike length; M-14 in the number of spikelets; M-14 and M-15 in the number of grains per spike; M-4 and M-10 in grain weight per spike; M-20; M-4, M-10, M-15 and M-17 in hectoliter weight; G1, G2 and M-5 genotypes in protein ratio) were determined superior to control cultivars.
