Evaluation of Some Barley (Hordeum vulgare L.) Genotypes and F1 Hybridges Under Controlled Conditions

Abstract

In this study, it was aimed to evaluate the F1 hybrids of different barley genotypes and to use the lines that showed superior performance in terms of the examined characteristics in cultivar development programs. The research was carried out under controlled conditions in the greenhouse environment of Dicle University, Faculty of Agriculture, Department of Field Crops in 2019. In the study, 4 parents and 6 F1 hybrids were used as plant material. Seeds were sown in pots filled with 5 kg of soil, with 4 plants in each pot. Each pot was accepted as replication and the experiment was established according to the "Random Plots Trial Design" with 3 replications. In the study, heading time (days), physiological maturity time (days), SPAD value (amount of chlorophyll), plant height (cm), length of a spike (cm), number of spikelets per spike (pieces), number of grains per spike (pieces) and grains per spike weight (g) properties were examined. As a result of the analysis of variance, it was determined that there was a statistically significant difference between genotypes in terms of all other characteristics except physiological mortality. In terms of average values ​​of hybrids and parents, it was determined that hybrids came to the fore in terms of the number of days to spike, physiological maturity period, plant height, spike length, and a number of spikelets per spike, and parents in terms of SPAD value, a number of grains per spike and grain weight per spike. As a result of the research, it has been concluded that the A6 hybrid, which shows superior performance compared to its parents, and the A1 and A5 hybrids, which seem to be promising lines, should be transferred to the next cultivar development stages to be evaluated within the scope of the breeding program and tested in different environments and conditions.
