Determination with correlation and path analysis of relationships between yield and yield components in alfalfa (Medicago Sativa L.) genotypes collected from the Bursa

This study was carried out Agricultural Application and Research Center of the Faculty of Agriculture of Bursa Uludağ University in 2018, the experiment with three replications using Randomized Complete Block Desing. As experimental material was used 307 different common alfalfa (Medicago sativa L.) genotypes from 14 different district collected and propagated as clonal, of Bursa in 2015. In the study, total dry matter yield, main stem length, main stem thickness, main steam number, leaf size, number of flowering days, dormancy rate, growth habit and number of cuts such as properties were examined and was made out determination with correlation and path analysis of relationships between yield and yield components.According to the research results; total dry matter yield 1,8-1600,2 g/plant, main stem length 31,94 -148,30 cm, main stem thickness 1,40 ve 6,95 cm, main steam number 8.0-171,3 pcs/plant, leaf size1,0-8,0, number of flowering days 177-269 days, dormancy rate 1,0-9,0, growth habit 1-5 and number of cuts 1-7 pcs/plant changed in alfalfa genotypes. As a result of correlation analysis, positive correlation between was determined total dry matter yield with main stem length (0.631**), main stem thickness (0,405**), main steam number (0,620**), leaf size (0,347**), dormancy rating (0,339**) and number of cut (0,625). As a result of path analysis, total dry matter yield was determined the highest directly affect main stem number (0,389) %61,29 with, and number of cut (0,332) % 50,29 with. Total dry matter yield was determined the highest indirectly affect leaf size (0,332) %13,15 with on main stem length.
