Abstract
This study aimed to compare 46 different lesser burnet (Sanguisorba minor) genotypes collected from nature in various cities of Turkey regarding yield and hay quality traits and to select superior and high-quality genotypes. For this purpose, lesser burnet genotypes were grown in 2018-2019 according to the randomized block design with 3 replications. In the study, the difference between the genotypes was statistically very significant in terms of all traits examined. (P ≤ 0.01). According to the obtained results, herbage yield varied between 3737 and 18,182 kg/ha, hay yield varied between 1713 and 5777 kg/ha, protein yield varied between 190 and 823 kg/ha, ADF varied between 29.08 and 39.89%, NDF varied between 33.96 and 55.81%, crude oil varied between 0.41 and 2.65%, crude ash varied between 5.56 and 14.41%, crude protein varied between 9.33 and 14.41%, condensed tannin varied between 1.08 and 4.11%, dry matter digestibility (DMD) varied between 58.01 and 66.41%, dry matter intake (DMI) varied between 2.15 and 3.55% and relative feed value (RFV) varied between 160.93 and 300.55. The study revealed that lesser burnet genotypes generally have higher mineral content compared to many other forage plants commonly used in animal nutrition. Furthermore, the GT biplot analysis, which explained 61.90% of the variation, was effective in genotype selection. The study suggests that many lesser burnet genotypes have the potential to be cultivated in field agriculture and could contribute to animal nutrition in the future due to their superior characteristics.
