Udder morphology traits were measured and subjectively assessed by the use of linear scores in ewes of Tsigai (T), Improved Walachian (IW) and Lacaune (LC) dairy breeds. Analysis of variance was conducted and correlations between udder measurements and linear scores were computed for individual examined breeds separately. Subjectively assessed linear scores for udder depth, cistern depth, teat position and teat size showed high correlations with actual measurements of the respective traits on udder in all examined breeds (rp = 0.65?0.80). Linear scores for cistern depth and teat position were highly correlated (rp = 0.84; 0.77 and 0.90 for T; IW and LC ewes), suggesting that they are nearly identical traits.
