The biological material was represented by the lambs of the color varieties consolidated within the breed, respectively: black, grayish, brown, gray and pink. In order to obtain concrete results, the researches were performed on the generations of lambs resulting in lambing seasons from 2017, 2018 and 2019, respectively. The working method applied in the evaluation of the character represented by the size of the curl was the one presented in the official technical norms, specified in Section 1.4 and 1.5 of the MADR Order no. 22 / 20.01.2006. The data obtained were subjected to a statistical processing process using the computer program S.A.V.C. (Statistics Analysis of Variance and Covariance 2003). To test the statistical significance of the differences between the averages of the values of the studied parameters as well as the correlations between them, the algorithms Analysis of Variables (ANOVA Single Factor) and the Pirson Correlation were used. Given the fact that in the classic varieties, represented by black and grayish lambs, the average score is less than 7% compared to the maximum level that can be granted for this character, we can say that the improvement is in an advanced process. Among the colored varieties analyzed, the average score has a higher value in gray (23.11 ± 0.11), lower in pink (21.50 ± 0.50) and intermediate in brown (21.83 ± 0.19). Based on the results obtained, it can be stated that the improvement is in progress, and by directing reproduction and applying a sustained selection program, a shift in the desired direction of the expression of this character can be induced, with a direct beneficial effect on improving genetic structure.enCC BY-NC-SA 4.0https://creativecommons.org/licenses/by-nc-sa/4.0/pelts curl sizeimprovementsheepKarakul of BotosaniArticle
