Qoraqalpoq sur qoʻylarini rangbarangligi boʻyicha diff erensiyalangan juftlashda avlodlarda gul ko‘rsatkichlarining namoyon boʻlishi

Maqolada qoraqalpoq sur qoʻylarini rangbarangligi boʻyicha diff erensiyalangan juftlashda avlodlarda gul tiplarining namoyon boʻlish darajalari boʻyicha tadqiqot natijalari yoritilgan. Tadqiqotlarda ota-onalarni rangbarangligi bo‘yicha diff erensiyalangan juftlash natijasida har uchala guruh juftlashda yarim doira qalamgul tipli avlodlar chiqimida farqlanishlar kuzatilib, yuqori
ko‘rsatkich birinchi (60,0±6,32%) va ikkinchi (62,0±6,26%) variantlarda kuzatilib, uchinchi variantda ushbu ko‘rsatkichning nisbatan 6,7-8,7 foizga kamayishi aniqlangan (53,3±6,43%). Shuningdek, qoraqalpoq sur qoʻylarini rangbarangligi boʻyicha gomogen va geterogen juftlash natijasida 45,0-62,0% yarim doira qalamgulli, 13,3-20,0% qovurgʻasimon qalamgulli, 6,7-26,7% yassi qalam gulli avlodlar olish mumkinligi bayon qilingan.

The article presents the results of a study of the degree of manifestation of curl types in the off spring of diff erentiated crossing of the Karakul sheep breed Karakalpak Sur. The research revealed diff erences in the yield of off spring with a semicircular feather type in all three groups of crossings: a high indicator was noted in the fi rst (60.0 ± 6.32%) and second (62.0 ± 6.26%) variants, and a
relative decrease in this indicator by 6.7–8.7% in the third variant (53.3 ± 6.43%). It was also found that with homogeneous and heterogeneous crossing of Karakalpak Sur sheep by color, it is possible to obtain off spring with 45.0–62.0% semicircular, 13.3–20.0% ribbed and 6.7–26.7% flat.
