The effect of colchicine treatment of P. caeruleum on morphological and economically valuable traits, pollen size and fertility, and karyotype of also was studied. Colchicine treatment increased in the size of pollen by 13 % compared to the control, pollen fertility decreased by 19 %. Stained chromosomes of the karyotype were identified, their sizes were determined for the first time, and karyotype formulas for diploid K = (5m + 2sm + 2st) and tetraploid forms K = 2 (10m + 4sm + 4st) were compiled. As a result of colchicine treatment, the plant height decreased by 35 %, the stem thickness by 47 %, the number of generative shoots 18 %, the leaf length 23 % and width increased 22 %, compared to the control. The productivity of raw by 32 % and seeds of tetraploid plants exceeds diploid plants by 22 %.This research was supported government as signment (No. 0576-2019-0008).
