Аннотация

In order to select the source material for breeding to breed a high-yielding variety adapted to the conditions of Northern Kazakhstan, the article presents the results of studying the source material of the collection of oilseed flax. The work was carried out according to generally accepted methods. The object of the study was collectible samples of oilseed flax of various ecological and geographical origin. Field work was carried out in 2020-2021 at the scientific and field station of the SPCGF named after A. I. Barayev, located in the Akmola region of Northern Kazakhstan. The studies studied the height of the plant, the number of boxes on the plant, the number of seeds in the box, the number of seeds from one plant, the weight of 1000 kernels and yield. The main evaluation measures of oilseed flax were: vegetation period – 3 varieties are allocated here (Kostanaiski yantar– St, Scorpio, Taurus); plant height – 1 variety (Agate); weight of 1000 kernels – Northern (8.0 g) and Sokol (8.1 g) number of boxes and seeds per plant – Nebesny (38 boxes, 225 seeds), Sokol (31 boxes, 143 seeds) and Bison (31 boxes, 140 seeds). Of the studied varieties, the most seeds from one plant had the varieties Sokol (1.18 g), Nebesny (1.74 g) and Northern (1.30 g). Kostanay (13.46 c/ha) and Rucheyok (11.31 c/ha) were the most productive.
