Abstract
The article presents long-term data on the study of the productivity of cotton varieties and lines in the conditions of Central Tajikistan. In all samples, the number of boxes ranged from 12.6 to 20.4 pcs/plant. This indicator varies along the lines in the range of 9.4–21.8 pcs/plant, which is significantly higher than the standard variety Ziroatkor 64 (9.4 pcs/plant) — up to 12.4 pcs/plant. With a maximum value (17.0–20.4 pcs/plant) of this feature, the varieties Farovon 20, Dusti IZ, Yage 110 and Dangara 30 distinguished themselves with a deviation from the standard by 7.6–11.0 pcs /plant. The weight of one box of varieties of Turkish (foreign) breeding NAK-99/1 is 6.2 g, DP—5111 — 6.0 g, local varieties Kabadian 30 — 6.7 g, Yage 110 — 6.2 g, Farovon 20 — 6.1 g, which is higher than the standard variety Ziroatkor 64 (5.0 g) by 1.7 g, and according to the best foreign — up to 0.6 g. The best indicators of the economic harvest from among the studied varieties and lines of medium-fiber cotton were varieties of local selection Kabadian 30 (65.6 c/ha), Dangara 30 (54.5 c/ha) and Yage 110 (51.2 c/ha), and from foreign ones — DP-5111 (57.2 c/ha), which exceeded the standard Ziroatkor 64 (39.0 c/ha) to 26.6 c/ha, and of the promising lines — L-1 (79.0 c/ha), L-4 (76.1 c/ha), L-7 (70.1 c/ha) and L-2 (69.7 c/ha). The deviation from the Ziroatkor 64 variety (39.0 c/ha) ranged from 30.7 to 40.0 c/ha, and from the best foreign variety — 12.5–21.8 c/ha.
