Variety description

10 August 2026

The plant belongs to industrial crops grown for textile fiber, as well as seeds for oil and feed production. The average yield of seed cotton is about 2993 kg/ha, the average plant height is 62.14 cm.

Morphologically, the variety is characterized by a pubescent structure, which provides relative resistance to sucking pests, such as tobacco thrips. The boll weight is about 6.51 g, the number of seeds per boll is about 29.46, and the weight of 100 seeds is about 8.82 g.

The variety shows tolerance to drought and soil salinity, although a high concentration of salts negatively affects seed germination and germination energy. Fiber quality indicators are considered promising for the textile industry.
