Variety description

10 August 2026

The variety is day-neutral, possesses early formation of sympodial fruiting branches having a zigzag appearance, which contributes to the horizontal expansion of the bush. In comparative studies, the variety was classified as less early-maturing relative to later genotypes.

Fiber quality indicators include a fiber percentage of 35.9%, a fiber index of 10.5, a fiber length of 1.17 inches, and a strength of 19.75 g/tex. In studies of the response to water stress, a decrease in fiber yield was recorded due to short-term flooding. The variety was used in experiments to study the effect of growth regulators for plant height control.
