Rye TETRA KORTKAYA

TETRA KORTKAYA is a winter rye variety created in 1986 at the SIBNIIRS branch of the ICIG SB RAS using the method of experimental polyploidy. It represents a tetraploid form, which means doubling the number of chromosomes compared to diploid varieties. Thanks to this, the variety has increased productivity and disease resistance, making it particularly valuable for cultivation in the West Siberian and East Siberian regions.

Plants of the TETRA KORTKAYA variety have a shortened stem height ranging from 77 to 149 cm, which contributes to lodging resistance. The ear is prismatic, yellow in color, and of medium length; the grain varies from medium size to large and has a yellow-green hue. The maturity period is medium-late, and winter hardiness is at the level of the standard. Yield results from state variety trials range from 16.0 to 37.2 c/ha, with a maximum recorded yield reaching 57.1 c/ha.

The variety is characterized by high resistance to diseases and pests, which increases the reliability of its cultivation. To achieve optimal results, it is recommended to sow TETRA KORTKAYA in settled areas of Siberia on black fallow, and in forest-steppe areas on cereal fallow without summer plowing with soil rolling. These agronomic techniques contribute to better plant development and increased yield.
