Churayivna

Genetic Foundation of Resistance

The 'Churaivna' soybean variety, developed by ISHP Naan, is a result of targeted breeding for phytosanitary autonomy. The core technological value of this material lies in its high resistance to the key pathogenic complex that reduces soybean yields in Ukrainian conditions annually.

Phytopathological Profile

The integrated protection of the variety is based on genetically determined resistance to the following diseases:

• Peronosporosis (downy mildew): barrier immunity allows for reduced fungicide application during the active growth period.
• Septoria: the variety effectively suppresses fungal leaf damage, ensuring full-scale photosynthesis until physiological maturity.
• Fusarium: the root system exhibits high regeneration capacity and resistance to rot, which is critical when planting in soil that hasn't warmed up sufficiently.

Technological Parameters

With a vegetation period of 110–120 days, 'Churaivna' belongs to the mid-early maturity group. This timeframe provides an optimal balance between biomass accumulation and grain moisture release. In field conditions, the variety demonstrates stable plant architecture, facilitating harvesting without critical pod loss on the lower levels.

For agronomists, this variety serves as a cost-reduction tool: high natural resistance to diseases eliminates the need for additional fungicide treatments, directly improving production profitability while maintaining high grain quality.
