Clearfield 1

Innovative Spring Rapeseed Selection from NULES of Ukraine

The «Klytynnyi 1» spring rapeseed variety, developed by the National University of Life and Environmental Sciences of Ukraine (NULES), represents a breakthrough in domestic breeding designed for intensive farming systems. This simple linear hybrid/variety stands out for its adaptability to diverse soil and climatic conditions, addressing the needs of modern farmers who prioritize both high yields and production efficiency.

Clearfield Technology and Disease Resistance

A key feature of «Klytynnyi 1» is its inherent resistance to imidazolinone herbicides (Clearfield system). This trait offers a significant advantage in crop management, enabling efficient weed control with a single herbicide application. By reducing the number of interventions, the variety helps farmers lower operational costs and ensures the crop develops without the stress typically caused by intensive weed competition.

The variety is specifically bred to withstand significant pressure from common fungal diseases, reducing the necessity for multiple fungicide applications. It displays strong resistance against:

• Phoma and Alternaria;
• Sclerotinia and various types of rot;
• Root rot and Black leg (Leptosphaeria maculans);
• Peronosporosis (downy mildew).

Production Traits

Morphologically, the plants reach a height of 150–160 cm and exhibit a medium branching pattern. The flowering period spans 30–40 days, facilitating uniform pod set and balanced maturation. Regarding quality parameters, «Klytynnyi 1» consistently yields seeds with an oil content ranging from 40% to 45%, meeting the requirements of both crushers and export markets.

Opting for «Klytynnyi 1» means investing in a proven Ukrainian breeding product that harmonizes modern agro-technology with biological resilience. It is an excellent choice for agricultural producers looking for a reliable, high-potential rapeseed variety capable of delivering consistent results in various field environments.
