La Rocca

Genetic Potential and Phytosanitary Protection

The «La Rocca» alfalfa variety from the Austrian breeding house Saatbau is an intensive strain focused on achieving consistently high yields of forage and hay. The technical value of this material lies in its comprehensive resistance to major pathogens that limit the productivity of legumes in temperate climates.

Phytosanitary Profile

A major challenge in alfalfa cultivation is the susceptibility of root systems and foliage to fungal and bacterial infections. Saatbau’s breeding program focuses on a biological shield: the variety demonstrates high resistance to verticillium and fusarium wilt, which are common causes of stand thinning after the second or third year. Resistance to anthracnose and bacterial wilt maintains high stand density, providing the crop with a competitive advantage against weeds.

Morphological Features and Productivity

The plant height of «La Rocca» ranges from 70–90 cm. This optimized structure, combined with a high regrowth rate after each cut, makes this variety an effective tool for multi-cut systems. The plant architecture simplifies mowing and baling processes, minimizing losses during mechanical harvesting. Austrian genetics ensure not only biomass volume but also high forage digestibility, which is critical for dairy farming operations.

Practical Implementation

Utilizing planting material from Saatbau Linz eGen is justified for farms with intensive utilization cycles. The «La Rocca» variety displays excellent adaptability to various soil types, provided that standard agronomic practices are followed. High resistance to soil-borne pathogens helps reduce pesticide reliance, making forage production more economically efficient and sustainable.
