Disease tolerance More detailed information is given on page 6. Grey Leaf Spot (GLS) As part of a major variety screening programme undertaken in Europe by Barenbrug breeders, Amiata, Barprium and Barorlandohave been identified as being highly tolerant to the damaging disease Grey Leaf Spot (GLS), caused by Pyricularia grisea or P. oryzae(see Fig. 1). These three varieties are all bred by Barenbrug in France and are weartolerant diploid cultivars. Drechslera Leaf Spot DrechsleraLeaf Spot is a very common disease affecting stadium pitches in winter, proliferating in cool, damp and shaded conditions. Independent trials, including BSPB in UK and GEVES across several European countries, have highlightedBarprium and Barbastenas being particularly tolerant against this pathogen. Data is provided on page 7. Rhizoctonia Brown Patch A less common disease issue in the UK, Brown Patch can be a problem during a hot and humid renovation period. Internal Barenbrug trials have shownBarprium and Barorlandowill offer good protection against this disease. Top performing varieties Disease tolerance is only one aspect of ELITE DEFENCE. Crucially, the performance and wear tolerance of the five varieties in UK winter sports conditions is also very strong. Central to this is the utilisation of only European-bred diploid cultivars, which offer far better wear tolerance than tetraploid or American-bred grasses. Barzicoholds the coveted #1 position in BSPB Turfgrass Seed Table S1, trialled under winter sports wear simulation at 25mm height of cut. Barbastenis ranked #3 in the same trials. Both varieties are bred in Holland and have later heading characteristics, which make them exceptionally active in winter/spring recovery. Barorlandois itself a former #1 in BSPB trials, and performs very well in wear trials across Europe. Amiata and Barprium have both been trialled in the UK. AlthoughBarprium performs less well in Bingley, it topped internal Barenbrug trials at Cropvale in Worcestershire. Amiata returned above average scores in UK trials. Barorlando, Amiata and Barpriumoriginate in France, and are generally earlier in their heading dates. Five varieties, with diverse genetic backgrounds, provides excellent mixture synergy overall. Camera-friendly colour Another significant benefit of ELITE DEFENCE over other market options is a strong mid-green genetic colour. Barorlando, Amiata and Barpriumall offer benefits on this front, with impressive colour scores of 7.2, 6.3, and 7.0, respectively in BSPB S1 trials. Combined with their disease tolerance, this promises excellent visual aesthetics throughout the season for TV cameras.
