WP 4 Evaluation of performance traits and salinity tolerance in multilocation field trials

 

Lead-managed by Aberystwyth University, United Kingdom


The primary objective of WP4 is to expand the current growth area for miscanthus through the trialing of elite genotypes derived from recent breeding efforts over a range of differing sites across Europe. Elite genotypes are planted on multy location field plots across Europe and evaluated with regard to establishment, yield and quality, taking into consideration traits such as senescense, nutrient recycling and nurtrient- use efficiency.
Plot-based trials were established at six locations in Europe, Russia and Turkey with 15 types of Miscanthus. In spring 2013 the average biomass was 2.2 ± 0.7 tonnes ha-1, the highest being 13.3 ± 0.2 tonnes ha-1 at Adana. Growth measurements in the second growing season used the newly devised standardised protocols. The top genotype was an elite hybrid, OPM-8.The 36 novel natural Miscanthus germplasm types collected in China in 2012 were planted into a salinity tolerance trial in Dongying starting in 2013.

Experimental agronomy trials for establishment of of new Miscanthus in grassland could successfully be set up at Hohenheim University on a good  and a marginal grassland site by interplanting miscanthus in existing grasslands. Mixed mixed grass stands are under evaluation now in the second growing period.
Expected results of WP4 are the availability of genotypes for marginal site conditions, more resilient to climatic extremes and coping with quality standards for specific uses. Understanding gene by environment interactions will help to give guidance to growers and users of miscanthus to choose the very best genotype in a given environment.
