Brittle rachis is expressed as the number of average spike rachis fragments per spike generated after threshing; the two trials conducted were designated as RF2012 and RF2013. Threshability is expressed as the percentage of threshed seeds (the number of threshed seeds/total seeds×100); the two trials conducted were designated as FT2012 and FT2013.
