1 Avalon x Cadenza DH population was grown in the field : Grown as Hege 80 drilled plots (1m x 5m) and Hege 90 drilled plots (1m 2 ) Traits scored on 3 replications of 204 lines plus parents in the field were :-ear emergence height yield lodging erectness 10 specimen tillers were also taken per plot before harvest : Traits being scored are:- Total weight of tiller biomass Number of spikelets Weight of seed 100 grain weight Hege 80 plots : Scored by Liz Sayers (JIC)

2 Traits scored on single plot on 204 lines plus parents in the field were :- ear emergence height yield Hege 90 plots Additional tillers were taken for stem thickness study: Scored by Simon Orford : Scored by Liz Sayers (JIC)

3 Phylochron Leaf emergence and growth stage development Canopy Winter habit (prostrate, semi-erect, erect) Tiller numbers (winter only) Stem extension and canopy expansion / growth rates Inter-leaf distances Leaf size (Length x Width and Area) Leaf posture Node heights and Internode Distance Peduncle length Peduncle extrusion...(height between flag leaf ligule and base of ear) Length of ear From these data values for date of Flag leaf emergence and interleaf distances/ leaf overlaps throughout the season can be compared for all lines at given growth/ development stages. Avalon x Cadenza - scored by Darren Lovell (RRes) on first 110 DH lines + parental lines Field based assessments at LARS 2002 and 2003

4 Avalon x Cadenza - Darren Lovell on first 110 DH lines + PLs Flowering dates Date to first flower on ten tagged plants... so 50% = 5 plants had already started flowering Septoria tritici incidence and severity on leaf 2 and the flag leaf Septoria tritici and S. nodorum on ears Disease severity TGW's Field based assessments at LARS 2002 and 2003

5 Avalon x Cadenza DH mapping population – glasshouse pathology tests at RRes Cereal viruses Mapping of the Sbm1 locus, conferring resistance to Soil-borne cereal mosaic virus, to the gene-rich region on wheat chromosome 5DL Genome (2006) in press Kostya Kanyuka (RRes) Septoria leaf blotch Screening using the sequenced strain IPO323 Jason Rudd (RRes)

6 Avalon x Cadenza DH mapping population – seed bulk up at RRes 204 DH lines in unreplicated plots 2005/6 season in preparation for the two years of replicated trials on NUE and canopy diversity (2006-8) After a double break crop
