Count number of tillers while still in boxes, usually easier to accomplish 2-3 days after cutting back. Scale (1-9)

Expressed as a mean angle of the tillers from the vertical, in autumn of establishment year or before tiller elongation in the following spring (scale 1-9)

To be estimated by eye in the autumn

To be assessed on plants sown in the spring, not exposed to short day/or low temperature vernalisation

The time in the year following establishment when 50% of the spaced plants have reached inflorescence emergence. A plant has reached inflorescence emergence when the top floral of three inflorescence has emerged past the indertion of the flag leaf

scale 1-9

Eye estimates of number of inflorescence per plant at maturity

Conservation/aftermath

D.O.M.D assessed on conservation cut 6.1.8.. Expresses as units of D.O.M.D higher (+) or lower (-) than approporiate control

Assessed on seedlings growth in glasshouse prior to transplanting in the field as single plants. Data reported as for productivity

Assessed on swards, usually at the completion of yield estimation. Eye estimate of ground cover of sown species. Data reported by adjustment to control (see appendix I)

Record number of days after January 1 (=1) when each plant has reached inflorescence emergence. Expressed as number of days earlier (+) or later (-) than appropriate maturity-group control

Coefficient of variation expressed relative to approporiate control

Flag width measured at inflorescence emergence

Flag width measured at inflorescence emergence

Longest measured when culm is fully elongated

Estimate of inflorescence production on sward productivity trial at each seasonal and regrowth cut
