A. Observe the coverage of the main panicle by the bristles and estimate the bristle density
B. Comparative visual observation of the biomass of plants (length, width, number of leaves, number of tillers) 30 to 40 days after sowing. The maximum score is given to the plot that has plants with maximum biomass. The lowest score is assigned to the plot with the minimum biomass. Plots with biomass between these two extremes will be scored between the two extreme scores.
C. Observation of the presence or absence of bristel on the main panicle on few number of plant per plot
D. Observation of the morphology of the entry to score agronomic desirability of the variety of five plants representative of the variety
