Descriptors
Category: MORPHOLOGY
7.1.3-Plant height
(7.1.3) At matutity, measured from the ground level to the top of spike excluding awns
7.1.5-Auricle pigmentation
(7.1.5) Color of auricles
7.2.11-Awn colour
(7.2.11) Colour of the awns
7.2.12-Length of rachilla hairs
(7.2.12) see figure 9
7.2.3-Row number/lateral florets
(7.2.3) Number of spikelet groups (triplets) per spike
7.2.4-Spike density
(7.2.4) Average length in millimeters of the spike internodes in five spikes
7.2.6-Lemma awn/hood
(7.2.6) Presence and type of awn - see figure 5
7.2.7-Lemma awn barbs
(7.2.7) Type of pilosity of the lemma - see figure 6
7.2.8-Glume and glume awn (outer glumes)
(7.2.8) see figure 7
7.3.1-Kernel covering
(7.3.1) Whether or not the lemma palea adhere to the caryopsis
7.3.3-Lemma colour
(7.3.3) Colour of the lemma
7.3.4-Grain (pericarp) colour
(7.3.4) Colour of the grain
7.3.6-1000-kernel weight (g)
(7.3.6) With the use of grain counter and scale. Converted from weighing a lot of 250 kernels or more. Even though this trait is environment dependent, most growouts will occur in favorable environments.
Category: PHENOLOGY
7.1.1-Growth class
(7.1.1) Seasonality
7.1.2-Growth habit
(7.1.2) Should be assessed visually from the attitude of the leaves and tillers. The angle formed by the outer leaves and the tillers with an imaginary axis should be used. Visual scoring of the angle formed by the leaves with an imaginary axis
7.2.2-Days to flowering
(7.2.2) From sowing to when 50% of plants have started flowering. However, in dryland areas when planting in dry soils, it is counted from the first day of rainfall or irrigation, which is sufficient for germination. (Highly dependant on temperature-photoperiod interations)
Category: QUALITY
8.1.1-Protein content (%)
(8.1.1) Measured as percentage of dry weight (seed moisture equal to or less than 12%). Indicating the conversion factors used as either N x 6.25 or N x 5.6. Percentage of protein in a malt flour.
