Height of plant at maturity, measured from ground to the top of the spike. excluding awns

Counted as days from sowing to 50% of plants in flower. However, when planting in dry soils, in drland areas, it is counted from the first day of rainfall or irrigation which is sufficient for germination

See Figure 1, a visual measure of the density of a spike, measured on 1-9 scale. (spike density is not the same as spike shape)

observed on the outer glume

Measured on the outer side of sterile glume

The average number of spikelets per spike from five typical spikes selected from the growing accession.

The average number of seeds per spikelet, obtained from the central portion of the spike - using the five typical spikes coded in 4.2.6

If the is difficult to decide then the sodium hydroxide test can be used. Place grains in the petri-dish and add 25 ml of 5% solution NaOH for 60-90 minutes. Original red grains will be dark brownish orange. and white grains will be straw yellow.

See Figure 2.

Glass-like appearance. When seeds are transversely sectioned

Appearance during tillering, but before jointing

Subjective assessment of the tillers number per plant at low densities

Extent to which long days hasten flowering

Tendency of grains to sprout in the ear as a result of high moisture near to the harvest, recorded on 1-9 scale

Appearance of dry seeds after harvest

Measured as percentage of dry weight, (seed moisture equal to or less than 12%). Indicate the conversion factor used either N x 6.25 or N x 5.6

Percentage of lysine per per unit protein (absolute)
