Descriptors
Category: MORPHOLOGY
  1. 7.1.3-Plant height (7.1.3) At matutity, measured from the ground level to the top of spike excluding awns
  2. 7.1.5-Auricle pigmentation (7.1.5) Color of auricles
  3. 7.2.11-Awn colour (7.2.11) Colour of the awns
  4. 7.2.12-Length of rachilla hairs (7.2.12) see figure 9
  5. 7.2.3-Row number/lateral florets (7.2.3) Number of spikelet groups (triplets) per spike
  6. 7.2.4-Spike density (7.2.4) Average length in millimeters of the spike internodes in five spikes
  7. 7.2.6-Lemma awn/hood (7.2.6) Presence and type of awn - see figure 5
  8. 7.2.7-Lemma awn barbs (7.2.7) Type of pilosity of the lemma - see figure 6
  9. 7.2.8-Glume and glume awn (outer glumes) (7.2.8) see figure 7
  10. 7.3.1-Kernel covering (7.3.1) Whether or not the lemma palea adhere to the caryopsis
  11. 7.3.3-Lemma colour (7.3.3) Colour of the lemma
  12. 7.3.4-Grain (pericarp) colour (7.3.4) Colour of the grain
  13. 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
  1. 7.1.1-Growth class (7.1.1) Seasonality
  2. 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
  3. 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
  1. 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.


Banco Nacional de Germoplasma Vegetal Policy

The “Banco Português de Germoplasma Vegetal” (BPGV) conserves living seed and plant samples of mainly Portuguese crops and their wild relatives.

BPGV ensures that the genetic resources that support our food supply are both secure in the medium and long term for future generations and available for use by farmers, plant breeders, and researchers.

These collections are important to ensure that crop plants, which may contain genes to resist disease, provide enhanced nutrition, or survive in changing or harsh environments do not become endangered or extinct over time.

The BPGV located in Braga, Portugal maintains clonal and seed collections of the most important crops, such as cereals, grain legumes, vegetables, medicinal and aromatic plants, forage, pasture and fruit species.

The BPGV is maintained as a global public good under the FAO International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA).

BPGV is the custodian of one of the largest germplasm collections, with more than 10,000 accessions maintained as seeds and living plants, and recently started a cryopreservation programme.
