  1. 7.3.11 - Auricle: colour (7.3.11) Stage: late vegetative
  2. 7.3.22 - Flag leaf: attitude (early observation) (7.3.22) Observed near the collar. Angle of attachment between the flag leaf blade and the main panicle axis. Record the average of five samples. Stage: cultivated species at anthesis; wild species seven days after anthesis
  3. 7.3.25 - Culm: lenght (7.3.25) Measured from ground level to the base of the panicle. Record the average of five actual measurements, to the nearest cm. Stage: cultivated species after flowering to maturity; wild species seven days after anthesis.
  4. 7.3.25a - Plant: height (7.3.25a) Measurement in cm from soil surface to the tip of the tallest panicle (awns excluded). Stage: after flowering to maturity.
  5. 7.3.28 - Culm: anthocyanin colouration on nodes (7.3.28) The presence and distribution of purple colour from anthocyanin, observed on the outer surface of the nodes on the culm. Stage: after flowering to near maturity
  6. 7.3.29 - Culm: underlying node colour (7.3.29) The underlying colour of the outer surface of the nodes on the culm, ignoring any anthocyanin colouration. Stage: after flowering to near maturity
  7. 7.3.34 - Flag leaf: attitude (late observation) (7.3.34) Observed near the collar. Angle of attachment between the flag leaf blade
    and the main panicle axis. Record the average of five samples. Stage: maturity
  8. 7.4.18 - Panicle: length [cm] (7.4.18) Length of main axis of panicle measured from the panicle base to the tip. Record the average of five representative plants. Stage: seven days after anthesis or upon full panicle exsertion.
  9. 7.4.19 - Panicle: attitude of main axis (7.4.19) Stage: near maturity.
  10. 7.4.2 - Stigma: colour (7.4.2) Observed at anthesis (between 0900 and 1400) using a hand lens.
  11. 7.4.20 - Panicle: attitude of branches (7.4.20) The compactness of the panicle, classified according to its mode of branching, angle of primary branches, and spikelet density. Stage: cultivated species near maturity; wild species seven days after anthesis.
  12. 7.4.22 - Panicle: exsertion (7.4.22) Extent to which the panicle is exserted above the flag leaf sheath. Stage: near maturity.
  13. 7.4.6 - Lemma: colour of apiculus (early observation) (7.4.6) Stage: cultivated species after anthesis to hard dough stage (pre-ripening stage); wild species at anthesis.
  14. 7.4.9 - Awns: distribution (7.4.9) The presence and distribution of awns along the panicle. Stage: flowering to maturity.
  15. 7.5.10 - Sterile lemma: length [mm] (7.5.10) Record the average length of five spikelets. For spikelets with symmetrical sterile lemmas (i.e. Sterile length the same on both sides), record the length here. For spikelets with asymmetrical sterilelemmas (i.e. Sterile lemma on one side longer than that on the other), record here only the length of the shorter sterile lemma (see 7.5.11 for the longer sterile lemma).
  16. 7.5.11 - Longer sterile lemma: length [mm] (7.5.11) (Only for spikelets with asymmetrical sterile lemmas). Record the average length of the longer sterile lemma on five spikelets.
  17. 7.5.13 - Sterile lemma: colour (7.5.13) Observe five representative plants.
  18. 7.5.20 - Caryopsis: length [mm] (7.5.20) Caryopsis: length [mm]
  19. 7.5.22 - Caryopsis: shape (7.5.22) Caryopsis: shape
  20. 7.5.23 - Caryopsis: pericarp colour (7.5.23) Caryopsis: pericarp colour
  21. 7.5.4 - Lemma and palea: pubescence (7.5.4) Visual assessment of the presence and distribution of mature grains using a hand lens.

  1. 7.2.3.1 - Number of days from effective seeding to main heading data [d] (7.2.3.1) Number of days from effective seeding date to main heading date
  2. 7.2.3.2 - Main heading date [YYYYMMDD] (7.2.3.2) Date on which 80% of the plants are heading [YYYYMMDD]
  3. 8.1.a - Phenotypic acceptability [IS-10] (8.1.a) Breeding objectives for each location vary. The score should reflect overall acceptability of the variety in the location where it is being grown. Stage: maturity.


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.
