Flowering Rate

We determine the degree of flowering in the plant that is being characterized and that reached its maximum growth, 1 digit is coded

First we observe the absence or presence of flowering; when there is no flowering, we observe carefully if this is due to the absence of inflorescences even if these are rudimentary and consequently absence of flower buds, in this case they will have value 0, if there are inflorescences even if they are quite small or rudimentary or if they present abortion or abscission of small flower buds at the level of the pedicel joint, in this case they will have value 1; or if on the contrary there is presence of flowering, we will observe the intensity or degree of flowering; in this part we must consider that the different cultivars have different flowering periods, both in the beginning and in the duration of flowering (cultivars that flower in 1, 2 or 3 stages, corresponding to flowering of main inflorescence, inflorescence of secondary stems and flowering of branches); thus, it will take a value of 3 equivalent to scarce flowering, when there is usually the presence of about 2 to 4 flowers (buds, flowers, fruits and/or flower abscission) per inflorescence; it will take a value of 5 equivalent to moderate flowering, when there are usually 8 to 12 flowers (buds, flowers, fruits and/or flower abscission) per inflorescence; and finally it will take value 7 which is equivalent to profuse flowering, when there are usually around 18 to 20 or more flowers (buds or buds, flowers, fruits and/or abscission of flowers) per inflorescence, particularly smaller numbers of flowers per inflorescence can also occur as in the two previous levels (3 and 5) but there are many inflorescences per plant, this condition or aspect shows a profuse flowering; exceptionally, 90 to 120 flowers and buds per inflorescence are known in very few entries of the potato collection, these are also considered at this level. If we are comparing the same cultivars with different origins, all entries should flower at about the same time and with the same intensity. If they do not flower, the requirements for flower induction should be the same for all of them

Legend:

0

No buds In this case it will have a value of 0

1

Bud abortion Abscission of small flower buds at the level of the pedicel joint, in this case they will have value 1

3

Low flowering When there is usually the presence of about 2 to 4 flowers (buds, flowers, fruits and/or flower abscission) per inflorescence

5

Moderate flowering When usually 8 to 12 flowers (buds, flowers, fruits and/or flower abscission) are present per inflorescence

7

Profuse flowering When there are usually about 18 to 20 or more flowers (buds, flowers, fruits and/or flower abscission) per inflorescence, particularly smaller numbers of flowers per inflorescence can also occur as in the two previous levels (3 and 5) but very many inflorescences are present per plant, this condition or aspect shows profuse flowering; exceptionally 90 to 120 flowers and buds per inflorescence are known in very few entries of the potato collection, these are also considered at this level
