Jute

The Plant Variety Protection (PVP) Authority decides when, where and in what quantity and quality of the seed and the plant material required for testing the variety is to be delivered. Applicants submitting material from a country other than India must make sure that all customs formalities are complied with. The minimum quantity of seed to be supplied by the applicant should be:

1000 grams      (in one submission only)
The seed should meet the minimum requirements for germination capacity, moisture content and physical purity prescribed for certified seed in India. Especially for storage, which requires a higher standard, the applicant should state, the actual germination capacity which should be as high as possible but not less than 85%. The seed supplied should be visibly healthy, not lacking in vigour or affected by any important pest or disease.
The seed material must not have undergone any treatment unless the competent authority allow or request such treatment. If it has been treated, full details of the treatment must be given

_______________________________________________________________________________________

III. Conduct of tests

The minimum duration of tests should normally be two independent growing seasons with reference to the ecosystem of the variety submitted for DUS test.
The tests should normally be conducted at two test locations. If any important characteristic of the variety cannot be seen at these places, the variety may be tested at an additional place.

The field test should be carried out under conditions ensuring normal growth. The size of the plots should be such that plants or parts of plants may be removed for measurement and counting without prejudice to the observations, which must be made up to the end of the growing period. Each test should include a minimum of 500 plants which should be divided among three replications. Separate plots for observation and for measurement can only be used if they have been subjected to similar environmental conditions.

Test plot design

Number of rows:	:	4
Row length	:	5 m
Row to row distance	:	40 cm
Plant to plant distance	:	5 to 7 cm
Number of replications	:	3

Observations should not be recorded on plants in border rows.
Additional tests for special purpose may be established.

IV. Methods and observations

The characteristics described in the Table of characteristics should be used for the testing of varieties and hybrids for DUS.
For the assessment of distinctness and stability all observations should be made on at least 30 plants or parts of 30 plants which should be divided among three replications (10 plants in each replication).
For the assessment of uniformity of characteristics on the plot as a whole (visual assessment by a single observation of a group of plants or parts of plants), the number of aberrant plants should not exceed 3 in 500.
For the assessment of colour characteristics, it is recommended that Royal Horticultural Society (RHS) colour chart should be used.
Unless otherwise indicated, all observations on the leaf should be recorded on sixth leaf from the top on main stem.

V. Grouping of varieties

The collection of varieties to be grown should be divided into groups to facilitate the assessment of distinctness. Characteristics which are suitable for grouping purposes are those which do not vary, or to vary only slightly, within a variety. Their various states of expression should be fairly evenly distributed through out the collection.
It is recommended that the competent authorities use the following characteristics for grouping varieties:

i.       Seedling: premature flowering resistance (C. olitorius varieties only) (characteristic 1)

ii.       Stem: colour (characteristic 4)

iii.       Time of flowering (characteristic 9)

VI. Characteristics and symbols

To assess distinctness, uniformity and stability, the characteristics and their states as given in the table of characteristics should be used.
Notes (1 to 9), for the purpose of electronic data processing are given opposite the states of each characteristic.
Legend:

(*)Characteristics should be used every growing period for the examinations of all varieties and should always be included in the descriptions of the variety, except when the state of expression of a preceding characteristic or regional conditions render this impossible

(+) See explanations on the Table of characteristics in Chapter VIII.
The optimum stage of plant growth for assessment of each characteristic is indicated in the sixth column of Table of characteristic
Type of assessment of characteristic indicated in column seven of Table of characteristic is as follows.

MG : Measurement by a single observation of a group of plants or parts of plants

MS : Measurement of a number of individual plants or parts of plants

VG : Visual assessment by a single observation of a group of plants or parts of plants

VS : Visual assessment by observation of individual plants or parts of plants
