SUNFLOWER (Helianthus annus.L.)HYBRIDS

I. Application and Amplification of General Seed Certification Standards

A. The General Seed Certification Standards are basic and together with the following specific standards

constitute the standards for certification of sunflower hybrid seeds.

B. The General standards are amplified as follows to apply specifically to the hybrids of sunflower:

1. Eligibility requirements for certification

(a) An inbred line to be eligible for certification shall be from a source such that its identity may

be assured and approved by the Certification Agency.

(b) Hybrid seed to be eligible for certification shall be the progeny of two approved inbred lines, one of

which shall be male sterile.

2. Classes and sources of seed

(a) An inbred line shall be a relatively true breeding strain resulting from self -pollination with selection.

(b) The Foundation class seed shall consist of an approved male sterile line to be used as a female parent

and approved inbred line to be used as a male parent for the purpose of producing hybrid seed.

pollen and is maintained by the normal sister strain (B) which is used as pollinator;

(d) The Certified class seed shall be the hybrid seed to be planted for any use except seed production.

II. Land requirements

A seed crop of Ornamental sunflower hybrid shall not be eligible for certification if planted on land on which the same

kind of crop was grown in the previous year unless the crop (s) grown in the previous year was / were of the

same variety and of an equivalent or higher class of certified seed and was/ were certified.

III. Field Inspection

A minimum of three inspections shall be made as follows:

1. the first inspection shall be made at the stage of 6 - 7 pairs of leaves in order to determine isolation,

outcrosses, volunteer plants, planting ratio, errors in planting, designated disease and other relevant factors .

2. the second and third inspection, shall be made during flowering to check isolation, pollen shedding heads,

offtypes and other relevant factors;

3. the fourth inspection shall made at maturity prior to harvesting to verify designated diseases, true nature of

plant and head, characteristics of seed and other relevant factors.
