I. Application and Amplification of General Seed Certification Standards

The General Seed Certification Standards are basic and, togetherwith the following specific standards constitute the standards for certi-fication of hybrid castor seed.

II. Land Requirements

Land to be used for seed production of hybrid castor shall be free ofvolunteer plants.

III. Field Inspection

A minimum of four inspections shaH be made as follows:

(1) the first inspection shall be made before flowering in order todetermine isolation, volunteer plants, outcrosses, planting ratio,errors in planting, internodal length, stem colour, type of leavesand other relevant factors;

(2) the second and third inspections shall be made during floweringto check isolation, offtypes, nature of bloom, petiole, leaves,raceme, sex expressivity, number of nodes to flower and otherrelevant factors;

(3) the fourth inspection shall be made prior to harvesting after theseed has attained maturity so that true nature of plant can be

. verified.

SUNFLOWER (Helianthus annus L.) HYBRIDS

I. Applicationand Amplificationof General Seed Certification Standards\

A. The General Seed Certification Standards are basic and, togetherwith the following specific standards constitute the standards for certi-fication of hybrid sunflower seed.

B. The General Standards are amplified as follows to apply speci-fically to the hybrids of sunflower:

1. Eligibility requirements for certification

(a) An inbred line to be aligible for certification shall be from asource such that its identity may be assured and approved bythe Certification Agency.

(b) Hybrid seed to be eligible for certification shall be the progenyof 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 resultingfrom self-pollination with selection.

(b) The foundation seed class shall consist of an approved malesterile line to be used as a female parent and an approved inbredline to be used as a male parent for the purpose of producinghybrid seed.

(c) A male sterile line shall be a strain ,A) carrying cytoplasmic-genetic male sterility, which sheds no viable pollen and is main-tained by the normal sister strain (B) which is used as pollinator.

(d) The certified class seed shall be the hybrid seed to be planted forany use except seed production.

II. Land Requirements

A seed crop of hybrid sunflower shall not be eligible for certificationif planted on land on which the same kind of crop was grown in the pre-vious year unless the cropes) grown in the previous year was of the samevariety and of an equivalent or higher class of certified seed and was/werecertified.

122
