1. Application and Amplification of General Seed Certification Standards

A. The General Seed Certification Standards are basic and, togetherwith the following specific standards constitute the standards for certifica-tion of hybrid barley seed.

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

1. Eligibility requirements for certification

(0) 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 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 class seed shall consist of an approved malesterile line to be used as a female parent and 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 seed class shall be the hybrid seed to be planted for-any .use except seed production.- . .---.--


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


A minimum of four inspections shall be made as follows:

(1) the first inspection shall be made before flowering in order todetermine isolation, presence of volunteer plants, outcrosses,

':",,-platUirlgr~tio,; 5rrors in pla~ting and other relevant factors;(2f" the seconcCand third inspections shall be made during flowering

to check isolation, offtypes, pollen shedders in female parent and~ther relevant factors;

(3) the fourth inspection shall be made at maturity and prior toharvesting to verify true nature of the plant and other relevantfactors.
