 Foreword 
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchanged 
within the Community will be removed.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.   
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. Draft East African Standards 
are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments 
received are discussed and incorporated before finalization of standards, in accordance with the procedures 
of the Community. 
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing .

standards specified in Table 1 or Table 2 are met. 
8.4 For field producing hybrid seed, the first inspections shall be conducted during the bud to early flower 
stage and two others during flowering. At least 50 % of the male parent plants shall be in flower and producing 
pollen at the time of female parent is in full flower. The heads of female plants shedding pollen shall be 
removed and disposed of in a manner that will prevent the dissemination of the pollen. Off-type male plants 
shall be removed from the field before pollination.  DRAFT UGANDA STANDARD ON PUBLIC REVIEW 
8 © EAC 201 4 – All rights reserved  
 8.5 If cytoplasmic male sterility is used to produce basic seed of parental lines, the first inspection shall be 
conducted before flowering, the second at early flowering and the third before the end of flowering. 
8.6 In the case of crops producing hybrid seed, the inspector shall check the identity of the parental 
materials following the official descriptors.   
8.7 For fields producing seed of OPV varieties, the first inspection shall be done prior to the flowering stage 
and the second inspection when the crop is 50% in flowering and the third inspection at physiological maturity. 
8.8 At the time of the first inspection, the inspector shall confirm with the grower the previous cropping of 
the field, checking on isolation and the proof of origin/authentication of the variety planted by using the labels,  
8.9 Depending on the degree of contamination, the inspector may give instructions for off-types, and 
diseased plants to be rouged so as to maintain the genetic purity.  
In case of noxious weeds found in the field, the grower shall be instructed to remove the weeds before 
harvesting. 
8.10 The field inspection report shall indicate the field status and comments for any corrective actions 
required such as re-inspection to confirm the field standards. All field inspection reports shall be provided to 
the grower and the seed enterprise after each inspection in a timely manner. The inspection report in Annex 
B, shall be signed by both the inspector and the grower or the grower’s representative.
