Voorbeeldzinnen

1. The ratio of male-sterile parent seed to male-fertile parent shall not exceed two to one.
2. male parent, plants which have shed pollen while 2 % or more of the female plants have receptive flowers,
3. Where the condition laid down in Annex I(3)(B)(b)(dd) cannot be satisfied, the following condition shall be met: where for the production of certified seed of hybrids of Helianthus annuus a female male-sterile component and a male component which does not restore male fertility have been used, the seed produced by the male-sterile parent shall be blended with seed produced by the fully fertile seed parent. The ratio of male-sterile parent seed to male-fertile parent shall not exceed two to one.
4. Where the condition laid down in Annex I(3)(B)(b)(dd) cannot be satisfied, the following condition shall be met: where for the production of certified seed of hybrids of Helianthus annuus a female male-sterile component and a male component which does not restore male fertility have been used, the seed produced by the male-sterile parent shall be blended with seed produced by the fully fertile seed parent.
5. During experiments, marmosets and tamarins can generally be kept with a compatible same-sex animal (twins, parent/offspring) or in male-female pairs, using contraception.
6. The level of male sterility of the seed-bearing parent line shall be assessed by examining the flowers for the presence of sterile anthers and shall not be less than 99,7 %.
7. The level of male sterility of the seed-bearing parent line shall be assessed by examining the flowers for the presence of sterile anthers and shall not be less than 99,9 %
8. in crops to produce certified seed of hybrid varieties of Gossypium hirsutum and/or Gossypium barbadense, the minimum varietal purity of both the seed-bearing parent and the pollen parent line shall be 99,5 % when 5 % or more of seed-bearing plants have pollen receptive flowers. The level of male sterility of the seed-bearing parent line shall be assessed by examining the flowers for the presence of sterile anthers and shall not be less than 99,7 %.
9. in crops to produce basic seed of parental lines of Gossypium hirsutum and Gossypium barbadense, the minimum varietal purity of both the female and male parental lines shall be 99,8 % when 5 % or more of seed-bearing plants have pollen receptive flowers. The level of male sterility of the seed-bearing parent line shall be assessed by examining the flowers for the presence of sterile anthers and shall not be less than 99,9 %
