Discussion on Harmonized TG• P.1, 1.These TG apply to all varieties of <strong>Carica</strong> <strong>papaya</strong> L. ofthe family <strong>Carica</strong>ceae.• P.1, 2.3.The minimum quantity of plant material should be:200 seeds in the case of seed-propagated varieties,or6 hermaphrodite plants in the case of vegetativelypropagated varieties.• P.3, 4.2.2.Each test should be designed to result in a total of atleast 25 hermaphrodite plants or at least 6hermaphrodite plants or plant parts.3 rd WORKSHOP FOR COOPERATION IN HARMONISATION OF TGs AND DUS TESTKuala Lumpur, August, 2 nd –6 th 2010
• P.3, 4.2.3.For the assessment of uniformity apopulation standard of 1% and anacceptance probability of 95% should beapplied. In the case of a sample size of 6hermaphrodite plants, one off-type isallowed.3 rd WORKSHOP FOR COOPERATION IN HARMONISATION OF TGs AND DUS TESTKuala Lumpur, August, 2 nd –6 th 2010
