The breeding program of the cultivar Giza 86 was conducted at El-Gemmeiza Experimental Station at El-Gharbia Governorate Egypt, during 2017-2020 seasons to initiate a nucleolus. In 2017 season sixty type plants were selected from the breeding nursery of Giza 86 cotton cultivar that produced sixty progenies (increase A) in 2018. From the latter, 23 families were selected to form (increase B) in 2019, According to the statistical analysis of yield trial which included the twenty three families and comparisons of the latest two strains in cultivation of Giza 86, ten elite families were selected and their seed were massed carefully together to form the nucleolus (Breeder's seed) in 2020 season. The results obtained here indicated that, the pure line method in the sense of pedigree selection for annually renewing Giza 86 breeder's seed could prevent genetic contamination. Meanwhile, the selection technique for producing breeder’s seed of Giza 86 cultivar was valid and proved to be effective in holding the true type of the variety
