Abstract
The breeding program of Giza 87 was conducted at Sakha Agricultural Research Station, Kafr El-Sheikh district during 2010 - 2013 growing seasons. In 2010 season sixty type plants were selected from the breeding field of Giza 87 variety and furnished sixty progenies (increase A) in 2011. From the later, seventeen families were selected to descend increase B in 2012. According to the statistical analysis of yield trial which included the seventeen families and comparisons of the latest lines of Giza 87, six elite families were selected and the seeds were carefully massed together to form the nucleolus (breeder's seed) in 2013 season. The results obtained indicated that, the pure line method in the sense of pedigree selection for renewing annually Giza 87 breeder's seed could produce high genetically pure seeds and in the same time, prevent genetic contamination. Meanwhile, the selection technique for producing breeder's seed of Giza 87 variety was valid and proved to be effective in holding this variety according to the standard type of Giza 87.
