Zinnia elegans Jacq.has a large potential as a cut flower because it is very suitable to be cultivated in Indonesia. X-ray irradiation have been done to increased the diversity of flower Zinnia elegans Jacq. Then get selected. This study was conducted to determine the flowers diversity, shapes and colors proportions in M6 populations. This research was conducted in Krapyak, Triharjo, Sleman, Yogyakarta from March 2012 until August 2012. The flowers with character pompom and red purple color were taken from 140 plants of M4 population. This selection produced 14 plants with purple red and white color of M5 population.
