Experiments to determine radiation dose effective for increasing wheat genetic diversity has been conducted from March to May 2015. Wheat seeds radiation was carried out at Research Center and PATIR BATAN, South Jakarta, followed by wheat growth screening at greenhouse of PATPKP UNAND at Alahan Panjang, Municipality of Solok, the Province of West Sumatra. Wheat genotypes of IS-Jarissa dan GURI 6 UNAND were subjected to gamma radiation as follow: 0.1; 0.2; 0.3; 0.4; 0.5; 0.6; 0.7; 0.8; 0.9; 1.0 kGy; and 0 kGy as control treatment. The wheat seeds were then grown in a mixture of soil and cow manure (3:1) w/w in a greenhouse. Data demonstrated that increasing the radiation doses resulted in decreasing in wheat growth. The effective doses of gamma radiation were 0.2 and 0.3 kGy. No wheat grown observed from the treatment groups of 0.5kGy gamma radiation and higher.
