Abstract

Anther culture was utilized to develop haploid plants in wheat .This study was carried out at Plant Biotechnology Department, Genetic Engineering and Biotechnology Research Institute ( G E B R I ) from  2009  to  2014  years .  Three varieties of wheat were used , Sids1, Gemmeiza 9  and Giza 168. The studied factors were, cold and chemical pretreatments, growth regulators concentrations of 2,4-D and kinetin and effect of  source of spikes . The results indicated that the cold pretreatment had no effect on anther response of three wheat varieties, the chemical pretreatments by sterilization  substances (ethanol alcohol 70 % or mercurec chloride 1g /L or thiourea 2 g /L ) were very important and essential to induce callus from anther . The three treatments of ( 1mg /L 2,4-D ) , ( 2 mg /L 2,4-D ) and ( 2 mg /L  2,4-D + 0.1 mg /L kinetin ) gave the highest response of callus induction and plant regeneration . Androgenesis improved with increasing the cultured area which the spikes were collected from it .
