Drought stressed areas devoted to maize production occupy 38 to 42 percent of the total maize growing area but contribute only about 17 percent to the total maize production. Unreliable rains that are very poorly distributed during crop growth and non availability of suitable maize varieties are responsible for such significant yield reduction. To minimize the yield reduction and thereby reduce farmers risk of crop failure, germplasm development work has been started by Awasa College of Agriculture in 1976 and Nazareth Maize Program in 1992. Since then several early maize varieties were developed by the College of which ACV-3 and ACV-6, drought tolerant materials, were identified from the screening and multi-site evaluation by Nazareth Maize Program. These promising materials have been directed to different breeding schemes for further evaluation. Although the major emphasis at present is placed on breeding for earlines, the future breeding strategy will focus on the development of drought tolerant maize varieties. Along with this, mechanism of drought tolerance will be studied.
