Abstract: 【Objective】 To indentify the drought resistance of 28 maize inbred lines with a view to providing a basis for maize germplasm innovation and varieties breeding of drought resistant in Guangxi. 【Method】 Under normal irrigation and drought stress, ear length, ear diameter, ear rows number, row kernels number and 100-kernels weight were measured, and yield index was also determined.Drought resistances of different maize inbred lines were evaluated by the D value of ear characters drought coefficient and the drought index of yield. 【Result】 The D value obtained by subordinate function method ranged from 0.318,6 to 0.985,7, including 12 inbred lines with strong drought resistance, 10 with moderate drought resistance and 6 with weak drought resistance.Yield drought index ranged from 0.387,7 to 1.458,3, including 7 inbred lines with strong drought resistance, 10 with moderate drought resistance and 11 with weak drought resistance.The relationship between the two kinds of evaluation results was significantly correlated with a coefficient of 0.740,2. 【Conclusion】 Both yield drought resistance index and subordinate function method can be used to evaluate drought resistance of maize inbred lines.Two aspects of the evaluation results show that D1101, Q901, VN, Gui39722, YD2, D1113 and SP221 were strong drought resistance inbred lines.
