Abstract: 【Objective】 In order to provide germplasm resources and theoretical basis for drought-resistant breeding, 283 maize material were selected for comprehensive evaluation of drought-resistance coefficient and yield in well-watered under water-stressed. 【Methods】 Using the method of double selection of drought resistance coefficient and yield in well-watered, the changes of drought resistance, yield and phenotypic characteristics of maize in well-watered were analyzed and studied. 【Results】 The results showed that under well-watered and water-stressed, the yield was normally distributed, the drought resistance coefficient showed skewed distribution, the average drought resistance coefficient was 0.617, and the stress intensity was 0.383. 15 excellent inbred lines and 3 crosses were selected for both high yield and drought resistance. The days of silking (58.5-71.0 days), plant height (150-208.1 cm), ear height (44.6-77.5 cm), number of grains per ear (295-502 grains per ear), and 100 grain weight (16.5-36.0 g) of inbred lines with excellent drought resistance in well-watered and yield per plant (60.4-90.5 g) showed certain range characteristics. The hybrids with excellent drought resistance had days of silking (61.5-63.0 days), plant height (275.6-287.8 cm), ear height (103.8-115.0 cm), number of grains per ear (538-692 grains per ear), and 100 grain weight (34.9-38.9 g) in well-watered and yield per plant (165.7-186.8 g) showed a certain range. The yield per plant and drought resistance of excellent drought resistant materials were higher than the average level, while the growth period, plant height, spike height, grain number per spike and hundred grain weight were lower than the average level. Grain number per spike and hundred grain weight had a complementary relationship. 【Conclusion】 A total of 18 excellent maize materials with high yield and drought resistance are selected. The yield per plant of 15 inbred lines in well-watered is not less than 60 g, and the drought resistance coefficient was not less than 0.8. The yield per plant of the 3 hybrid combinations in well-watered is not less than 160 g, and the drought tolerance index of the varieties is greater than 1.5. The 18 materials have high yield under normal irrigation conditions and strong drought resistance in terms of grain number per spike, which can be used in breeding.
