From 2015 to 2016, Chongqing Project Group of the Third National Survey and Collection Action on Crop Germplasm Resources carried out field survey and collection on crop germplasm resources in 12 key counties and districts. A total of 1379 resources were collected, among which 122 maize landraces were found. The distribution analysis for these landraces indicated that more resources were found in Northeast and South of Chongqing and Wuling Mountain Area, fewer accessions were collected from the West of Chongqing. The vertical distribution showed that more accessions were collected in hilly area of 800-1000 meters altitude and mountain area of 1400-1600 meters. The analysis of morphological traits found that most of the collected maize resources were hard grain and white color. Some elite germplasm resources were also found through the action. For example, the maize landrace Dazihuang is highly resistant to ear and kernel rot; Yejizhua has a strong root system, which is highly resistant to barren; Tiezibai, Qingkezao and Jinhuangzao has a good quality for eating and starch processing. Conclusively, the special maize landraces have a strong prospect for modern varieties utilization in quality, stress resistance, adaptability and nutrient efficient utilization.
