In our province, the natural conditions are complex. The characteristics of “three-dimensional agriculture” are prominent. Under the long-term natural selection and manual selection, the local variety resources of extremely rich variety have been created. In order to collect, collate and make full use of these precious heritage, Under the guidance of the Central Government, in 1956, surveying and collecting local landraces of unprecedented scale were carried out by mobilizing local agricultural stations to serve as the basic force. Over 1,000 maize cultivars were collected and staged in Kunming in phases As of the end of five or eight years, more than 600 preliminary studies have been conducted on the distribution of maize varieties in our province and the main factors influencing the distribution of maize varieties. Selected 74 excellent performance of local varieties for production and utilization. In 1959, some local cultivars were studied and utilized again, from which 13 major economic traits were selected to perform better than that of the Golden Empress
