Abstract:

The aim is to promote the industrial development of high-oleic peanut in Sichuan by selecting high-oleic peanut varieties which could adapt to the local ecological environment rapidly and exploring high-oleic peanut germplasm resources of high quality. 16 varieties of local or introduced high-oleic peanut were tested. The economic characters, yield, growth characteristic, resistance and single-plant yield were compared by sample survey and data analysis method. ‘Zhonghua 415’, ‘Jihua 13’, ‘Yuhua 37’, ‘Kainong 1760’ and ‘Jihua 16’ had an outstanding performance in pod size, full pod rate, kernel percentage, 100-pod mass, yield and taste; ‘Zhonghua 415’, ‘Yuhua 37’, ‘Huayu 961’, ‘Jihua 13’ and ‘Jihua 16’ had a well performance in branching number, seedling emergence rate, growth vigour and resistance; ‘Kainong 1760’, ‘Jihua 13’, ‘Jihua 16’, ‘Yuhua 37’ and ‘Zhonghua 415’ had an excellent performance in total pod number per plant, full pod number, full pod rate and yield per plant. The introduced varieties such as ‘Jihua 13’, Jihua 16’, ‘Yuhua 37’and ‘Zhonghua 415’ with good characters should be promoted for further demonstration, and it still takes some time for the varieties introduced from other provinces to adapt to local ecological environment in Sichuan.
