Abstract:

The suitable varieties of Helianthus tuberosus for planting in Yan'an were screened out to solve the problem of single variety and promote the industrialization of H. tuberosus. We conducted a field comparison test on 6 introduced H. tuberosus varieties and 1 local variety, and investigated the growth period, agronomic traits and economic traits of each variety in field. The results show that the comprehensive traits of ‘Langyu No.1’ and ‘Langyu No.2’ are relatively good, with the yield of 57378.68 and 56228.10 kg/hm2, respectively, which is 5.11% and 3.00% higher than that of the control. The rest of the varieties show average performance, their yields are lower than that of the control and should be further tested under field condition. ‘Langyu No.1’ and ‘Langyu No.2’ are more suitable for planting and promoting in Yan’an.
