Abstract:
In order to screen out fiber industrial hemp varieties suitable for cultivation in Jilin Province, the field identification of 9 fiber hemp industrial varieties were carried out. The growth traits and yield of industrial hemp were comparative analysis. The results showed that the earliest emergence date of Huoma No.1 was May 12 under the same sowing date. The ratio of male to female was higher in all varieties. The day of technical mature were 100-109 d. The highest hemp was Qingma No.1 which average plant height was 340.29 cm. The best primary stem yield was 9 822.73 kg·ha
-1, and the dry stem yield was 8 982.13 kg·ha
-1. The primary stem yield of Qingma No.1, Longdama No.3, Huoma No.1, Fenma No.3, H20 and Fenma No.4 were very significant increased than Gongzhuling Hemp. The general hemp rate of Qingma No.1 was highest of 20.14%. The total hemp rate of Qingma No.1, Fenma No.4, Longdama No.3 and Huoma No.1 was higher than Gongzhuling Hemp. The fiber yield of Qingma No.1, Huoma No.1, Fenma No.4 and Longdama No.3 was all significant higher than Gongzhuling Hemp.Therefore the varieties of hemp for fiber industry were recommended to be planted in Jilin Province: Qingma No.1, Huoma No.1, Fenma No.4 and Longdama No.3.
