Screening Experiment of New Flax Varieties in Tianshui Dry Farming Area
In order to select the flax varieties suitable for Tianshui dry farming area with characters of high yield,high quality and good resistance,17 flax varieties were selected for the introduction experiment with Longya 13,the main local flax variety,as the control.The results showed that no differences were found among varieties in terms of the growth period and the growth stages.No powdery mildew was detected in the fields of Longya 14,Jinya 12,0559,0523-2-13,09162 and 0354,whereas no lodging was found at the late growth stage of Neiya 9,Longya 10,Longyaza 1,0818-6-13,0559 and 0354.The yield of Jinya 12 was the highest,reaching 2 035.00 kg/ha,which was 63.36%higher than that of the control variety Longya 13.The yield of Tianya 9 was 1 653.50 kg/ha,which was 32.73%higher than that of the control.The yield of Longya 11,Longya 10,0559,Longyaza 2 and Longya 14 were 1 466.50,1 450.33,1 433.83,1 402.92 and 1 352.08 kg/ha,respectively,which were 17.72%,16.42%,15.10%,12.62%and 8.54%higher than that of Longya 13,respectively.Overall,it is believed that Jinya 12,Longya 14,Longyaza 1,and Tianya 9 have excellent agronomic traits,high yield,good quality,and strong stress resistance,and can be used as the main varieties for cultivation in the Tianshui dryland area.0559 is avariety with high yield,full grains and high thousand-grain weight which is also recommended to promote.The plant heights of 09162,0523-2-13,0354,and Longya 14 are all higher than 75 cm and have good processing length,which can be prioritized for use in areas where both oil and fiber varieties are needed.
