Comparative Experiment on Pepper Varieties of High-quality,High-yield and Strong Disease Resistance
In order to select new varieties of pepper that were suitable for the Guanling region of Guizhou province with high quality,high yield and multiple resistance,and ensure the stability of regional pepper production,the local dry pepper variety'Zunla No.6'and the fresh pepper variety'Changla No.7'were used as controls to compare and analyze the cultivation performance of two newly introduced dry pepper varieties and four fresh pepper varieties.The results showed that both'Zunla 2165'and'Xiangyan 702'showed good growth characteristics,strong disease resistance and high yield,whose plant height and number of fruit per plant were significantly higher than those of the control.'Xiangyan 702'had the strongest disease resistance,and the lowest incidence rate of viral disease,blight and bacterial wilt.Compared with the control,the yield of dry pepper of'Xiangyan 702'and'Zunla 2165'increased by 101.90 kg per 667 m2 and 70.82 kg per 667 m2,respectively,and the yield of fresh pepper increased by 266.61 kg per 667 m2 and 205.56 kg per 667 m2,respectively,which significantly higher than those of control.For fresh pepper variety,'Zhuoxiang No.27'had good growth characteristics and the strongest disease resistance,whose incidence rate of virus disease,blight and bacterial wilt were the lowest and the yield was higher than the control,reaching 1 641.02 kg per 667 m2.The yields of other fresh pepper varieties were significantly lower than that of the control.In summary,the dry pepper varieties'Zunla 2165''Xiangyan 702'and fresh pepper varieties'Zhuoxiang No.27'were suitable for promotion and application in the Guanling area of Guizhou province.
