优质高产、抗病性强的辣椒品种比较试验

Comparative Experiment on Pepper Varieties of High-quality,High-yield and Strong Disease Resistance

为选择适宜贵州省关岭地区优质高产、多抗性的辣椒新品种,保证区域辣椒产量的稳定,以当地干椒品种遵辣6号和鲜椒品种长辣7号为对照,对比分析新引进的2个干椒品种和4个鲜椒品种的栽培表现。结果表明:干椒引进品种中,遵辣2165和湘研702均表现出生长特性好、抗病能力强、产量高的特点,其株高和单株结果数均显著高于对照,以湘研702抗病能力最强,病毒病、疫病和青枯病发病率最低,湘研702和遵辣2165的产量较对照遵辣6号每667 m^(2)分别增加101.90 kg和70.82 kg,鲜椒产量分别增加266.61 kg和205.56 kg,2个品种的干、鲜椒产量均显著高于对照品种;对于鲜椒品种而言,卓香27号的生长特性好,且抗病能力最强,其病毒病、疫病和青枯病发病率最低,667 m^(2)产量高于对照长辣7号,为1641.02 kg,其他鲜椒品种产量均显著低于对照。综上,干椒品种遵辣2165、湘研702和鲜椒品种卓香27号适宜在贵州关岭地区进行推广应用。

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 2 pepper of'Xiangyan 702'and'Zunla 2165'increased by 101.90 kg per 667 m^(2) and 70.82 kg per 667 m^(2),respectively,2 and the yield of fresh pepper increased by 266.61 kg per 667 m^(2) and 205.56 kg per 667 m^(2),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 1641.02 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.
