93份贵州地方辣椒资源品质性状分析

对93份贵州地方辣椒资源的品质性状进行了分析,结果表明:粗纤维含量在22.99%~44.06%之间,牛角椒含量最高,为33.71%;粗脂肪含量在11.49%~27.46%之间,锥形椒含量最高,为21.55%;蛋白质含量在12.81%~22.97%之间,指形椒含量最高,为18.78%;辣椒素含量在0.28~7.61 mg/g之间,指形椒含量最高,为4.47 mg/g;4个指标的平均隶属度值在0.21~0.68之间,超过0.60的辣椒资源有S106、S103、S072和S016;聚类分析表明,93份辣椒资源按平均隶属度大小可分为四大类型,即高品质型、中品质型、一般品质型和特殊品质型。贵州地方辣椒种质资源品质性状分析可为辣椒种质资源的创新利用、新品种的选育奠定基础。

Analysis on Quality Characters of 93 Guizhou Local Pepper Germplasm Resources

93 Guizhou local resources pepper quality traits were analyzed.The results showed that:crude fiber content was between 22.99％-44.06％,the highest was the cow horn shape pepper,the content was 33.71％;crude fat content was between 11.49％-27.46％,the cone shape pepper had the highest content of 21.55％,protein content was between 12.81％-22.97％,the finger shape pepper had the highest content of 18.78％,capsaicin content was between O.28-7.61 mg/g,the finger shape pepper had the highest content of 4.47 mg/g.The average membership values of the four indices was between 0.21-0.68,and four pepper resources contained S106,S103,S072 and S016 were more than 0.60.Cluster analysis showed that 93 pepper resources can be divided into four types,namely,high-quality,medium quality type,general type and quality of special quality type according to the average membership values.This research established foundation to the innovative use of pepper germplasm and breeding new varieties.
