摘　　要：对朝天椒18个性状(10个表型性状和8个数量性状)进行多样性分析,并介绍了贵州省辣椒研究所目前收集保育的156个朝天椒种质材料的地理分布情况。结果表明:在朝天椒的质量性状中果形的遗传多样性指数最高为1.509 7,数量性状中株高遗传多样性指数最高为2.169 9,对产量影响较大的单株结果数和单果重的遗传多样性指数分别为1.779 3和1.842 6。现有朝天椒种质材料主要来源于黔北地区,占总材料数的63.46%。The results from analyzing 18 traits including 10 phenotypic and 8 quantity traits and investigating the geographical distribution condition of 156 hot pepper varieties collected by Guizhou Sericultural Institute show that the highest genetic diversity index of fruit shape and plant height is 1. 509 7 and 2. 169 9 in quality traits and quantity traits respectively, the genetic diversity index of fruit number per plant and single fruit weight is 1. 779 3 and 1. 842 6 separately and 63.46% of total hot pepper germplasm resources is from northern areas of Guizhou mainly.
