Abstract
Genetic variability is the basic for developing new improved varieties. Genetic variability can be increased through mutation techniques. The aim of this study was to analyze the genetic diversity of the M1 cayenne pepper population resulting from gamma-ray irradiation based on generative characters. The genetic analysis carried out involved estimating genetic variability and broad-sense heritability. The research was conducted in the experimental field of of the Agrotechnology Study Program, UPN Veteran Yogyakarta, using 148 mutant genotypes (M1) and three comparison varieties. The experimental design used was an Augmented Design. The results show that the characteristics number of fruit per plant, fruit weight per plant, weight per fruit, stalk length, fruit diameter, thick fruit had broad genetic variability and a high broad-sense heritability.
