Abstract: Genetic analysis of five fruit traits had been done based on a doubled haploid population of Capsicum annuum L.，obtained through anther culture from a cross between line '97403' and line '97410' and consisted of 103 lines. It was shown that the five fruit traits， i.e. transverse diameter of fruit，thickness of flesh，index of fruit shape，mass per fruit，vertical diameter of fruit，had the heritability of 82.3%，80.8%，80.5%，75.7%，70.9% respectively，while the least number of genes controlling those characteristics was 20.6，8.4，6.1，33.9，10.0 respectively. Based upon estimated coefficients of skewness (g1) and kurtosis (g2) of those traits，complementary gene interaction，it was shown that between the two traits such as mass per fruit and transverse diameter of fruit，and it was possible that the genes controlling the trait of thickness of flesh had the complementary interaction too. However，the gene interaction was found absent in the two traits of vertical diameter of fruit and index of fruit shape.
