[Parent grouping of 31 elite inbred lines in hot pepper (Capsicum annuum L.)].

Genetic differences were examined among thirty-one elite inbred lines in Capsicum annuum L. Two types of analytic technologies, i.e. SRAP markers and genotypes of traits, were used, and their relative effectiveness was compared. 27 of 30 primer combinations could amplify 310 polymorphic bands among inbred lines, indicating SRAP marker was efficient to detect polymorphism among pepper inbred lines. A dendrogram of 31 inbred lines based on SRAP markers and Yule coefficients could basically separate lines of C. annuum var. grossum and C. annuum var. longum, and reveal the pedigrees of inbred lines. A dendrogram of 31 inbred lines based on genotypes of traits and standardized Euclidean coefficients could separate lines of C. annuum var. grossum and C. annuum var. longum. The SRAP marker genetic distances were correlated with distances based on the genotypes of traits. These results and their application in the development of hot pepper F1 hy-brids were also discussed.
