New Method of Heterotic Grouping of Maize Inbred Lines Using DNA Fingerprint--Genetic Background Analysis

doi:10.3321/j.issn:1000-7091.2003.04.017

Abstract

Abstract: Analysis 52 maize inbred lines and 15 contrast inbred lines using DNA fingerprint. Not using traditional cluster analysis method, just according to the genetic distance calculated between each inbred line and contrast inbred lines to classify the heterotic groups. The results show that using the method of genetic background analysis to classify the heterotic groups is very effective compare with the traditional cluster analysis. 52 maize inbred lines were classified into five heterotic groups conforming to using pedigree method except Huang C which was classified into Reid heterotic group.

Key words: Maize, DNA fingerprint, Heterotic grouping, New method
