Variability of quantitative traits and SSR polymorphism of soybean genotypes: [Master thesis]
2006
Djordjevic, V.
Variability of quantitative traits in 14 soybean genotypes was investigated. Variability of morphological traits, phenological traits and seed chemical content was measured. Also, molecular markers (SSR- simple sequence repeats) were used to determine genetic distances among soybean genotypes. Results indicated great variability of quantitative traits. The phenotype distance matrix was calculated as well. Phenotype distances between pairs of genotypes ranged from 0.124 to 0.785. Cluster analysis showed great influence of vegetation duration on all other traits. Genetic distances between pair of genotypes obtained by molecular markers varied from 0.096 to 0.759. Cluster analysis divided all genotypes into 4 groups. By the geographical principle, the genotypes were divided into two populations - the North American one and the Novi Sad one. Greater gene diversity was recorded in the North American population, in which 9 alleles on 6 loci showed significant differences in allele frequencies. Found in this set of genotypes were sister lines, so SSR analysis was used to construct an idiogram of three linkage groups.
