Genetic Molecular Linkage Map Construction and Genome Analysis of Rice Doubled Haploid Population

Abstract: A high density genetic linkage map comprised of aA. 4 loci was constructed from a doubled haploid population derived from a inter-subspecific cross between an Oryza satire L. ssp. Indica vari.t.v ("Zhaiyeqing 8") and a japonica variety ("Jingxi 17"). The genetic map consisted of 276 RFLP markers, 34 RAPD markers, 89 microsatellite markers, 10 AFLP markers, 26 markers based on telomeric repetitive associated sequence (TAS) and 9 isozyme markers. This genetic map was highly comparable with other high density rice genetic maps and had its unique feature which meritted it suitable for sustained genetic analysis.

Key words: Oryza sativa, Molecular markers, Genetic map, Recombination frequency, Skewed segregation
