Genetic analysis on the dominant non-susceptibility to densonucleosis virus type 1 in the silkworm, Bombyx mori

Genetic analysis of Nid-1 (non-infection with densonucleosis virus type 1), showing complete resistance against DNV-1, was darned out. From the linkage analysis, Nid-1 was linked to Bm and btssup(2), on the seventeenth linkage group. Two point analysis between Bm and Nid-1 showed that the distance b...

Summary:Genetic analysis of Nid-1 (non-infection with densonucleosis virus type 1), showing complete resistance against DNV-1, was darned out. From the linkage analysis, Nid-1 was linked to Bm and btssup(2), on the seventeenth linkage group. Two point analysis between Bm and Nid-1 showed that the distance between them was 20.8% when calculated from the 53 recombinants from 285 backcross segregants. Next, three point analysis was carried out between the genes, bts, ow and Nid-1, which were located at the midst of the chromosome, and the order and the loci of them were bts (30.1), Nid-1 (31.1) and ow (36.4) from the recombination values of the backcrosses.
