[The application of RAPD technology in genetic diversity detection of Jute].

The fingerprints of 10 species including 27 accessions in genus Corchorus were investigated with the technique of RAPD. Twenty-five primers were screened from 119 random primers, and a total of 329 DNA fragments were amplified ranging from 0.3-3.

Approximate estimation of minimal sample size required for marker-assisted backcross breeding.

Backcross breeding is a useful method to transfer favorable alleles from a donor parent into a recipient parent. Marker-assisted selection (MAS) can speed up the process. To make an appropriate plan before using MAS in a breeding program, breeders need to know the minimal sample size of the progeny generation required.
