1. Key words: rye, Secale cereale, RFLP, genetic map, chromosome 7R, colinearity.

2. Only a small number of genetic markers and one genetic map have been published for Broomcorn millet10–15

3. Every site of a gene (locus) on a genetic map, established on the basis of the frequency of crossing-over of portions of a chromosome, is linked on a Cytological map to …

4. Comparative mapping of Chalkiness components in rice using five populations across two environments Our results identified 79 QTL associated with six Chalkiness traits using five populations across two environments and yielded an integrated genetic map, indicating most of the QTL clustered together and could be detected in different backgrounds.
