Genetic Diversity

Estimation of Genetic Diversity

1. Divergent parents carrying different favorable genes are used in crossing programme for realizing trsangressive segregants in self-pollinated crops and for creating heterotic hybrids in cross pollinated crops.
2. DNA selected for diversity analysis should preferable belongs to non-overlapping expressed part of the genome. The RFLP markers, if included in the analysis should be generated with cDNA probes.
3. For genotyping large number of collections available in the gene bank, a PCR based marker system will serve better by way of saving time and efforts.
