Single nucleotide polymorphisms - estimated heterozygousity on partial cassava inbred line development
Abstract
The effect of selfing and heterozygousity were analyzed in five S1 families. Results are discussed with a view to selecting the best performing and least heterozygous plants during inbreeding to isolate useful genes and superior partially inbred parental lines. A reduction of heterozygousity was found in the S1 progenies for all other families except for family TMS 98/0002 which recorded the highest missing data. The result further indicated that over 55% of the progenies had heterozygousity values less than 25%. This implied that there were good materials to carry to the second generation of inbreeding which probably will reduce heterozygousity in the next breeding generation.
