ABSTRACT: The objectives of this study were to identify the the 53 evaluated, with the presence of two alleles per locus. genetic variability and estimate the level of homozygosity in a Allele frequencies varied between 0.71 and 0.53, and the PIC, castor bean F4 population using microsatellite markers (SSR). between 0.32 and 0.37.
The average observed heterozygosity To this end, it was performed the genotyping of the population H o (0.30) was lower than the expected heterozygosity H e (0.47). through 53 pairs of SSR primers.
Allele frequencies were estimated Five dissimilar groups were formed, showing that there is genetic by number of alleles per locus, expected heterozygosity (H e), variability among the evaluated genotypes.
The highest genetic obse...
