Oryza barthii has candidature for some significant economic traits but its utilization in rice breeding is rare. This study traced introgression of heritable traits in the offspring of O. barthii with an Africa-Asian progenitor to F8 and assessed diversity between the parents and the F8 population. Significant (P<0.05) genotypic variation existed for some traits. Grains per panicle and days to 50% flowering had respective least (3.34%) and highest (96.32%) broad sense heritability. Genotypic Coefficient of Variation (GCV) was lower than Phenotypic Coefficient of Variation (PCV) in all traits. Grains per panicle and tiller number had respective least (5.28% and 8.05%) and highest (90.8% and 98.1%) GCV and PCV. Progenies significantly differ in panicles and grains sizes, shapes, colours, presence or absence of awns. Five principal components explained 80.1% of the total variance. Plant height at maturity was the only trait with significant (p ≤ 0.01) correlation and regression between F6 and F7. Progenies resemblance to P1 retrogressively declined while offspring similarity to P2 progressively increased from F6 to F8. The present diversity study discovered three heterotic groups: the O. barthii (11%), O. sativa (67%) and the intermediate group (22%). This research has added to rice genetic resources, making investigation of the nutritional status of the different progenies interesting research for further studies.
