Abstract


Sorghum (Sorghum bicolor [L.] Moench) is a cereal belonging to the family Poaceae. Sorghum is an important staple food crop in northern Nigeria. Most Sorghum varieties especially white endosperm coloured varieties have low pro-vitamin A (PVA) content compared to some yellow endosperm varieties leading to PVA malnutrition on populations who depend on them as a dietary source. Understanding the gene action involved in the inheritance of PVA will assist in providing a useful strategy for developing an efficient breeding methodology for selecting PVA traits in new sorghum genotypes to combat malnutrition in Nigeria. Six generations (P1, P2, F1, F2, BC1 and BC2) derived from two crosses (SAMSORG 17 × SAMSORG 44) and (SAMSORG 17 × SAMSORG 14) of sorghum were sown in a randomized complete block design with three replications in 2014 at the research field of the Institute for Agricultural Research (IAR) Samaru, of the  Ahmadu Bello University, Zaria, Nigeria. Generation mean analysis was employed to determine the genetic effects of PVA in sorghum.  The results of the analysis of variance showed that there was sufficient genetic variation for the PVA trait. The three-parameter genetic model and scaling tests (A, B, and C) revealed the inadequacy of the additive-dominance simple model to demonstrate the genetic mechanism controlling the trait as well as the presence of non-allelic interaction. However, the Hayman six parameters genetic model showed that additive genetic effect played a major role in the inheritance of PVA, while dominance and epistasis effects were also important although dominance effect was in the negative direction indicating duplicate type of epistasis for dominant decreasing alleles
