The choice of an efficient breeding procedure depends to a large extent on knowledge of the genetic system controlling the character to be selected. The objective of this study was to determine finger millet yield and yield components inheritance type and maternal effect existence and magnitude with analysis of generation mean. Ten generations (P1, P2, F1, F2, BC1 and BC2) and reciprocals (RF1, RF2, RBC1 and RBC2) developed from improved variety “Necho” x landrace “Tikur dagusa” cross. The results showed that, the presence of genetic variation for all traits. No significant differences were found for all the characters studied between F1, F2, BC1 and BC2 with their corresponding reciprocal generations; which indicating the absence of maternal effect. The scaling test and six parameter model predominantly self-pollinated crops like finger millet additive component of gene action are more useful for breeders for successful exploitation in the selection programme, by corresponding with additive x additive type of interaction effects and complementary type of epistasis. Hence, the types of inheritance found in the studied traits were both additive and non-additive gene effects. This suggest recurrent selection breeding method at early and later generations for the possibility of developing pure line and hybrid varieties of finger millet.
