    Combining ability in pigeonpea (Cajanus cajan [L.] millsp)
    (Kerala Agricultural University, 1996) Achamma Oommen; Namboodiri, K M N; Vijayakumar, N K
    Even though both additive and nonadditive gene effects were found to be important in the expression of the characters studied, the additive gene effects were having more influence than nonadditive gene effects. Number of primary branches was determined by additive and nonadditive genes, whereas number of secondary branches was influenced by additive genes. All the other nine characters were determined by additive genes. Among the five parents studied, PLA 550 was the best general combiner and among the crosses UPAS 120 x 1C 15708 was having good sea for all the characters.

    Genetic analysis of yield and yield components in pigeonpea (Cajanus Cajan (L.) Mill sp.
    (Kerala Agricultural University, 1999) Achamma Oommen; Namboodiri, K M N; Unnithan, V K G
    Generation mean analysis carried out in pigeonpea to estimate gene effects revealed that, yield and yield components AK under all the three types of gene action. v\/.-, additive, dominance and epistasis. Hence reciprocal recurrent selection seems to be the best suited method of breeding for improvement of this crop.
