 ABSTRACT

The present investigation was undertaken with a view to generate genetic information on gene effects for oil content in Castor (Ricinus communis L.). The experimental materials consisted of twelve generations namely P1, P2, F1, F2, B1, B2, B11, B12, B21, B22, B1s and B2s of four crosses of castor viz., JP 104 x JI 433 (cross 1), SKP 84 x JI 433 (cross 2), SKP 84 x JI 437  (cross 3) and SKP 84 x JI 441 (cross 4). Special scaling tests such as B, B12, B21, B1s and B2s were significant in all the four crosses besides significance of C, B11, B22 and X in cross 1; A, D, B11, B22, X and Y in cross 2; C, D and Y in cross 3; and C, B11, B22, X and Y in cross 4 showing the presence of epistasis. In ten parameter model, ‘m’, [h], [j], [y] and [z] were significant in all four crosses apart from significance of [i] and [x] in cross 1; [d], [l], [w] and [x] in cross 2; [d], [i] and [w] in cross 3; and [i], [l] and [x] in cross 4. The 𝜒2(3) value at two degrees of freedom for all four crosses were significant showing the presence of higher order epistasis and /or linkage.
