Dubey, Shama Shukla, S. Singh Opium poppy belongs to the family − ‘Papaveraceae’ and is well known mainly for its pharmaceutically important alkaloids and seeds. In order to delineate the gene-effects conditioning the expression of seed yield and straw alkaloids, six crosses viz. IS 14×Sampada, I 14×Mtu, Sampada×Sujata, CIM Ajay×Dfr 44, Sapna×Sanchita and SPS 49×TS 1 involving the eleven parents, were sampled for P1, P2 and F1 (=P1×P2) non segregating, and F2 (=F1), BCP1 (=F1×P1), and BCP2 (=F1×P2) segregating generations. The days to flowering (50%) and plant height showed all the three type of interactions (i, j, l) in three crosses, namely C1 − IS 14×Sampada and C2 − I 14×Mtu but the traits peduncle length, codeine and thebaine content showed in other three crosses as C1 − IS 14×Sampada,C2 − I 14×Mtu,C3 − Sampada×Sujata and C4 − CIM Ajay×Dfr 44 in order. The two type of interactions additive×additive and additive×dominance interactions (i, j,) exhibited by the C6 − SPS 49×TS 1 for plant height and thebaine content, C5 − Sapna×Sanchita for peduncle length, codeine and narcotine content. The genetic basis of character expression indicated that the interacting crosses showing non-allelic interactions particularly duplicate epistasis in most of the...
