COMBINING ABILITY FOR PHYSIOLOGICAL CHARACTERS AND OPIUM YIELD IN OPIUM POppy (PAPAVER SOMNIFERUM L.)

Published on

The combining ability analysis was worked out in Fl and F2 generations ol 8 x 8 parents
half diallel lor physiological characters and opium yield in opium poppy. Results revealed
that both additive and nonadditive genetic components ol variance governed the
expression olopium yield and physiological characters studied, lormer being predominant
in both the generations. Among the varieties, MOP 539 lor opium yield, harvest index, days
to 50% flowering, leal area and leal area index and MOP 507 lor opium yield, biological
yield, NBPGR 1 lor opium yield and early flowering and NOP 4 lor harvest index appeared
to be good general combiners. They can be used as donors in future breedinglorhigh opium
yield with ellicient harvest index. In respect ol specilic combining ability, crosses MOP
539 x NOP 4, NBPGR 1 x NBRI 3, and NOP 4 x VO 185 showed best cross combinations lor
opium yield with harvest index.
