COMBINING ABILITY ANALYSIS FOR HARVEST INDEX, SEED YIELD AND IMPORTANT COMPONENT CHARACTERS IN OPIUM POPPY (PAPAVER SOMNIFERUM L.)

Published on

Genetics of harvest index, seed yield and other components was studied following 8 x 8
half diallel analysis in Fl and F2 generations of opium poppy. Combining ability analysis
showed both additive and nonadditive type of gene action playing significant role in
controlling the expression of all the characters studied. Number of capsules/plant, capsule
weight, leaves/plant, and seed yield were predominantly under the control of nonadditive
gene action in Fl generation. Harvest index, husk yield and capsule diameter were
predominantly under control of additive type of gene action in both the generations and
capsule weight in F2 generation. The best general combining parents were IC 128 for seed
yield and VO 185 and NBRI 3 for harvest index. MOP 539 x NBPGR 1, MOP 507 x NBPGR
1, IC 128 x VO 185 and NOP 4 x VO 185 showed good specific cross combinations for high
seed yield and high harvest index.
