COMBINING ABILITY FOR SEED YIELD AND ITS COMPONENTS IN PAPAVER SOMNIFERUM L.

Published on

Line x tester analysis involving 4 male and 31 female parents in opium poppy (Papaver
somniferumL.) alongwith their Flhybrids was carried out in four environments. The results
indicated that both general and specific combining abilities were important in the
expression of seed yield and its components, viz., husk yield, plant height, stem diameter,
and leaf area index. However, nonadditive components of genetic variances was
predominant. The parent varieties MOP 3, MOP 379, MOP 319, Ie 7 and IC 128 were good
general combiners for seed and husk yield, the latter two parents also extended their good
general combiningability to stem diameter. The bestspecific crosscombinations were NOP
1 x IC 42, IC 19 X MOP 3 for seed yield and leaf area index, and MOP 539 X JA 16, IC 7 X
MOP 3 for seed and husk yield.
