HETEROSIS FOR YIELD AND YIELD CONTRIBUTING CHARACTERS IN SAFFLOWER (CARTHAMUS TINCTORIUS L.)

Published on

High heterosis over better parents was recorded in 32 hybrids pooled over three
environments for yield and its components in safflower. The hybrids exhibited the
maximum heterosis for seed yield/plant followed byseeds/capitulum on secondarybranch,
secondary branches/plant and seeds/capitulum on primary branch. Highest value of
heterosis over better parent (92.3"10) was recorded for seed yield/plant in the hybrid MS-l X
NS-I016. In general, hybrids derived from genic male sterile lines gave better performance
for seed yield and other characters.
