Effect of nipping axillary flower buds on seed yield and yield components in RHA·274
(restorer) line ofsunflowerwasinvestigated. Generally, the nipped plantshad higher mean
values for the characters studied. Seed yield increased by 26.3% in the nipped plants over
the normallybranched plants mainly due to increased loo-seed weight. However,increased
seed yield in the nipped plants was compensated by increased oil content in the branched
plants, thus maintaining the same oil yield per plant in both nipped and branched plants.
The significance ofinducing plants to produce monoheads artificially is discussed in view
of the seed production programmes.
Keywords: Nipping, sunflower, axillary flowers, seed yield, oil yield.
