Description A field experiment was conducted during Kharif, 2007 at Seed
Research and Technology Centre, Acharya N.G. Ranga Agricultural University,
Rajendranagar, Hyderabad to know the effect of pollination methods on seed
setting and seed quality of sunflower hybrid, NDSH-1. Experiment was conducted
in randomized complete block design in which different pollination methods were
imposed. Among different pollination methods, Bee pollination followed by hand
pollination on alternate days recorded the highest yield of 37.73 g/plant and 1152
kg/ha. Other yield attributing characters like number of filled seeds and seed set
percentage were also high in this treatment. Bee pollinated and hand pollinated
treatments (daily and alternate day) gave on par results in case of seed set
percentage, seed yield (g/plant) and number of filled seeds/capitulum. Highest 100
seed weight (11.43 g) was observed in Pollination in net covered plot. Seed quality parameters like oil content was more in Bee pollination
followed by hand pollination on alternate days. Bee pollinated treatments were
also recorded moderately high oil content compared to other treatments.
Germination percentage and seedling vigour index were also moderately high in
bee pollinated treatments. Dormancy duration was more (4 weeks) in Open
pollination and Pollination in net covered plot whereas, it was 3 weeks in all other
treatments.
Four species of honey bees - Apis mellifera, Apis cerana indica, Apis
dorsata, Trigona iridipennis were abundant on parental lines of sunflower hybrid,
NDSH-1. Their activity was influenced by weather parameters like temperature
and relative humidity.
By observing all these results, Bee pollination followed by hand pollination
on alternate days proved to be the best method both for yield and quality
parameters.
