An experiment was conducted in the year 2018 at ICAR-NRC on Litchi to investigate
the effect of different pollen grain sources on fruit set and fruit retention in
‘Bedana’ litchi. The enclosed flower panicles of ‘Bedana’ were hand pollinated
with male (M2) pollen from ‘Shahi’, ‘China’, ‘Rose Scented’, ‘SwarnaRoopa’ and
‘Bedana’ flowers. The current season’s pollen as well as one year old pollen stored
at 4 °C was used for pollination. The numbers of fruit set and fruit retention
per panicle were determined throughout the fruit development period starting
from pollination to harvest on a weekly basis. Initial fruit set was higher in all
cross-pollination with pollen sources ‘Shahi’, ‘China’ ‘Rose Scented’ and ‘Swarna
Roopa’ compared to self-pollination with pollen ‘Bedana’. The final fruit retention
in ‘Bedana’ was higher with all sources used for cross-pollination whereas there
was no fruit retention in self-pollination where “Bedana” was used as source of
pollen grains. Results indicated that cross-pollination in ‘Bedana’ litchi is essential
for fruit set and fruit retention. The limited number of initial fruit set resulted in
high retention of fruits (1.64% and 1.69%) in ‘Bedana’ with current season and
one year old pollen of ‘SwarnaRoopa’. It indicated that number of female flower
should be restricted in a panicle for further pollination which would ensure good
fruit retention at harvest.
