Effect of pollination time and crossing ratio on fruit set and seed yield of brinjal (Solanum melongena L.) hybrid in middle Gujarat

Abstract

Flowering and fruit set are two most important factors
determining the seed yield of cultivated brinjal. An
investigation was carried out to find the effect of different
pollination time and female to male flower crossing ratios on
fruit set and seed yield parameters of brinjal hybrid seed
production. The experiment result revealed that different
pollination time and crossing ratios had significant effect
on seed quality parameters. Among the different pollination
time, pollination at 9.00 to 11.00 am recorded significantly
higher fruit set per cent (64.53%) with higher number of fruit
set per plant (9.64) fruit weight (342.9 g), fruit length (39.95
cm), fruit girth (15.92 cm), mature fruit yield per plant (3274.9
g), seed yield per plant (23.99 g), number of seeds per fruit
(425.5), seed weight per fruit (2.47 g) and 1000 seed weight
(5.61 g) in compared to other pollination times irrespective
of time of pollination, crossing of four female flowers with
one male flower (4:1) recorded significantly higher fruit set
per cent (66.17%), number of fruit set per plant (10.22), fruit
weight (345.7 g), fruit length (40.89 cm), fruit girth (16.14
cm), mature fruit yield per plant (3486.3 g), seed yield per
plant (26.44 g), number of seeds per fruit (475.8), seed weight
per fruit (2.71 g) and 1000 seed weight (5.72 g) compared to
other crossing ratios in seed parent of brinjal hybrid seed
production.
