An experiment was conducted to study the effect of
female and male flower crossing ratios on fruitset (%), seed
set, seed yield per fruit and seed quality in tomato cv. Arka
Abhijit at Indian Institute of Horticultural Research,
Bengalury. The results indicated that there were no significant
effects of female to male flower crossing ratios namely, 3:1,
4:1 and 5:1 on seed yield attributes namely, fruitset (%),
number of seeds per fruit, seed weight per fruit and 100-seed
weight except for higher mean percent fruitset in 4:1 ratio
(66) and higher number of seeds per fruit ( 197.4 ) in 3:1 ratio
in the year 2005. However, the female to male crossing ratio
of 5:1 resulted in significant increase in hybrid seed quality
for the characters seed germination (65.50 % and 74.81%)
and seedling vigour index (based on I and II count) of 1 483
and 1689 respectively in tomato. Hence, in hybrid seed
production of Arka Abhijit, pollen scarcity and quantity was
not found to be a limiting factor and could accommodate
crossing up to 5:1 (female to male flower ratio) which pertains
to a pollen load of approximately 1866 pollen grains on
stigma without compromising on seed yield and quality.
