Description A field experiment was carried out at Hi-Tech Horticulture unit, Saidapur farm and
seed quality analysis at seed quality testing and research laboratory National Seed Project,
UAS Dharwad during 2012-13 to study the effect of growing conditions and plant spacing on
growth, seed yield and quality of tomato hybrid seed production and to know the pollen
viability of pollen parent and stigma receptivity of seed parent in hybrid seed production of
tomato Pusa hybrid-2 parental line under shade house.
The growing condition shade house registered significantly higher plant height at 90
DAT (186.54 cm), leaf area (131.75 dm2plant-1), leaf area index (4.32) more number of days
to 50 per cent flowering (36 days), days to fruit maturity (91.42 days), fruit set (67.6%), seed
yield per hectare (187.1kg), seed germination (92.5%) and seedling vigour index (1766).
Hance higher yield and quality of tomato hybrid seeds can be obtained under shade house
condition compared open condition
The spacing 60 x 60 cm recorded significantly higher number of fruit set (71.1%),
seed yield per plant (6.0 g), seed germination (92.3%) and seedling vigour index (1815) and
spacing 60 x 45 cm recorded significantly higher seed yield per hectare (170.6kg).
The significantly higher fruits set (67.68%), number of seeds per fruit (114.83),
germination percentage (92.40%), seed vigour index (1648) and seedling dry weight (5.50
mg-10) recorded when two day stored pollen is used for crossing and pollination two days
after emasculation of stigmas recorded significantly higher fruits set (67.68%), number of
seeds per fruit (114.83), germination (94.33%), seed vigour index (1760) and seedling dry
weight (5.86 mg-10).
Significantly higher Fruits set (75.2%), number of seeds per fruit (129), germination
(97.33%) and seed vigour index (1934) were recorded in treatment combination of two day
stored pollen used for pollination of two days after emasculated Stigma and this treatment
combustions better fruits set percentage, seed yield and seed quality
