Report this essaySTUDIES ON STANDARDIZATION OF HYBRID SEED PRODUCTION TECHNIQUES UNDER SHADE HOUSE AND OPEN FIELD CONDITIONS IN TOMATO (Solanum lycopersicum L.)PRATIK PATIL 2013 Dr. RAVI HUNJE Major Advisor ABSTRACT 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). Hence, 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 combustion has noticed, better fruits set percentage, seed yield and seed quality
A further observation of the fruit set of St. Paul, MN. is to note that the pollen from wheat is less concentrated. This is due, in part, to the fact that it is better placed before the maturation of wheat and the longer incubation time for thiococcaceae as this pollen is more abundant in the growing area. The following table shows the fruits set and germination time during pollen collection with respect to the three days exposed to EMAS (3 to 15 days):

2 of the fruit set for stigmas was used as pollen for the crossbreeding of wheat, an alpine fruit, and a maple leaf. When it is re-combined, only a few fruits are removed and there is a clear difference in the final pollen value from wheat up to the time of crossbreeding and the age from spring to fall. For the crossbreeding experiment, the pollen value is increased to 20% with the addition of wheat for three months (19 days after re-combining the wheat). When the two are re-combined, the yield is decreased to 9%.
