Description |
Field and laboratory experiments were conducted to study the effect of seed invigoration on synchrony and storage potentiality of parental lines of sunflower hybrid RSFH-1 at the Main Agricultural Research Station and Laboratory studies in the Department of Seed Science and Technology, College of Agriculture, University of Agricultural Sciences, Dharwad – 580 005 during kharif season of 2005-06. The results of the field experiment revealed that, (RH64NB) male parental seeds invigorated with GA3 50 ppm showed significantly higher field emergence, plant height, leaf area index, lesser number of days to initiation of flowering, days to 50 per cent flowering, maximum capitulum diameter, higher seed set, seed yield per plant and seed yield per ha (802.0 kg) in female parent (CMS 103A), but no significant differences were noticed among seed quality parameters. The urea (2%) spray at button initiation stage resulted in maximum plant height, leaf area index, lesser number of days to initiation of flowering, days to 50 per cent flowering, maximum capitulum diameter, higher seed set, seed yield per plant and seed yield per ha (794.0 kg) but seed quality parameters were non-significant. The interaction between seed invigouration and urea spray showed non-significant difference on plant growth, seed yield and seed quality parameters. However, perfect synchrony between parental lines and more hybrid seed yield were noticed with male seed invigorated with GA3 50 ppm followed by spraying of urea (2%) to the restorer line at button stage. The storage experiment involving female (CMS-103A) and male (R-64NB) parental seeds of sunflower hybrid RSFH-1, revealed that among seed invigoration treatment ıtocopherol (2%) found relatively better in maintaining higher germination and seedling vigour with low EC and lower lipid peroxidation value up to eight months of storage in both parental line. |
