The present investigation comprised 12 fodder sorghum varieties viz., HC-136, HC-171, HC-308, HJ-513, HJ-541, Pant Chari-7, GFS-5, Pant Chari-3, PC-5, SSV-84, CSV-15 and UP Chari-2 were used in the present study. The field experiment was conducted in Research Area of Forage Section, Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar during the year 2012-13 and accelerating aging test was conducted in laboratory of Department of Seed Science & Technology. The maximum seedling establishment per cent was found in HJ-513, SSV-84, HC-136 and CSV-15 which showed superiority almost for all the genotypes. The standard germination per cent and accelerated ageing test were found most suitable vigour parameters for prediction of seedling establishment in field conditions in relation to abiotic stress. The above superior listed genotypes had the maximum normal seedling establishment in laboratory for abiotic stress condition and its positive correlation with seedling establishment in field.
Key words: Sorghum, fodder, emergence, accelerating ageing
