  The present study was carried out in five rice varieties viz. Pusa-1, Sugandha-4, Sugandha-5, Saket-4 and Saket-370, for analyzing the varietals differences during seed deterioration by subjected them to Accelerated Ageing (AA) at 45°C and 100% relative humidity (RH) for 24, 48, 72 and 96 h. Various physiological parameters such as moisture content, germination percentage, seedling vigour, vigour index and biochemical parameters such as reducing sugar based on DNS assay, soluble protein by Lowry’s method were explored. Different levels of seed vigor were obtained with different varieties and duration of accelerated aging treatments. Prolongation of ageing led to deterioration of both germinability and seed viability. The physiological results were coinciding with the biochemical parameters. Ageing conditions resulted in increased moisture content in all the varieties. The study concludes that accelerated ageing showed effect on seed quality of all the varieties of rice. All the test experiments performed concluded that Sugandha-4 is the best variety, followed by Saket-370 among all five varieties and Sugandha-5 and Saket-4 are highly sensitive varieties with respect to accelerated ageing.

  The present investigation is an attempt towards finding an effective sterilization protocol for two, field grown sugarcane varieties, CoS 88230 and CoS 767 from Meerut region and to establish the callus culture protocol. Four sterilizing agents EtOH, NaOCl, HgCl2 and H2O2 were used alone and in combination. Our finding suggests that the use of only one sterilizing agent is not successful for the sterilization of leaf sheath explant of sugarcane. HgCl2 (0.1%) for 5 min and EtOH (90%) for 10 min was found best when used along with prior washing and surface sterilization with 20 and bavistin. An increased response of callus initiation was achieved on MS medium supplemented with 2,4-D (1 mg L-1) and antibiotic amoxicillin (2 mL L -1). present research attempt will allow mass multiplication of economically important sugarcane varieties through tissue culture technology can be used further to complete the demand of farmer for the planting material of the genetically superiors sugarcane varieties.
