ABSTRACT
Comparative effects of four treatments 60 ppm GA3, 40 ppm GA3, 60 ppm Mangiferin and 40 ppm Mangiferin along with control were tested on seed production aspects of four cyto-sterile line viz., IR 58025A, PMS 2A, PMS 3A and PMS 10A. It was observed that all the treatments scored much higher values than control for the characters like duration of florets opening, angle of florets opening, exserted stigma, panicle exsertion, grain yield per ha etc. Cyto-sterile line PMS 10A, PMS 3A and PMS 2A possessed better important floral traits than IR 58025A. However, cyto-sterile line IR 58025A scored much higher values for seed grain yield per ha, spikelet length and plant height.
Key words :
CMS lines, Cyto-sterile line, GA3, Hybrid seed production, Mangiferin, Rice, Yield parameters.
