ABSTRACT
The field experiment was conducted at Philippine Rice Institute (PhilRice), located at Maligaya Munoz Nueva Ecija, Phillippines. Rice ratooning ability under 10, 20 and 30 cm stubble cutting heights was evaluated on the basis of basal and nodal tillers regeneration, missing hills, ratoon vigor and rating and grain yield. Out of 30 varieties /lines tested only PSBRc8, PSBRc6 and BPIRi10 showed ratooning potentiality in terms of ratoon vigour and rating, basal and nodal tillers regeneration and final grain yield at lower stubble cutting height of 10 cm. It is recommended that for higher ratoon grain yield cutting of stubbles at the 10 cm should be performed.
