Abstract

In the present investigation, 18 Fl hybrids in Oryza sativa L. were studied for their ratooning ability. The results of scaling tests revealed the presence of epistasis. Partial dominance was prevailing in majority of the crosses. Inbreeding depression was low. Moderate to fairly high degree of heritability (50.2% to 81.2%) and genetic advance (9.30/. to 29.8%) were observed. Most of the crosses showed additive (d) and additive Xadditive (iHypes of gene effects. Thus, the ratooning ability is governed by additive gene action.
