Abstract
Heterobeltiosis (relative to better parental variety) and standard het erosis (relative to standard variety) for 10 larval and cocoon quantit ative traits among the hybrids between five multivotine and three bivo ltine strains of silkworm, Bombyx mori L., were estimated. The results indicated that the hybrids between multivoltine females and bivoltine males gave higher heterosis than their reciprocals. Variance due to g eneral and specific combining ability and the genetic components were also estimated. The role of gene actions governing the different trait s studied is discussed.
