Abstract: 

Variance and Covariance components, heritability and genetic correlation of economic traits in hybrids of six lines of Silkworm were estimated. In all hybrids, cocoon weight heritability was superior then cocoon shell weight heritability. Heritability of cocoon shell percentage was lower then other traits. There was a height positive genetic correlation between cocoon weight and cocoon shell weight and there was low genetic correlation between cocoon weight and cocoon shell percentage too. Heterosis effect on means of cocoon weight and cocoon shell weight was positive and increase in heterosis percentage increased means of this traits. With increase in recombination percentage in cocoon shell percentage, mean of this trait increased. The results showed that there was an inverse relationship between Heterosis and recombination effects. Also genetic gain and means of triats in 151, 152 and their hybrids, were upper than others. So it is expected that the use of these liens is better in commercial level.
