Abstract

In order to study of variance components, HERITABILITY and genetic CORRELATION of some economic traits, were used collected data during 2004-2007 in hybrids of six LINEs of SILKWORM. In all hybrids, cocoon weight HERITABILITY was higher than cocoon shell weight’s HERITABILITY. HERITABILITY of cocoon shell percentage was lower than other traits. There was a high and positive genetic CORRELATION between cocoon weight and cocoon shell weight and there was a low genetic CORRELATION between cocoon weight and cocoon shell percentage. Heterosis effect on means of cocoon weight and cocoon shell weight was positive and increase in heterosis percentage increased means of this traits. Along 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 traits in 31, 32 and their hybrids were upper than others hybrids. So it is expected that the use of these liens is better in commercial level.
