Abstract

Identification of Gilkworm genetic stocks of each country and their potential have large imprtace.Due to lack of sufficient information about the three commercial silkworm pure lines of 31, 103 and 107 under Iranian condition, this research was conducted to assess the effects of gender, GENERATION and line on cocoon economical TRAITs. Phenotypic data for these three lines was collected from Iran Silkworm Research Center (ISRC) in three GENERATIONs since 2001-2003.The used data included eight families ´ 3 × GENERATIONs ´ 3 pure lines ´ 3 TRAITs ´ 2 gender ´ 25 individuals (equals to 10, 800 records). Mean comparisons were conducted for each line, GENERATION and gender in total and each pure line separately. Fixed effects of pure line, GENERATION and gender were significant in level 0.01 for cocoon weight, cocoon shell weight and cocoon shell percentage (P<0.01). TRAIT average of three pure lines were statistically significant difference (P<0.05); so that the average of cocoon weight and shell cocoon weight for pure line of 31 (1.60±0.28 gram and 0.35±0.05 gram) and pure line of 103 (1.62±0.28 gram and 0.36±0.05 gram) were more than pure line of 107 (1.39±0.21gram and 0.28±0.03 grams), but shell cocoon percentage mean in pure line of 103 (22.76±2.75 gram) was more compared to the other pure lines. This TRAIT for pure line of 107 was less then other pure lines (20.90±2.31 gram). In total pure lines of 31 and 103 had most quantitative TRAITs pure line of 107 had less quantitative TRAITs. GENERATION effect on differences between the cocoon weight, cocoon shell weight and cocoon shell percentage was significant (P<0.05). Second GENERATION in comparison to other GENERATIONs had more cocoon weight (1.648 gram) and cocoon shell weight (0.353 gram), but the average of cocoon shell parcentage (%21.651) was minimum compared previous and next GENERATIONs (P<0.05). Also cocoon weight, cocoon shell weight and cocoon shell percentage were significantly different in two gender of female and male. Cocoon weight and cocoon shell weight of female individuals were higher than male individuals (P<0.05).
