the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...

Five Iranian native silkworm groups: Baghdad, Khorasan Orange, Guilan Orange, Khorasan Pink, Khorasan Lemon, and 107 and 110 commercial lines (12 families from each breed) were randomly selected and reared during 2003-2005 (five generations in spring and autumn). In each family, 30 male and 30 female cocoons were individually recorded for weight, shell weight and shell ratio. From among the nat...
Spirulina is blue-green micro algae. It contains 18 amino acids and vital vitamins like biotin, tocopherol, thiamine, riboflavin, niacin, folic acid, pyrodozoic acid, beta-carotene and vitamin B12 etc. These nutrients which are very easy to digest protein (biliprotein), carbohydrates (mucopolysaccharides, rhamnose and glycogen), 50 different minerals and trace minerals, beta-carotene, chlorophy...
The aim of this research was to estimate the variance components and genetic parameters for silkworm cocoon traits using univariate and multivariate models, and comparison of average productivity and resistance traits among three different selection strategies in two commercial silkworm lines of 153 and 154. Genetic parameters of cocoon weight, cocoon shell weight and cocoon shell percenta...
The effect of mulberry leaves enrichment with riboflavin in 7, 37, 77 and 127ppm concentrations on larval growth and cocoon characteristics of Bombyx mori L., hybrid 103×104 was studied. Silkworm larvae were fed on fresh mulberry leaves of shin inche nevise enriched with riboflavin once a day. All biological and economical parameters were determined by using standard techniques in sericulture. ...
abstract effect of selection index in four iranian commercial lines (107, 110, 153 and 154) on performance of their hybrids including 107 ×110, 110×107, 153×154 and 154×153 was investigated. selection index program was performed on all 3p commercial lines during 9 generations. next generation parents of 3p lines were selected in each generation, by construction of selection matrix based on heri...

the influence of moisture content of mulberry leaf on the growth, development and moisture build up in the body of silkworm was studied by feeding with different maturity leaves to late age of silkworm larvae. significantly higher larval moisture (79.78%), larval weight (65.65 g), pupal moisture (73.81%) was recorded in top tender leaf (high moisture) fed batches and least was recorded in the c...
