CORRELATION BETWEEN YIELD AND BIOCHEMICAL PARAMETERS IN THE MULBERRY SILKWORM, BOMBYX-MORI L

A detailed study was carried out on six biochemical parameters and fou r yield attributes using multiple regression analysis to investigate t heir relationship in the mulberry silkworm, Bombyx mori. The study gen erated new information on the importance of digestive amylase activity for the survival of the silkworm and revealed the inability of other enzymes to affect this relationship. Data also substantiate the observ ations made earlier on the genetic variability of amylase in the mulbe rry silkworm. Analyses extend the positive role of alkaline phosphatas e and invertase in the expression of the other yield traits studied an d indicate the definite possibility of using biochemical markers for s ilkworm breeding.
