Mathematical prognosis at choice of ameiotic parthenoclones and genetically sex-limited at larva stage silkworm Bombyx mori L. lines for industrial hybridization. Bulg. J. Agric. Sci., 11: 633-637
Study on possibilities of mathematical prognostication at selection of F1 Bombyx mori L. hybrids of female individuals from ameiotic parthenoclones and male ones from genetically sex-limited at larva stage lines have been carried out at Regional Centre for Scientific-Applied Service - Vratza.
It was determined that used model for mathematical forecasting through selection indices allow us to establish particular selection programs, increase the efficiency and accelerate the speed of genetic progress at creation of new high heterozygous F1 silkworm hybrids of "parthenoclone x line" type for industrial cocoon production.
E11 x Vratza2003, Parthenoclone2 x Vratza2003, Parthenoclone2 xVratza2012 and E11 x Vratza2012 were the most perspective F1 silkworm hybrids
