Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences


This article reveals the results of the analysis conducted in 2018-2020 on the economical traits of F1 hybrid combinations obtained with the participation of C8 ngl and common lines and breeds balanced on l1 and l2 lethal genes which are located on the Z chromosome of mulberry silkworm. The male hybrids have a number of advantages over bisexual hybrids in terms of viability and silk fiber quality. In particular, in the combinations L-66xC-8 ngl.
