Effect of Salicylic Acid on Commercial Traits of the Bivoltine Crossbreed Races of the Silkworm, Bombyx mori L.
Topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine CSR2, CSR4 and CSR2XCSR4 crossbreed races of the silkworm, Bombyx mori L. The results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoo...
متن کاملAn analysis of genetic variation and divergence in Indian tropical polyvoltine silkworm (Bombyx mori L.) genotypes
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 reveal...
متن کاملScreening Strains of the Mulberry Silkworm, Bombyx mori, for Thermotolerance
A tropical climate prevails in most of the sericultural areas in India, where temperature increases during the summer lead to adverse effects on temperate bivoltine silkworm rearing and cause crop losses. Screening for thermotolerance in the silkworm, Bombyxmori L. (Lepidoptera: Bombycidae) is an essential prerequisite for the development of thermotolerant breeds/hybrids. In the current study, ...

15 صفحه اولInbreeding Effects on Quantitative Traits in Random Mating and Selected Populations of the Mulberry Silkworm, Bombyx mori
The objective of the present study was to estimate the level of inbreeding coefficient during inbreeding of the pedigree of random mating and selected populations of two distinct races of mulberry silkworm, Bombyx mori (Lepidoptera: Bombycidae), in the silkworm germplasm. The six generation data of the two races, namely multivoltine Pure Mysore and bivoltine NB4D2, were studied for inbreeding d...
