Evaluation of Bivoltine Silkworm Breeds of Bombyx mori L. under West Bengal Conditions
The Indian sericulture industry is beset with many problems. One of the main problems is the inability to produce quality silk of international grade. The quality silk can be produced only form bivoltines. The bulk of silk produced in India is from Multivoltines which are of inferior quality. Therefore, it is highly pertinent to have more productive bivoltine silkworm breeds capable of producin...
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 کاملBotanicals against Nuclear Polyhedrosis Virus infecting three breeds of mulberry silkworm, Bombyx mori L
Mulberry silkworm, Bombyx mori L, most valued for silk and other medicinal products is prone to various biotic stresses among which the disease caused by Nuclear Polyhedrosis Virus (BmNPV) is most serious as it occurs throughout the year causing losses to the tune of 30-40 per cent. Studies conducted on eco friendly management of the disease using botanicals revealed that 800 ppm hexane leaf ex...
متن کاملPerformance of Six Bivoltine Bombyx mori (Lepidoptera: Bombycidae) Silkworm Strains in Kenya
The economic and field performance of six Bombyx mori Linnaeus bivoltine strains were evaluated, namely ICIPE I, Chun-Lei X ZhengZhu (C X Z), QuiFeng X BaiYu (Q X B), Quingsong X Haoyoe (Q X H), Suju X Minghu (S X M) and 75xin X 7532 (75xin). Performance was based on larval, cocoon, pupa and shell weights, relationship of food consumption to larval weight, cocoon weight and shell weight. ICIPE ...
