摘要

Mulberry is the primary host plant of silkworm, Bombyx mori L. which is exploited on commercial scale for production of silk in the country. Many feeding trials with different races of B. mori have been conducted to select and recommend the suitablecultivars of mulberry for the rearing of region specific races of silkworm (Bheemanna et al., 1997; Koul et al., 1977; Verma and Kushwaha, 1970; Mishra, 1995; Verma, 1998). The literature on the suitability of mulberry varieties in the region of Uttaranchal is lacking and this appears to be one of the reasons for the factual recommendation of mulberry varieties for the development of sericulture. With this objective, the present investigation was undertaken to study the growth and development of two popular bivoltine races of B. mori viz., NB_4D_2 and SH6 on 5 varieties of mulberry viz., CM, TR-8, K-2, S-54 and S-41.
