Abstract:
In the present study, an evaluation of four quantitative characters viz. Yield/100 dfls, SR%, Denier, and Reel ability of Cocoons produced by Silkworm through analysis of variance was carried out. Eighteen varieties of mulberry silkworm, Bombyx mori L. were used in this analysis viz., Nistid white(P), ISK, D× C, BN(P), BN-(P)m, BN(M)M, N(I)M, N(I) K(M), N(I)K(P), N(I)K(P)L, NN7B-P, NN7B-M, MBY-0115 (P), BSR 3 Yellow(p), BSR-3 Yellow (m), BSR-10 yellow(m), BSR-1 white(m) and BSR-1 white(p). Analysis of variances conducted on the results indicated that the varieties differ significantly (P < 0.01) in respect of some characters studied to identify the existence of real differences among the varieties through analytical observation. The good performing varieties were ISK, D×C, BN (P), BN-(M)M, N (I)M, N(I) K(P), N(I) K(P) EL, NN7B(M), BSR-1White-(M), BSR-1White-(P) in most cases. But the most superior variety was N (I) M, because it showed the highest performances in both cases of denier and reel ability which were the most expected characters in this investigation. The other eight varieties showed poor performances. From the finding of the present investigation, it is recommended that the varieties ISK, D×C, BN(P), BN-(M)M, N (I)M, N(I)K(P), N(I)K(P) EL, NN7B(M), BSR-1White-(M), BSR-1White-(P) could be exploited for commercial silk production following rearing technique.
