Paper Title:
Heterosis and combining ability for weight of mature larvae and filament length of fifteen hybrids raised by half(6*6) daillel cross in silkworm Bombyx mori.L.
ABSTRACT:
The investigation was carried out to evaluate fifteen hybrids raised by half (6 × 6) diallel cross involving six silkworm varieties of Bombyx mori viz. B(I)J, BB(O), N(I)K(P), BN(mn)M, HTHRB-3 and 95/14 in order to estimates of heterosis and combining ability. Observations were made on two economically important traits namely; weight of mature larvae and filament length over four rearing seasons in Bangladesh. Considerable amount to heterosis was obtained in the crosses where parents BB(O), B(I)J and HTHRB-3 were involved in different seasons. The gca quantities of the parents varied from season to season. The parents exhibit a significant gca effect for majority of the characters in all the rearing seasons. The overall gca quantities confirmed that the developed varieties B(I)J, BB(O) and HTHRB-3 and were the best general combining parents. It is evident from the results that cross 4, “B(I)J×HTHRB-3” and cross 8, “BB(O)×HTHRB-3” exhibited the best performance.
