Fig. 1
Mother and son inbreeding scheme in T lineage: 10 females were taken from the stock culture and reared them to produce F1 progeny. Then, 30 F1 virgin females were reared to produce son and when the son became an adult; both mother and son were confined in the same tube for 48 h. The male was removed from the tube after 48 h and its mother kept reared on tobacco leaf discs and named as the F1 generation. Since then, F1 female allowed to produce a son to continue the F2 mother and son inbreeding and similar procedures were used with F1 inbreeding line
