材料与方法本研究家蚕品系分别为Twl（白色蚕卵，普通蚕卵；+ re/+ re, w2/w2, p/p）和re9（红色蚕卵，条纹蚕卵；re/re,+ w2/+ w2, PS/PS）； Tw1与re9杂交的F1蚕卵颜色正常（黑色）。F2的蛋色离析为黑：红：白= 9:3:4，与re9的回交为黑：红= 1:1（图1-4）。根据TAKIZAWA和TAMAZAWA（1968）的方法诱导四倍体家蚕，即在沉积后105 ~ 135分钟的一组卵
MATERIALS and METHODSThe strains of the silkworm, Bombyx mori, used in the present study are Twl (white egg, plain silkworm;+ re/+ re, w2/w2, p/p) and re9 (red egg, striped silkworm; re/re,+ w2/+ w2, PS/PS) F1 eggs of the cross Tw1 x re9 show normal color (black). Egg-color segregation of F2 is black: red: white= 9: 3: 4, and that in the back cross with re9 is black: red= 1: 1 (Figs. 1-4).-Tetraploid silkworms were induced according to the method of TAKIZAWA and TAMAZAWA (1968), that is, a group of eggs at 105 to 135 minutes after deposition
