Symbol	Chr.No	Map	Name	Explanation	Allele
Ac	3	?	Abnormal corselet	Gene affecting formation of dorsal region in thoracic segment.X-ray induced;fissure along dorsal median line of first and second thoracic segments, homo-lethal.
al	5	37.9	albino	Gene affecting harding of cuticle at the first ecdysis.Spontaneous;homozygotes hatch and develop normally during first instar, distinct albino features appear soon after first ecdysis and die with shrinking; cuticle layer incomplete in hardening and have porous structure, unable to eat leaves and to maintain body-water: Independent spontaneous mutation al², like al but time of death variable.	al²
ap	3	22.3	apodal	Gene affecting formation of thoracic legs.Spontaneous;thoracic legs degenerated, larvae have difficulty in creeping and feeding; female moth sterile due to abnormal differentiation or degeneration of bursa copulatrix; male moth fertile but cannot copulate unaided.
bd	9	22.9	dilute black	Gene affecting lawal body color (balck) and fertility of Imago.Spontaneous;larval body grayish black; moths have difficulty in getting out of cocoons, females sterile producing eggs whose micropilar structures are abnormal, males fertile but cannot copulate unaided: bd^SW (chimney sweep) similar: Female fertility and copulation of male good in bd¹(dilute black fertile).	bd' , bd^f , bd^Sw
bl	15	0	blind	Gene affecting formation of eye spots on the second thoracic segment.Spontaneous;eyes spots on the second thoracic segment solid black.
Bo	11	28.8	Bamboo	Gene affecting hardness of skin, formation of larval markings and scale for moth.Spontaneous;abdomen of larva compact and hard, bulges appear at posterior margin of each segment, thorax stout; inhibits eyespots and crescents; scales on the back of moth poor: mortality high when homozygous.
Bs			Brown spot	Gene affecting brown spots of larval skin.Spontaneous;pairs of brown spots appear on each segment just after molting due to excretes of exuvial gland.
Bt	1	40.8	Beet feader	Gene affecting laraval feeding XXXXX, wide feeding range.X-ray induced;larvae unable to discriminate mulberry leaves from others, dominance incomplete.
bts	17	36.4	brown head and tail spot	Gene affecting pigmentation of cuticle in head, legs and anal plates.Spontaneous;head cuticle and anal plates pigmented reddish brown after third or fourth instar: bts² similar.	bts²
Bu	11	30.9	Burnt	Gene for formation of dorsal midline region from fifth to eight segment.X-ray induced;burn-like scar on dorsal midline from fifth to eighth segment, dorsal vessel widened; homozygotes die as embryos with incomplete formation of dosal amnion and midgut, navel remained open.
cal	7	？	susceptibility to muscardines	Gene relating to susceptibility of fungas diseases (muscardine).Spontaneous;susceptible to muscardine fungus diseases; locates in vicinity of q.
ch	13	9.6	chocolate	Gene affecting larval skin color.Spontaneous;larval skin as well as head cuticle of newly hatched larvae reddish brown, in grown larvae markings and sieve plates of spiracles remain reddish brown: ch^p(chocolate purple) like ch but reddish color lighter. See also Ia and sch.	ch^p
ch-2	18	0	chocolate 2	Gene affecting larval skin color.Spontaneous;body-color of newly hatched larvae dark reddish brown.
cm	20	41.9	maternal chocolate	Gene controlling skin color of new hatched larva.Spontaneous;newly hatched larvae from eggs laid by homozygous mother pale-reddish brown irrespective of their own genotype, feeding third instar, less conspicuous in grown larvae; homozygotes die as embryos: Gl^R (Glossy retarded) larvae reddish brown and lustrous at every molting stage, body spindle shaped; homo-lethal.
cot	15	25	contracticle	Gene affecting body shape and reactivity for outer stimulation.Spontaneous;larvae stout; when touched softly contract body by two-thirds and fall down vomiting gut juice, stay still for a while; moths hold wings upwards and fall down on touch, difficult to copulate. See also sol.
cts	16	4.6	cheek and tail spots	Gene affecting color in head and dorsal region of anal leg.Spontaneous;chocolate-colored spots on both sides of head cuticle and on anal plates in the last larval instar, but not manifested when young.
Df-t	20	11	Tsujita's dwarf	Gene affecting body size.γ-ray induced;larval growth retarded, homozygotes die as embryos; significantly reduce crossing over frequencies, might be accompanied with chromosomal aberration.
Di	14	43.2	Dirty	Gene affecting larval marking pattern.Spontaneous;irregular dark brown lines and dots cover the body surface, regions of crescents and star spots lack pigment hence remained as white patterns on blackish background when homozygous; combined with p no pigment on the skin. See also U.
Dus	10	3.9	Star　spots duplication	Gene controlling star spots in larval.Spontaneous;a pair of additional star spots on ninth segment, penetrance low; homozygotes die as embryos lacking head capsule.
dw-k	10	0	dwarf-k	Gene affecting larval development XXXX young larval stages.Spontaneous;larvae slow growing and dwarf.
