No. 566] INHERITANCE IN EARS OF MAIZE 97 



That the male gametes of variegated- eared maize do 

 often carry factors for self -red is shown by crosses of 

 pure non-red strains with pollen from plants with varie- 

 gated ears. The plants that furnished the pollen for 

 these crosses were in some cases the same ones whose self- 

 pollinated ears were concerned in the records discussed 

 above. The results of these crosses are summarized here. 

 Eight non-red ears crossed by plants that were homozy- 

 gous for pericarp color yielded 17 red-eared, 116 varie- 

 gated-eared and 8 white-eared 8 plants. Similarly, 14 ears 

 of pure non-red strains crossed by pollen from plants 

 heterozygous for pericarp color yielded 26 red-eared, 192 

 variegated-eared and 229 white-eared plants. Consider- 

 ing merely the plants with colored ears, 22 crossed ears 

 produced 43 red-eared to 308 variegated-eared plants, or 

 a little over 12 per cent, self-red. 



Since the male gametes of variegated-eared corn have 

 now been shown occasionally to carry a factor for self- 

 red, it is obvious that only from crosses of variegated- 

 eared plants with pollen from pure non-colored strains, 

 can a definite idea of the inheritance of the somatic varia- 

 tions in pericarp color be gained. 9 Twelve ears from 

 homozygous, variegated plants cross-pollinated by non- 

 red strains might have afforded important evidence, but 

 for the fact that 7 of them contained only narrow-striped 

 grains and the other 5 no fully or even nearly self-red 

 grains. The results are summarized here:
