3. The Sweet-Reid's Yelow Dent and the Raid's Yellow Dont-Boone 

 County White crosses which had the largest per cent, of suckered stalks 

 also showed the largest per cent, of twin ears and the smallest per cent, 

 of barren stalks. It may not be accepted that suckers are an indication 

 of prolificacy, but this series of experiments indicated as much. 



4. This being the third year of the experiment the constancy of 

 dominants and recessives would be expected to show itself. Sweet, red. 

 speckled, and white are supposed to be recessive to dent and yellow. In 



' 18 self-pollinated ears from sweet, 15 were pure sweet and 3 mixed white, 

 sweet, and yellow. In 12 ears from speckled seed, 9 were pure speckled. 

 2 pure yellow, and 1 pure red. In 15 ears from red seed, 13 were purr 

 red and 2 pure yellow. However, in none of the pollinations from white 

 seed was the percentage of pure ears so high. The highest being from the 

 white seed selected from the Sweet-Reid's Yellow Dent cross, in which 7 

 out of 12 ears were pure. 



In the experiments of 1908 yellow showed itself dominant to all other 

 colors, consequently it would contain not only the dominants but the 

 hybrids and such a condition manifested itself in the various selectloi 

 from yellow seed. A notable exception was from a row planted with 

 yellow seed from a twin ear. Every self-pollinated ear from this row 

 was pure yellow. 



5. From the Sweet-Reid's Y'ellow Dent cross two types arose, on?' 

 with whitish kernels and white cobs, like the original Stowell's Evergreen, 

 and the other with yellowish kernels and red cobs. These two types were 

 planted in 1011 on the grounds of the Horticultural Department, Purdue 

 University. The sea.son being backward the crop was not large, but 

 enough was obtained! to show that the ty]ies were lixed and would breed 

 true.
