INHERITANCE IN SUGAR CANE. S7 



3. Like D-109 as to color but witli internodes and l>iids lik.' 



Crystallina. 



4. Like D-109 in shaj^e oi" internodes and buds, l)ut of a lighter 



color and very glaucous. 



5. Canes greenish-red to wine color, very little glaucousness. with 



buds more resembling those of Crystallina than D-IO!), and 

 with internodes intermediate between the two. 



6. AVith internodes like those of D-109, color likt' Crystallina. 



but larger in diameter than either. « 



7. With internodes and Inids like Crystallina, l)ut the color 



darker and somewhat like that of D-109. 



8. Like D-109 as to internodes and buds, but like Crystallina 



in color, 



9. Like D-109 in color but with large nodes, constricted inter- 



nodes and with buds somewhat like those of Crystallina. 



10. Like Crystallina as to buds and internodes but more glau- 

 cous. 



The following data concerning these canes were also noted: 



Number. Per cent. 



Total stools ,560 100 



Stools as red as D-109 147 28,3 



Stools darker than Crystallina 29-i 52, .5 



Stools having internodes like D-109 246 43. 9 



Stools having no eharaeter like D-109, and with color and inter- 

 nodes like CrystaUina 42 7. a 



These observations were made when the canes were quite mature, 

 so that there was the. least possible chance of subsequent change in 

 appearance; but cane varieties are extremely variable and their ap- 

 pearance' is affected in many ways by outside influences, such as soil 

 conditions, moisture and sun-light, so that it is difficult to separate 

 diiferent types. Should varieties still more distinctly different be 

 chosen for crossing, inore definite results would possibly be secured in 

 the resulting seedlings. The above data, however, show certain points 

 which are worthy of note. They indicate that there is a form of 

 combination of characters in some, at least, of the seedlings result- 

 ing from a cross between two varieties of cane. This ma\- be due 

 to certain characters derived from each parent variety, being domi- 

 nant in the heterozygous seedlings. It also appeai-s that there is 

 greater variation in seedlings so produced, than in those obtained 

 from tassels not cross-pollinated. 



As to the economic value of the seedlings produced by cros.sing,
