STUDIES IN INDIAN TOBACCOS. 



Type 23 x Type 38, are given in Tables I, II, HI. In order to 

 shorten the tables the data are given in three-day periods. The 

 date of flowering of the parents under the same conditions was 

 determined each year. 



The most interesting results are those for the cross. Type 9 

 X Type 51. The parents vary greatly in time of flowering. 

 The"^ flowering period of the first generation is intermediate 

 between the two, but nearer that of Type 9, the earlier parent. 

 The Fo generation shows a wide range, but the flowering periods 

 of the parents is unfortunately not available for this year, 1911. 

 It may, however, be noted that the flowering period of the F2 

 covered two months, a period greater than that covered by both
