132 TILLERING IN INDIAN SUGARCANES 



From a study of this table we get the following order of development as 

 judged by the various comparisons in the columns 1-5. Sunnabile (Dhaulu), 

 Saretha (Brown), Nargori, Unclassified indigenous, Sunnabile, Mungo (Kharwi), 

 Pansahi, Saretha, Thick cane3, Siicclmram spontamam, Mungo, 8aretha (Green), 

 Sunnabile (Dhor), Mungo (rest). But we have, in addition, to consider the 

 ages of the plants dissected. It is thus seen that the position of Sunnabile 

 (Dhaulu) at the head of the table must be qualified, firstly, by the fact that 

 in these members of the section, only a single plant developed in each clump, 

 presumably assisting in rapid maturing, and, secondly, that the dissections 

 were made late (4 weeks after the Brown section of Saretha), because of the 

 slow development of Dhor and Sunnabile. Saretha (Brown) is obviously the 

 quickest of all in maturing. Similarly, the juxtaposition of the Saretha and 

 Thick cane groups, examined at 109 and 150 days respectively, indicates 

 that the latter are much later in development than the former. So the Mungo 

 group, excepting Kharivi, are very late indeed, being near the bottom of the 

 list, although dissected moderately late (129 days). But the method is interest- 

 ing, although unsatisfactory for generalizations. 



The only way in which these various defects can be avoided is to take the 

 groups and sections separately and compare them with the rest in the following 

 manner. Saretha (Brown) is ahead of Pansahi, although examined a week 

 earlier. There are more canes formed, and, in these, there is a slightly larger 

 proportion of canes over than under 3' in length ; there are practically the 

 same number of immature shoots, but in these too there is a slight excess of the 

 shoots over 3' long in Saretha ; there are only half the number of buds and 

 there are slightly more deaths. If the tillering power of the two groups is 

 considered, there is a larger proportion of canes formed in Saretha in 110 

 days than in Pansahi in 116. It may therefore be safel}^ concluded that the 

 Brown section of the Saretha group is earlier in its development on the farm 

 than the Pansahi group. The same method may be applied all through and, 

 as a result, we can place the groups roughly in the following order : — 



Early maturing, Saretha (Brown), Nargori, Pansahi, Saretha, Sunnabile 

 (Dhaulu), Mmigo (Kharwi) ; 



Moderately early maturing, Various indigenous, Saretha (Green), 

 Saccharum spontaneum, Thick canes ; 



Late maturing, Sunnabile, Mungo, Mungo (rest) and Sunnabile (Dhor). 



The full table of analyses of the different varieties is annexed, the figures 

 in each group being the averages obtained for each clump.
