100 STUDIES IN GUJARAT COTTONS 
we have again and again, as a result of it, been recommended to carry on 
selection on the basis of the tallness of the plants used forthe purpose. We 
have separated two strains: one (B3) which was the tallest of all in the 
sense that the main stem tended to develop to a great extent, and the other 
(E5) which did not have this faculty. The yield in kapas of each of these 
strains per acre grown side by side, in a series of years, was as follows :— 
Vicar B3 _ES 
( Tall strain ) ( Strain not tall ) 
Ib. Ib. 
1917-18 157 164 
1918-19 253 318 
1919-20 332 510

It is obvious that in these two strains, both isolated from Gogharz, there 
is no correlation between tallness and yield. It is difficult to understand 
how anyone ever supposed that such correlation was likely to exist. 
6. Description of certain pure line strains of Goghari cotton. 
From the discussion of Goghari cotton so far made, it has become clear 
that what goes under that name really consists of a series of strains, all of 
which possess the varietal features described on page 83, but which differ from 
one another by characters which are very important commercially, and of 
which some, at least, are hereditary and breed true. These strains, however, 
are not merely mixed ; they have crossed with one another to an enormous 
extent, and few, if any, of a pure character now exist inthe whole province. 
Any attempt to improve or even to fix astandard type for Goghart cotton 
must be commenced, evidently, by the development of such pure strains 
breeding true, which could be the basis of establishing types or of making 
crosses with other strains of Goghart or with other varieties of cotton. 
We have isolated five strains of Goghart cotton, and we may now give a 
description of each of these as it has behaved in pure line culture since 
1916-17 or 1917-18. 
Strain A26. 
The first of these selected strains, which has been termed A26, is derived 
from a selection originally made on the basis of the shape and the size of the 
boll. The manner of making the selection, in the first instance, was to pick out
