3. Strain No. B3 Goghari. The boll characters were again studied 
and after being constant in 1916-17 and 1917-18 these showed | per cent. of 
the plants in 1919-20 with varying bolls, 
Judged therefore by this one character, it would suggest that under the 
conditions of the experiment. in which the nearest differing plants of other 
strains would be six feet or more away, the amount of crossing would, in 
Goghart cottons be between 1:0 and 2°8 per cent. 
That the plants at present grown are unfixed hybrids of the varieties in 
cultivation is still more clear. Seed of twotypes of Goghari cotton ( Jambusar 
Goghart and Varnama Goghar. ) were obtained and sown. From the crop 
obtained, all plants were eliminated which showed any character other than 
those associated with Goghart cotton. Seed was produced from the remainder 
and this was again sown. Instead of producing pure Gohgart plants, 
however, the latter showed a higher percentage of admixture with those of 
other types than did the original cotton. The actual figures in both cases 
are as under :—

Broach deshi Broach deshi 
First year (1913-14 ) 7°25 9°5) 
Second year (1914-15) 14:00 10°00 
It is clear, therefore, that the plants grown were “splitting ’’ as to one or 
more of the characters associated with Goghari cotton. 
A similar test was made with a sample of cotton seed, reputed to be Broach 
deshi, obtained at Broach. The seed was grown as before, and all the plants 
which did not conform to the Broach deshi type were eliminated, and the seed 
produced from the remainder was sown in the following generation. In this 
case the series was continued for four years ; only in the fourth year had the 
Groghari type been entirely got rid of, asthe following figures show :—
