DELTAPINE 14 COTTON 



A FIELD OF DELTAPINE 14 COTTON 
The Crop History of the Deltapine 14 Strain 
Several of these strains were 
CROP OF 1942: That year the Delta and Pine Land‘Co. planted this 
new strain recognized by the Variety Standardization Committee as 
Deltapine 14. Seed of this strain was offered to the public in the 
autumn of 1942. 
CROP OF 1943: That season all of their principal properties were 
Poe with a new stock of Deltapine 14. The origin of this stock is 
as follows: 
_ In 1938 a large number of individual plant selections were made 
in the increase block of the strain later designated as Deltapine 14. 
In 1939 separate progeny rows were planted from each of these

selected for increasing in 1941 while being .further tested in thei1 
variety test and advanced strains test. One of these, No. 833, was 
finally selected for further increase and was planted in 1942 on a 
block of 80 to 100 acres. In 1943 this stock was planted on their 
Empire Unit and in 1944 is being planted on all of the other properties. 
On its record this strain appears somewhat superior to the original 
Deltapine 14 in yield, earliness, and in length of staple. It has not 
outyielded the selected Deltapine stock of 1943, referred to above, 
but has given definitely better spinning results. While Deltapine 
14-833 represents some improvement on the original stocks, it will be 
introduced commercially as Deltapine 14 in keeping with their policy 
of not changing strain numbers unless a distinct change in char- 
acteristics is obtained through their breeding program. 
plant selections. They were carefully studied in the field and a 
number of them were eliminated there. Later the. samples ginned 
from each progeny row were analyzed by fibrograph for length and 
uniformity in the Fiber Laboratory of the University of Tennessee. All 
of the progeny rows conforming to a standard of length and uni- 
formity were then bulked to form an increase stock. This increase 
stock-of Deltapine 14 was planted in one 8-acre block in 1940. Seed 
produced there were planted in 1941 as far as they would go. In 1942 
their Empire Plantation unit of 1,300 cotton acres was planted exclu- 
sively with this stock and in 1943 all of their other plantation units 
were planted with it and seed from this crop was sold to the public. 
In three years of testing this selected stock each year outyielded 
the original stock by more than 3%, which is statistically significant.
