A new pecan called "Lakota" is now available to nurserymen, thanks to 
scientists in the Agricultural Research Service's (ARS) Crop Germplasm 
Research Unit at College Station, Texas, and a collaborator at Kansas 
State University (KSU). Lakota is notable for its high yield potential, 
the early maturity and quality of its nuts, and excellent tree 
strength.

At the helm of this research effort were geneticist Tommy Thompson and 
horticulturalist L.J. Grauke, who conduct the ARS national pecan 
breeding program. Working with them was William Reid, a horticulturist 
at KSU at Chetopa.

Lakota kernels are cream to golden in color, and shell out easily into 
very attractive halves. There are 59 nuts per pound, of which 62 
percent (about 10 ounces) is kernels and 6 ounces is shell. Lakota has 
early- to mid-season female flower receptivity and mid- to late-season 
pollen shed.

The new pecan has performed well in tests in the northern pecan 
production areas of Kansas, Missouri, Illinois, Oklahoma and Texas. 
Trees are vigorous and upright in growth habit and develop strong limb 
angles and a wind-resistant structure.

Lakota is very resistant to scab disease, an infection that causes 
premature nut drop and can prevent nuts from fully expanding, thus 
decreasing nut size. It also has medium susceptibility to yellow and 
black aphids that suck photosynthesis-produced sugars and plant 
nutrients from the leaves and excrete sticky honeydew. This aphid 
feeding damage also reduces the flow of nutrients to nuts, 
significantly reducing yields.

Lakota is a potential commercial cultivar for all pecan production 
areas. Initial data indicate that it is early enough in nut maturity to 
be grown in the northern production area, and it has enough scab 
resistance to be grown throughout the southeastern United States.

Small quantities of grafted trees will be available from selected 
nurserymen, beginning this winter.

ARS is the U.S. Department of Agriculture’s chief scientific research 
agency.
