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
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
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.
