New High-Yielding Pecan Is Right for Many Regions
October 24, 2007
A new pecan called
"Lakota" is now available to nurserymen, thanks to scientists in the
Agricultural Research Service's (ARS)
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
Thompson and horticulturalist
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
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
Agricultures chief scientific research agency.
