Presenting: Two New Southernpea Varieties
By Luis Pons
March 23, 2005 Growers of southernpea in the
southeastern United States have two new varieties to choose from, including one
that resists a troublesome nematode.
The new cultivars are Charleston Blackeye, which resists root-knot nematodes
(Meloidogyne spp.), and Baby Cream, which offers high yields of small,
delicate peas. They were developed at the
U.S.
Vegetable Laboratory, operated in Charleston, S.C., by the Agricultural
Research Service (ARS), the
U.S. Department of Agriculture's chief
scientific research agency.
Southernpea, Vigna unguiculata (L.) Walp., is also known as cowpea,
crowder pea or black-eyed pea. It is coveted for its high protein, drought
tolerance and adaptability to poor soils. As a vegetable, it's widely used by
the frozen food and canned vegetable industries. It's also used as a cover crop
and as forage.
Charleston Blackeye, developed by geneticist
Richard
Fery and plant pathologist
Judy
Thies, is aimed at home and market gardeners who grow the traditional,
fresh-shell, black-eye type of peas.
Its parental lines are Bettergro Blackeye, a nematode-resistant cultivar
released 13 years ago by Fery and colleagues, and Au 84-G-328, a pinkeye-type
line developed at Auburn University. In
tests, Charleston Blackeye matured earlier, produced smaller seeds and
exhibited similar yield potential to Green Dixie Blackeye, a high-yielding
southernpea that ARS released in 2000.
Meanwhile, Baby Cream, developed by Fery over a 16-year period, has
early-maturing characteristics that give it potential to replace White Acre, a
leading commercial cream-type cultivar. These cultivars are popular because
their peas are succulent and have a milder, less starchy flavor and a better
appearance than black-eye types.
According to Fery, Baby Cream--a cross between White Acre and breeding line
US-432--should be more suitable than White Acre for use in modern, high-density
cropping systems. In tests, it produced dry pods one to two weeks earlier than
White Acre.
A limited quantity of seed of these new varieties is available to
southernpea seed producers who make a written request to Fery at 2700 Savannah
Hwy., Charleston, SC 29414, by March 31.
