At the Crop Genetics Research Unit in Stoneville, Mississippi, ARS plant pathologist Sally Stetina and plant geneticist John Erpelding are conducting a program to insert genes for reniform
nematode resistance into cultivated upland cotton varieties.
cornifera were curved or reniform
, and similar to those of C.
Spermathecae: two spermathecae of similar size originate from the copulatory chamber, each with a short duct and a globulose or reniform
Psilomelane, corresponding to Haidinger's "uncleavable manganese ore," was the name given to some dull black, sometimes reniform
, massive specimens and, presumably, to whichever massive, dull black manganese ores were not instead designated "wad.
nematode (RN) is found in the southern parts of United States and known to attack at least 300 plant species.
Grass family crops, such as small grains, corn, sorghum, millet, and forage grasses are good crops to rotate with cotton because they support few root-knot and reniform
In the other species the ascomata are small and thin walled and the ascospores are oblate, fusiform or reniform
leaves are a characteristic feature of this species that is reflected in its botanical name "reniforme" (Van der Walt and Vorster, 1983, 1988).
Seedling survival two and four weeks after planting; thrip counts at three and six weeks after planting; reniform
nematode populations at planting, midseason, and at harvest; and yield were collected for each trial.
GP-797, PI 636104) were released because they are resistant to the southern root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood Race 3], have field tolerance to the reniform
nematode (Rotylenchulus reniformis Linford & Oliveira), and good productivity and fiber quality.
The kidneys were symmetric, reniform
, markedly elalarged and cystic, with a combined weight of 120 gm, when the expected weight is 34 [+ or -] 9 gm.
Ascospores: Uniseriate, reniform
with one side flattened, blackish-brown, 1-2 guttulate, 10-12 X 5-6 [mu]m.
