Plant Growth Response of Two Runner Peanut Cultivars to Reduced Seeding Hate !
The ability of peanut plants to adjust to wide plant-toplant spacing and the use of more precise mechanical planters have not been thoroughly exploited to reduce seeding rates. The magnitude of plant growth adjustment of two runner peanut cultivars to reduced seeding rate was studied in 1992 and 1993. A precision vacuum planter was used to plant the cultivars GK-7 and Southern Runner (SR) in si...
متن کاملEnhancement of Cylindrocladium crotalariae Root Rot by Meloidogyne arenaria (Race 2) on a Peanut Cultivar Resistant to Both Pathogens.
Two populations of Meloidogyne arenaria (race 2, incompatible on peanut) enhanced development of Cylindrocladium black rot (CBR) on CBR-resistant peanut cv. NC 3033 in greenhouse factorial experiments. Nematode populations 256 and 486 (0, 10(3), 10 eggs per 15-cm pot) were tested in all combinations with Cylindrocladium crotalariae (0, 0.5, 5, 50 microsclerotia per cm(3) of soil). Root-rot inde...
متن کاملIdentification of a new phytophthora species causing root and runner rot of cranberry in new jersey.
ABSTRACT In New Jersey, Phytophthora cinnamomi is the pathogen most commonly isolated from diseased roots and runners of the cultivated cranberry (Vaccinium macrocarpon). A second distinct species of Phytophthora has been isolated from dying cranberry plants and surface irrigation water. This species is homothallic with paragynous antheridia and ellipsoid-limoniform, nonpapillate sporangia. It ...
متن کاملCharacterization of Resistance Gene Analog Polymorphisms in sugarcane cultivars with varying levels of red rot resistance
Resistance Gene Analog (RGA) strategy is being exploited perfectly for the identification, tagging and mapping of major genes or Quantitative Trait Loci for disease resistance. About 29 RGA primers designed from the conserved domains of resistance proteins, were used to analyse the genetic diversity among the 40 sugarcane cultivars that vary in their resistance to red rot disease. The genetic s...
متن کاملManagement of Phytophthora Root and Runner Rot in Cranberry
Phytophthora is a genus of plant pathogens, many species of which live in water or soil. The name means “plant destroyer” in Greek. Phytophthora species are common pathogens in agricultural systems, especially in those where the crop is irrigated with surface or recycled water. In cranberry culture, the most troublesome species is P. cinnamomi, the cinnamon fungus. This pathogen causes a very c...
