Selection of genotypes of peach rootstock resistant to Meloidogyne incognita
نویسندگان
چکیده
The aim of this study was to evaluate the genotypes developed by Peach Breeding Program at Federal University Viçosa, as regards resistance M. incognita. Six rootstocks propagated cuttings (713-07, 713-13, 913-3, 913-6, 913-11 and 913-17) two seeds (‘Okinawa’ hybrid between scion cultivars Aurora 2 x 1), were evaluated. experimental design randomized block with five replicates one plant per units. After establishing plants in pot, maintained a greenhouse, inoculated 11.000 juveniles + eggs Evaluations performed 140 days after inoculation. roots evaluated number galls egg mass determined. extracted from each for quantification determination Reproduction Factor (RF) nematode. peach 913-11, 913-17 713-7 showed an immune reaction Genotype 713-13 susceptible 1 confirmed susceptible.

Reproduction and Development of Meloidogyne incognita and M. javanica on Guardian Peach Rootstock.
Guardian peach rootstock was evaluated for susceptibility to Meloidogyne incognita race 3 (Georgia-peach isolate) and M. javanica in the greenhouse. Both commercial Guardian seed sources produced plants that were poor hosts of M. incognita and M. javanica. Reproduction as measured by number of egg masses and eggs per plant, eggs per egg mass, and eggs per gram of root were a better measure of h...
متن کاملEnergetics of Meloidogyne incognita on Resistant and Susceptible Alyceclover Genotypes.
To determine the energy cost of a population of Meloidogyne incognita on the roots of alyceclover, nematode biomass was estimated and equations in the literature were used to calculate energy budgets. Amounts of energy consumed, respired, or used in production of nematode biomass were calculated. Results suggested that severe infestations of root-knot nematodes can remove significant quantities...
متن کاملResistant Host Responses to Ten California Populations of Meloidogyne incognita.
Resistant and susceptible cultivars of tomato, lima beans, cotton, and alfalfa were tested with 10 populations of Meloidogyne incognita from different California locations. Nine of the populations differed in aggressiveness on the nine cultivars tested. Two populations were especially aggressive toward resistant tomato cultivars.

Rates of penetration and development ofMeloidogyne incognita race 4 in roots of resistant (inbred Mp307, and S4 lines derived from the open-pollinated varieties Tebeau and Old Raccoon) and susceptible (Pioneer 3110) corn genotypes were determined. Seedlings grown in styrofoam containers were inoculated with 5,000 eggs of M. incognita. Roots were harvested at 3-day intervals starting at 3 days a...

Meloidogyne incognita penetration and development were studied in roots of highly resistant (PI 96354, PI 417444), resistant (Forrest), and susceptible (Bossier) soybean genotypes. Although more second-stage juveniles (J2) had penetrated roots of PI 96354 and PI 417444 than roots of Forrest and Bossier by 2 days after inoculation, fewer J2 were present in roots of PI 96354 at 4 days after inocu...
