Interactions of Pratylenchus thornei and Fusarium oxysporum f. sp. ciceris on Chickpea.
ABSTRACT Fusarium oxysporum f. sp. ciceris and the root-lesion nematode Pratylenchus thornei coinfect chickpeas in southern Spain. The influence of root infection by P. thornei on the reaction of Fusarium wilt-susceptible (CPS 1 and PV 61) and wilt-resistant (UC 27) chickpea cultivars to F. oxysporum f. sp. ciceris race 5 was investigated under controlled and field conditions. Severity of Fusar...
متن کاملThe effect of temperature on hatching and penetration of chickpea roots by Pratylenchus thornei
Egg hatch of Pratylenchus thornei was influenced by temperature. It took place at all temperatures within the range 10–258C and was optimal at 208C. Root penetration increased steadily with increasing time of incubation up to the end of the experiment 11 days after inoculation. Temperature affected penetration rate in chickpea (Cicer arietinum) cultivars UC 27 and JG 62 but not in line P 2245, ...
متن کاملDifferential Pathogenicity of Four Pratylenchus neglectus Populations on Alfalfa.
A Pratylenchus neglectus population from lltah (UT3) was more virulent to Lahontan alfalfa than other P. neglectus populations from Utah (UT1, UT2) and Wyoming (WY). All alfalfa plants survived at 24 +/- 3 C when inoculated with WY, UT1, or UT2 at initial populations (Pi) of 500, 1,000, and 5,000 nematodes per plant. At Pi 10,000 with WY, UT1, or UT2, plant mortality was 15, 15, and 20%, respec...
متن کاملPathogenicity of Pratylenchus penetrans, Heterodera glycines, and Meloidogyne incognita on Soybean Genotypes.
The pathogenicity of Heterodera glycines, Meloidogyne incognita, and Pratylenchus penetrans on H. glycines-resistant 'Bryan,' tolerant-susceptible 'G88-20092,' and intolerant-susceptible 'Tracy M' soybean cultivars was tested using plants grown in 800 cm(3) of soil in 15-cm-diam. clay pots in three greenhouse experiments. Plants were inoculated with 0, 1,000, 3,000, or 9,000 H. glycines race 3 ...
