Variability among Populations of Meloidogyne arenaria.
Variability in reproduction and pathogenicity of 12 populations of Meloidogyne arenaria race 1 was evaluated on Florunner peanut, Centennial soybean, Rutgers tomato, G70, K326, and Mc944 tobacco, and Carolina Cayenne, Mississippi Nemaheart, and Santanka pepper. Differences among M. arenaria populations in rates of egg production 45 days after inoculation were observed for all cultivars except S...
متن کاملIdentification of field populations of Meloidogyne spp. by chromosome number.
Identification of species of Meloidogyne Goeldi, 1887 is fi-equently accomplished by using perineal patterns and morphometrics, but intraspecific populations are not easily distinguished. Chromosome numbers have been determined for 10 (6) of the 36 species of Meloidogyne which are currently recognized (1, 5). Four of these species have a range of chromosome numbers. This chromosome range permit...
متن کاملInteraction of Meloidogyne javanica with Different Races of Meloidogyne incognita.
The interspecific interactions of Meloidogyne javanica with races 1, 2, 3, and 4 of M. incognita on tomato were determined. Impacts of the interactions on fecundity and morphometrics of females were also examined. Mutually inhibitory interactions occurred between M. javanica and the races of M. incognita, but the negative interactions did not reflect in plant growth. Numbers of root galls, egg ...
متن کاملMorphometric Evaluation of Hypotriploid and Triploid Populations of Meloidogyne arenaria.
A morphometric comparison of seven hypotriploid populations with five pooled triploid populations of Meloidogyne arenaria was made using standard descriptive statistics, stepwise discriminant analysis (SDA), and cluster analysis. Six morphometric characters of females, 14 of second-stage juveniles (J2), and 18 of males were measured for each population. Useful differentiating characters include...
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.
