Phenotypic diversity of five Jordanian populations of cyst nematodes, Heterodera spp.
collected from five regions from Jordan (Ar-Ramtha, Madaba, Dana, Al-Karak, and Jerash) was investigated.
Soil samples were collected from one representative field in each region.
Morphological and morphometrical characteristics revealed that Heterodera latipons is dominated in cereal fields at Ar-Ramtha, Madaba, Dana and Al-Karak regions and Heterodera schachtii in Jerash.
Cysts populations from all cereal fields had bifenestrate vulval cone and a strong underbridge.
Wherever, cysts of the cabbage population had ambifenestrate vulval cone with long vulval slit.
The bullae were absent in Ar-Ramtha, Madaba and Dana populations, but present in Al-Karak and Jerash.
Based on 12 morphometrical characters, the first three functions in canonical discriminant analysis accounted 99.3 % of the total variation.
Distance from dorsal gland duct opening to stylet base, underbridge length, a = L/W (body length/midbody width) and length of hyaline tail tip had strong and significant contributions in the first function.
While the second function was strongly influenced by length of hyaline tail, fenestral length, fenestral width and tail length.
However, the third canonical discriminate function was found to be influenced by stylet length, fenestral length, a = L / W (body length/midbody width) and underbridge width.
The graphical representation of the distribution of the samples showed that the first canonical discriminant function clearly separated H.
schachtii from Jerash from other populations.
Whereas, H.
