Hierarchical cluster analysis based on cyst and cone top morphometric means including cyst length, cyst width, cyst length to cyst width ratio, vulval slit length, vulval bridge length, vulval bridge breadth, under bridge breadth, length of fenestra, breadth of fenestra, distance from anus to fenestra and number of secondary bullae was used to learn more about cyst and cone top morphometric means and their relationships for six populations of Heterodera zeae from Indore, Ludhiana, Delhi, Udaipur, Kanpur and Samastipur by using SPSS 13 for Windows computer software (SPSS Inc.). Values of proximity matrix based on cluster analysis of morphometrics and the dendrograms visually illustrated the grouping and relationships among populations. Intra specific variations in the different characters of the cone top structure revealed that Indore and Samastipur populations of H. zeae were different as compared to other ones of H. zeae. Cluster analysis of cyst morphometrics showed that the populations of H. zeae from Kanpur and Delhi were different as compare to other four ones.

W celu lepszego poznania morfometrii cysty i szczytu stożka wulwalnego sześciu populacji Heterodera zeae z rejonów Indore, Ludhiana, Delhi, Udaipur, Kanpur i Samastipur (India) zastosowano hierarchiczną analizę grupową używając oprogramowania SPSS 13 dla Windows (SPSS Inc.). Analiza obejmowała długość i szerokość cysty oraz stosunek tych wartości, długość szczeliny wulwy, długość i szerokość mostu wulwy, szerokość mostu dolnego, długość i szerokość okienka, odległość odbytu od okienka oraz liczbę wtórnych bulli. Wartości macierzy oparte na analizie grupowej morfometrii i dendrogramach ilustrują grupowanie się i związki pomiędzy populacjami. Wewnątrzgatunkowe zmienności w strukturach szczytu stożka wulwalnego różnych populacji wykazują, że populacje H. zeae z Indore i Samastipur różnią się od pozostałych, a analiza grupowa morfometrii cyst wskazuje na różnice pomiędzy populacjami H. zeae z Kanpur i Delhi, a czterema pozostałymi.
