Evaluation of some commercially grown polyhouse cultivars for their susceptibility/ resistance against Meloidogyne incognita

Abstract

The present piece of scientific investigation entitled “Evaluation of some commercially grown polyhouse cultivars for their susceptibility/ resistance against Meloidogyne incognita” was conducted in Dr YSP UHF, Nauni, Himachal Pradesh polyhouse to explore the possibilities of nematode management in highly susceptible cucumber crop by using environment friendly management tools. Observations regarding seedling status in terms of length at transplanting, fruit yield, nematode population and gall index in case of root knot nematode at termination were recorded. When selected cultivars viz. Cucumis sativus var. Maharaja, Cucumis sativus var. PCUC-15, Cucumis sativus var. Pusa Sanyog, Cucumis sativus var. Kheera Hybrid-1 and Cucumis sativus var. Kian screened against M. incognita were found to be highly susceptible; Kian and Kheera Hybrid 1 being more susceptible to M incognita as compared to other three test cultivars. However, variations in the yields of various cultivars seemed to be more due to their inherent yield characteristics and less due to variations in their susceptibility level.
