Turmeric (Curcuma longa) is a high value export oriented important commercial crop among the spices. The production was declined due to several biotic and abiotic stresses. Among biotic stresses, root-knot nematode, Meloidogyne incognita is a major threat to turmeric cultivation. Seventy cultivars were screened to identify the resistance to root-knot nematode, Meloidogyne incognita. The result revealed that cultivars ‘Dugirala’, ‘PTS-31’, ‘Ansitapani’, ‘PTS-42’, ‘PTS-47’noted as fully resistant;‘361 Gorakhpur’, ‘328 Sugandham’, ‘PTS-21’ rated as moderately resistant and rest other cultivars were susceptible. The cultivar ‘328 Sugandham’ was moderately resistant to root-knot nematode. This was further confirmed through DNA amplification .. View More»
