tailieunhanh - Screening of different cultivar of paddy and wheat against root-knot nematode Meloidogyne graminicola
Screening of some rice and wheat cultivars were tested for their resistance against rice root-knot nematode (Meloidogyne graminicola). The investigation was conducted on 19 Paddy cultivars along with 12 wheat cultivars, which showed evidence of damaging potential of Meloidogyne graminicola in terms of plant growth parameters and disease incidence. Disease intensity grade was classified on the basis of root knot index. Out of ninteen cultivar, 6 were moderately resistant to Meloidogyne graminicola while 2 varieties Pusa basmati and JR 503 susceptible with maximum number of galls per plant ( and 57) while the 6 cultivars, IR64, JR75, Poornima, Shyamla, PS3 and Madhuri showed resistant reactions. Another rest cultivars, Mahamaya, Luchai, IR36 Kranti, JR201 and Shriram showed highly resistant to root-knot nematode M. graminicola. All cultivar of wheat showed susceptible reaction to root-knot nematode. | Screening of different cultivar of paddy and wheat against root-knot nematode Meloidogyne graminicola
