Abstract:

Survey was conducted at dough stage to assess the spot blotch disease of wheat in different locations of Jammu sub-tropics during 2015 cropping seasons. The disease was reported in all the wheat growing areas of Jammu subtropics with the maximum AIDX observed in Kathua district with the range of 29.55-48.15 per cent, followed by Samba ranging from 29.28-45.82 per cent. However, minimum disease was observed in Jammu district (30.06-40.61%). Out of sixty two wheat genotypes evaluated against spot blotch under natural epiphytotic conditions, 8 (HD-2967, HD-3043, HP-1102, HS-277, JAUW-598, PBW-660, PBW-692 and VL-907) were observed as resistant having disease severity of 34.26 to 35.0 per cent and AUDPC value of 330.90-402.80. While as, 24 genotypes were observed as moderately resistant having disease severity of 39.45 to 57.0 per cent and AUDPC value of 429.60-742.10. The rest of wheat genotypes belong to moderately susceptible and susceptible groups and having high disease severity and AUDPC value.
