Abstract:
The seventy four genotype along with their four check varieties (Sarjoo-52, Pusa-44, NDU-3 and Kala Namak) were tested against the Bacteria leaf blight, under sodic soil during Kharif, 2020 at the main experiment Station Acharya Narendra deva University Of Agriculture and technology Kumarganj, Ayodhya (U. P.). The experiment was conducted in sodic soil at pH =9.2, EC =2.21dSm-1 and ESP 45%. Resistance against Blast was assessed based on the damaged leaves following 0-9 scale as per the SES, IRRI, Manila, Philippines. Two genotype found immune. Ten genotype were resistant and recorded damage score of “1” indicating resistance to BLB. Twenty five genotype and two check Pusa-44 & Kala-Namak were moderately resistant and eight genotype were found to be moderately susceptible to BLB damage. The genotypes which were highly resistant may be used as donors in resistant breeding programmes against Xanthomonas oryzae pv. oryzae.
