Not AvailableRhizoctonia solani [Teleomorph: Thanatephorus cucumeris (Frank) Donk.] is a major disease of rice. The disease is increasing over the year in India and cause up to 69% yield loss under favourable conditions. The disease is highly influenced through different disease variables and environmental factors. A correlation study was done to know effect of different disease variables on disease pattern during screening of the wild germplasm and F2 population. Based on screening during kharif 2015, 16 best accessions of Oryza nivara, 22 accessions from Oryza rufipogon were screened during kharif 2016 and 2017. Total of 480 plants in F2 populations were also included for correlation study. The study revealed that in whole screening experiments, different disease variables were significantly (P<0.05) correlated. Relative lesion height had a positive correlation with lesion height and disease score. The lesion height showed positive correlation with disease score. There was a negative correlation between plant height and disease score.Not Availabl
