Screening for resistance to false smut (Ustilaginoidea virens Takahashi) of rice (Oryza sativa L.).

摘要

An experiment was conducted during the kharif season in Patna, Bihar, India, to screen 98 rice genotypes for resistance to false smut (Ustilaginoidea virens) and to determine association of the disease with 26 morphological characters of rice. Out of 98 genotypes, 27 were highly resistant (<1%) and 45 were resistant (1-5%). Among the 26 morphological characters, only flag leaf length/breadth ratio exhibited highly significant and positive correlation with false smut disease..
