Genetic analysis of blast (Pyricularia grisea Sacc.) resistance in rice (Oryza sativa L.)



Genetic analysis of blast (Pyricularia grisea Sacc.) resistance in rice (Oryza sativa L.)



Journal of Biological Sciences 7(1): 215-217



The genetic analysis of blast (P. grisea resistance in rice (O. sativa) was conducted in Chhattisgarh, India. The inheritance studies revealed that, resistant parents RR 166-645 and Bala possessed a single dominant gene, which is effective against one or more races of blast. The resistant line RR 345-2 and moderately resistant lines IAC 25 and IR 42221-2-3-2 possesses two independent dominant genes, each gene providing resistance against a single but different race.
