Resistance in Rice (Oryza sativa L.)]]>PersaudMahendra KumarA. SengarR.B.S. SaoAbhinav DantreR.K. ShrivastavaM.N. 1200771The genetic analysis of blast (Pyricularia grisea Sacc.) resistance in rice (Oryza sativa L.) 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. Allelic tests showed that, the genes conferring resistance to blast present in RR 166-645 and RR 345-2 are non-allelic. Similarly, the resistance conferring genes in WAB 56-50 and B 61444-F-MR-6-0-0 are also non-allelic.]]>Atkins, J.G. and T.H. Johnston,1965Pyricularia oryzae.]]>55993995Babugee, M. and S.S.
