Inheritance of Resistance to Bacterial Leaf Blight, Xanthomonas Oryzae (Uyeda et Ishiyama) Dowson, in Rice : I. Allelic Relationships of Resistance Genes in Donor Varieties

Abstract

Allelic relationships of genes for resistance to bacterial leaf blight were studied in several varieties. Sigadis and TKM 6 have same genes for resistance. BJ 1 on the other hand has different genes for resistance. Wase Aikoku 3 and PI 215936 have non-allelic genes. Sigadis and PI 215936 also have non-allelic genes. Zenith and B 589 A 4-18-1 have allelic genes. Allelic relationships of genes for resistance in Zenith and Sigadis are not clear.
