In vitro blast screening technique for genetic studies of rice

B. H. Chew

Abstract

A modified Yokoo and Hujimaki's multiple inoculation technique was described and its merits discussed. It had been brought to light the contrastic reaction of leaf and leaf which had been surface wounded in some genotypes in response to certain fungal races. Two types of resistance mechanisms were suggested, namely, the one that was conferred by the physical barriers of the leaf, and the one that was of intrinsic nature, either biochemically or physiologically. This improved technique was suitable for use in genetic studies of blast resistance in rice. It was time, space and labour saving too.
