Resistance in Kalauamak against Panicle Blast Caused by Maguaporthe grisea

Abstract

Kalanamak is one of the most important small and medium grained indigenous aromatic rices of India. Panicle blast, caused by Magnaporthe grisea, is one of the most serious problems of Kalanamak. Susceptibility of 37 germplasm of Kalanamak was tested against panicle blast under field conditions during the years 1999 and 2000. These germplasm showed wide variation in their susceptibility towards panicle blast. Ten germplasm were resistant to panicle blast. Some germplasm exhibiting moderate to high resistance towards panicle blast were also supedor in yield and other quality traits.
