GENE ACTION FOR KARNAL BUNT RESISTANCE IN WHEAT

Published on

Kamal bunt of wheat (Triticum aestivum L.) caused by Neovossia indica (Mitra) Mundkur
is now a serious disease in India, Pakistan and Mexico.
It results in appreciable yield losses
and deterioration ofgrain and flour quality. The development ofboot inoculation technique
[1] has made it possible to screen wheat genotypes resistant to Kamal bunt under artificial
inoculation. The genetics of Kamal bunt resistance, however, is not well understood. Gill et
al. [2] using nulli-tetrasomics and ditelosomics of
T. aestivum cv. Chinese Spring reported
that there are many minor and major genes causing resistance/susceptibility to Kamal bunt
distributed among all the homoeologous groups. The present study is another attempt to
determine the nature of gene action for Kamal bunt resistance in a set of diallel crosses of
wheat involving resistant, moderately resistant, and susceptible cultivars. This will help in
planning breeding procedures for breeding Kamal bunt resistant varieties of wheat.
