Karnal bunt resistance in wheat embryos on different time regimes of grain development in bixenic cultures

Abstract

Karnal bunt (KB) [(Neovossia indica (Mitra) Mundkur)], an important disease of wheat causes partial conversion of individual kernels into sori, filled with teliospores and sterile cells resulting in losses in both yield and quality [1]. The infected grains emit an unpleasant fishy odour due to trimethylamine. The disease has a great significance in global wheat trade because of stringent quarantine measures. The development of KB resistant varieties is difficult as the disease expression is highly influenced by the environment. So finding some easy way to screen against the disease will help to develop resistant genotypes using conventional as well as molecular techniques.
