Grain discolouration

1. Discoluration of rice grains. is becoming a major problem in certain varieties of rice both in upland and lowland conditions. It redUces the germination, causes decay of seedlings, produces chaffy grains and lowers the consumption quality of the grains.
2. The disorder may be limited to individual grains, but in severe cases almost the entire panicle including the rachis becomes discoloured.

Bunt

1. In Bunt disease, a few grains in an ear are affected, the infection being either partly or wholly. The symptoms appear first as minute black Streaks bursting through the glumes at the ripening.
2. If the infected grain is crushed between the fmgers, a black powdery mass of spores emerges. The causal organism of the disease is Tilletia barclayana.
3. The is that develops inside the grain is filled with spores, which are spherical and dark, with a spiny epispore. The spore germinates and produces sporadic. These produce secondary sporadics in large numbers.
