Abstract

Detection of seed born pathogen is important as it disseminates to the next crop using seed as medium. Identification of the hidden pathogen with seed will offer the way to take precautionary measures for seed treatment. Study was carried out to evaluate the seed health, such as germination, pre-emergence death, post-emergence test, infection (%) and presence of different seed-born pathogen of 11 inbred lines developed from a cross between Kalonunia and Pusa Basmati 1637 along with these two parents. Four different genera of pathogens were identified, Aspergillus, Penicillium, Curvularia and Magnaporthe. Aspergillus was predominant and it was found in all the seed lots. As the duration of seed in storage increased the germination reduced. No notable increase or decrease in infection was noted with the duration of seed storage.
