Quality status of paddy (Oryza sativa L.) seeds at farmers level.

The quality of 15 rice seed samples collected from farmers in Gurdaspur, Punjab, India, was evaluated. Three samples (local cultivar and PR 8) were of low physical purity (93-95%) as the samples did not meet the minimum requirement of pure seed fraction (98%). Two samples had inert matter (including broken seeds, empty glumes, sand, stone, chaft, stones and leaves) more than the certification limit (2.0%). The moisture content of the 15 samples ranged from 8.5 to 10.7%, which was within the prescribed limit. The germination percentage was 78-99%. Two samples showed a germination percentage below the prescribed standard (80%), i.e. PR 8 (79%) and PR 111 (78%). Two samples (Padma and local cultivars) had Tilletia barclayana infection (0.55-0.60) that exceeded the prescribed limit

(0.50%).
