Abstract

Studies were made to enhance the seed quality of lucerne cv. CO 1 through physical seed management. Seeds were size graded using 12, 14, 16, 18, 20 and 22, sieve number of British Standard Sieves (BSS). The seeds were also separated into three colour grades viz., yellow, light brown and dark brown, based on the availability of colours in the seed lot. Graded seeds were evaluated for seed germinability and vigour parameters. The study recorded a positive association of seed quality within the size grades. Based on higher recovery combined with higher quality, the seeds shoukl be graded with BSS 14 x 14 size sieve. Among the colour grades, yellow coloured seeds are to be selected for better seed quality performance than other colours.
