Abstract

Twenty nine accessions of gobhi sarson were evaluated for eight agro-morphological traits and classified using metroglyph analysis. These accessions exhibited substantial variation for all the agromorphological traits except for the days to maturity (CV 8.1%) and oil content (CV3.6%), the maximum being for secondary branches/plant (CV 59.8%). The cluster I was the largest with 34.5% of the accessions. Eight acessions did not fall in any group. The cumulative index score ranged from 10 (NECN 15 to 19 (NECN 8). About 24.1% of the accessions have the mean index score of 13. Group IV had the highest mean index score of 14.7. Eight accessions having high index score were identified for the possible use as donors in the hybridization programme and their characters were presented.
