Abstract:
Selection of appropriate genotypes based on characters that show good genetic strength is a very important tool in crop improvement since selection could not be carried out based on all characters. Study of interrelationship and association of characters is essential to identify the variables which show maximum relationship with others. Correlation analysis was carried out presently in the case of 12 morphometric characters in vetiver (Vetiveria zizanioides) so as to study the relationship between them. The present study revealed varying degrees of interrelationship between the morphometric characters studied. Character association was also studied so as to group the characters based on gene sharing and to identify the lead characters that could be used in further breeding programmes. Plant height showed the highest factor loading followed by leaf breadth, root length, leaves per tiller and fresh root weight showing their higher contribution towards the variability of the population and their usability in breeding programmes as lead characters.
