Abstract:
Sugarcane is one of the important industrial multiproduct crop grown in India. The study of genetic diversity for twenty-two characters of sugarcane was carried out using Mahalanobis D² statistic. The genotypes of sugarcane obtained from different eco-geographical regions of India showed that there was a substantial genetic diversity between them with inter cluster distance (D) values ranging from 14.94 to 90.14. Forty-six genotypes were grouped into five clusters. The clustering pattern showed that the genetic diversity was not necessarily associated with its geographical diversity. These techniques help to quantify the variability available in used genetic materials and indicate groups of plants with similar or dissimilar genetic makeup.
