Abstract
Morphological characterization of 12 advanced coloured rice genotypes was carried out using 39 morphological descriptors during Kharif, 2021 at Agricultural Research Station, Bapatla and the results revealed that 20 out of 39 characters showed variation. Estimates of Shannon weaver diversity indices for the characters studied ranged from 0 to 0.81. The highest diversity index of 0.81 was exhibited by the Flag leaf: attitude of the blade (late observation). Cluster analysis revealed that BPT2858 from cluster I was unique when compared to other cultures. DUS characterization of advanced rice genotypes helps the plant breeder to maintain the cultures with 100 % genetic purity and the cultures can also be used as parents in the breeding programmes based on the objective.
