| Summary: | The DUS test is an important tool for cataloguing the genotypes and utilization of variants in the crop improvement
programme. In the present investigation, a total of 55 early duration pigeonpea genotypes were categorized by
descriptors and cluster analysis for 21 agro morphological traits. Wide variations were observed in the characters viz.,
flower colour, a pattern of streaks, pod colour, seed colour, seed shape and size and no much variation was observed
for the remaining traits. The traits viz., earliness and prominent type of pod constriction were identified in all the
genotypes. The genotypes were partitioned into six clusters. Cluster I encompass 32 genotypes; cluster II consists of
seven genotypes; four genotypes each were placed in clusters III and V; clusters IV and VI comprised of five and three
genotypes, respectively. In the present study, the DUS descriptors and the variation observed in the early duration
pigeonpea genotypes will form the basis for designing the pigeonpea improvement programme.
