Availability of genetic variation for productivity per se traits and responses to economically important production constraints in the working germplasm is a prerequisite for breeding crops and blackgram is no exception to this. The experiment was carried out with 116 blackgram germplasm accessions along with two checks were evaluated in RCBD design during summer season at 2014, in the experimental fields of Department of Biotechnology, GKVK, UAS, Bangalore. The genotypes were evaluated for root traits in PVC pipes during 2014 summer. The accessions differed significantly for all the root traits and could be grouped into five clusters based on K-means clustering. The root trait means and variances of accessions included in the five clusters differed significantly. The genotype LBG-685 manifested higher grain yield coupled with maximum root length.
