Abstract

An investigation consisting of 36 fenugreek genotypes and one check (Pusa Early Bunching) was laid out in Randomized Block Design with three replications at Pantnagar Centre for Plant Genetic Resources (PCPGR) of the G.B.P.U.A & T, Pantnagar, Uttarakhand during rabi season of 2016-17 and 2017-18 and observations were recorded on sixteen different traits. The traits viz., number of pods per plant, thousand seed weight and leaf yield per plant exhibited high direct effects on seed yield per plant along with significant positive correlation indicating that these traits can be used as most important selection criteria for seed yield improvement. The diversity analysis leads to formation of nine different clusters and maximum intra-cluster distance was observed in cluster IV (21.07) while highest inter-cluster distance was recorded between cluster VII and IV (46.07). These clusters actually represent the different heterotic pools and genotypes from diverse pools can be crossed to obtain heterosis and transgressive segregants.
