GENETIC DIVERGENCE ANALYSIS IN TUBEROSE (POLIANTHES TUBEROSA L.) GENOTYPES

Farm, Department of Horticulture, Assam Agricultural University, Jorhat during 2016-17 and 2017-18, to study the genetic diversity in tuberose (Polianthes tuberosa L.) genotypes.The experiment was laid out with eighteen tuberose genotypes in Randomized Block Design (RBD) with three replications.Observations were recorded for growth, flower and physiological characters.Based on D 2 values, the genotypes were grouped into seven clusters.Maximum inter cluster distance was observed between cluster 6 (Phule Rajani) and cluster 3 (Subhasini and Vaibhav).Traits viz.duration of spike, number of spike per bulb planted and yield per spike had highest contribution towards genetic divergence.
