Abstract:
The present investigation entitled “Genetic divergence analysis and character association in different genotypes of wheat (Triticum aestivum L.)” conducted on 94 accessions of wheat during 2019-20 at Main Experiment Station (MES) of A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) to evaluate genetic divergence and character association for the identification of most diverse and promising genotypes. The experiment was laid out in Augmented Block Design. The observations were recorded on various morphological and physiological characters viz., days to 50% flowering, days to maturity, plant height, number of productive tillers per plant, peduncle length, spike length, nhumber of grains per spike, test weight/1000-grain weight, grain yield per plant, biological yield per plant and harvest index. Results revealed that 90 indigenous lines and 4 check varieties of wheat were grouped into ten distinct clusters by using nonhierarchical Euclidean cluster analysis. Field experiment based non-hierarchical Euclidean clustering for eleven physiological traits for 94 genotypes shows the maximum inter – cluster distance between cluster IV and VII followed by cluster IV and VI and cluster II and VII. The maximum intra – cluster distance was observed in cluster X followed by cluster IX and cluster V.
