Abstract:
A field experiment was carried out with 109 diverse indigenous genotypes of bread wheat along with four checks in Augmented Block Design for genetic variability, character association and divergence analysis, divided in to 7 blocks of equal size. Each block had 15 plots of test entries along with 4 checks (viz. LOK-1, HD-2009, WH-147 and DBW-17). The trial was conducted at Main Experimental Station Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during Rabi 2015-16. The observations were recorded on eleven quantitative characters viz.,days to 50% flowering, days to maturity, plant height(cm), tillers per plant, spike length(cm), flag leaf area(cm), peduncle length(cm), 1000-grain weight(g), biological yield per plant(g), harvest index(%) and grain yield per plant(g). Results revealed that 105 indigenous lines and 4 check varieties of wheat were grouped into eleven distinct clusters by using non hierarchical Euclidean cluster analysis. It indicated the existence of high degree of genetic diversity present in the varieties/lines. Therefore, these varieties/lines may serve as valuable source for selection of diverse parents. Maximum intra-cluster distance was found for cluster-VI followed by cluster-XI, the minimum intra-cluster distance was recorded for cluster-VII followed by cluster-II. The highest inter-cluster distance was observed between cluster-IV and cluster-XI followed by cluster-III and cluster-XI. The lowest inter-cluster distance was observed between cluster-I and cluster-II followed by cluster-VII and cluster-IX. Hence, crosses should be made between these widely related genotypes located in intra and inter cluster distances, to get desirable extent of heterotic potential in order to increase the production and productivity of wheat in North Eastern Plain Zone of Uttar Pradesh.
