Character association and path coefficient analysis in wheat (Triticum aestivum L. em. Thell)

Abstract

A field experiment was carried out with 109 diverse indigenous genotypes of bread wheat along with four checks in Augmented Block Design for study of character association and path coefficient, 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 the experimental field was divided in 7 blocks. Each have had 15 plots of the entries with 4 checks.
