Abstract
A field experiment was conducted at Instructional Farm, Uttar Banga Krishi Viswavidyalaya, during the 2018-19 rabi season to study the genetic components and genetic variability based on eleven number of quantitative traits in 254 bread wheat lines, which were collected from NBPGR, New Delhi. Analysis of variance for treatment showed high significance for all the traits except grain yield polt-1. Estimated GCV and PCV were high for awn length, peduncle length, plant height and AUDPC. Plant height (97.83), awn length (95.49), peduncle length (94.88), test weight (90.98), days to 50% flowering (87.66), number of grains spike-1 (70.33) and spike length (62.3) showed high heritability along with a high degree of genetic advance. Finally, 254 wheat accessions were grouped into three clusters based on the dendrogram analysis using the ward method.
