Abstract:
The present investigation was carried out during Rabi 2017-18 at Main Experiment Station Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Ayodhya (U.P.) with the objectives of estimating genotypic variability, heritability, genetic advance and associations among yield and yield-related characters of Triticum aestivum. The variation due to blocks was highly significant for flag leaf area, plant height, spike length, tillers per plant, peduncle length, biological yield per plant, grain yield per plant, 1000-grain weight and harvest index. The highest estimates of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was observed in case of peduncle length (PCV 14.04 %, GCV = 13.88%) followed by flag leaf area (cm2) (PCV=11.77%, GCV=11.50%). The high heritability was recorded in peduncle length (cm) (97.69%) followed by flag leaf area (cm2) (95.54%), biological yield per plant (g) (93.83%), spike length (cm) (92.10%), and plant height (cm) (91.88%). The highest value of genetic advance was shown by peduncle length (cm) (28.26%), and flag leaf area (cm2) (23.17%). The high estimates of heritability coupled with high genetic advance were found in peduncle length (cm) and flag leaf area (cm2) both traits were regulated by additive gene effect. That region the selection of genotypes based on these two characteristics are more useful and effective for genetic improvement of genotype.
