Characterization of Agromorphological Diversity in Synthetic Bread Wheat (Triticum aestivum L.) Genotypes Targeted for Higher Yield Potential

Background and Objective: Triticum aestivum (hexaploid genome i.e., AABBDD) belongs to family Poaceae-having five subspecies. The important species of are Triticum monococcum (einkorn), Triticum dicoccon (emmer) and Triticum spelta (spelt). The main objective of the study was to identify and evaluate different genotypes of wheat for potential yield. Materials and Methods: The current study evaluated 39 wheat genotypes of diverse origins with 20 agromorphological parameters based on ANOVA and LSD analysis, descriptive analysis and correlation test. The germplasm was planted in Randomized Complete Block Design (RCBD) with three replications and spacing between the rows was kept at 75 cm and the width was 12 cm. Results: Maximum grains per spike were observed in accession number 11 and recorded at 91.00 grains per spike while minimum grains per spike was observed in accession number 22 and recorded as 20.00 grains per spike. The greatest value of thousand-grain weight was observed in accession numbers 17 and 24 which were recorded as 50 g while the smallest value was observed in accession number 38 which was recorded as 30.24 g. The greatest harvest index was observed in accession number 11 which was 69.0084 while lowest value was observed in accession number 7 which was 30.4491. Conclusion: Combining the results of all parameters accession no 11, 17 and 24, are superior lines and may be used for increasing the yield potential of future synthetic wheat lines. Current study results may facilitate future wheat improvement programs as well as the development of agronomically desirable wheat cultivars.
