Hayman's diallel analysis for yield-related traits in F1 and F2 durum wheat (Triticum durum Desf.) progenies.

ABSTRACT: This study employed Hayman's diallel analysis to investigate the inheritance patterns of eight agronomic traits in durum wheat (Triticum durum Desf.) using a 4 × 4 half-diallel mating design evaluated across F1 and F2 generations. Field trials were conducted at the INRAA experimental station in Sétif, Algeria, during the 2021-2022 and 2023-2024 growing seasons. The analysis revealed significant genotypic variation across all studied traits, with distinct inheritance patterns emerging between generations. Plant height was predominantly governed by additive gene action. In contrast, spike length and number of grains per spike shifted from overdominance in F1 to partial dominance in F2, reflecting enhanced additive effects post-recombination. Yield components, including spike weight, number o
