The particular research aimed to evaluate the performance of 24 rice (Oryza sativa L.) genotypes comprising four local (Amber 33, Yasmine , Al-furat , and dajla) and four Egyptian cultivars (Giza 201, Giza 178, Giza 179, and Basmati 1). Completing the 24 were 16 hybrids obtained through the factorial hybridization method held in 2021 and 2022 at the Rice Research Station, Al-Mishkhab, Al-Najaf Al-Ashraf, Iraq. Significant differences were evident among the genotypes (varieties and their hybrids) in all studied traits. The hybrid Giza 201 × Al-furat excelled on traits of 1000-grain weight, biological yield, grain yield per plant, and harvest index (27.60 g, 429.33 g, 234.67 g, and 54.66%, respectively). The hybrid Basmati 1 × Dajla also excelled for biological yield, grain yield, and harvest index (405.33 g, 196.67 g, and 48.55%, respectively). Similarly, the cultivar Al-furat stood out for the above traits (367.67 g, 192.67 g, and 52.41%, respectively).
