Based on breeding results, a new F1 watermelon hybrid ‘Kirodar F1’ was created. The hybrid was created on a fertile basis using new parental lines identified by genes that control expression of marker (signal) morphological traits: ‘Busynka-25’ and ‘Bor-25’. Monoecious line ‘Busynka-25’ became the female line of the hybrid; its novelty lies in combination of high monoeciousness, early ripening, resistance to anthracnose and Fusarium wilt, and high yield. Line ‘Bor-25’, which combines early ripening, tolerance to abiotic stressors (cold, heat) and biotic factors (anthracnose and Fusarium wilt) factors with valuable economic traits served as the male line of the hybrid. In 2025, the lines were submitted to the National Center for Plant Genetic Resources of Ukraine as accessions the Ukrainian plant gene pool. Via hybridizing these new lines, a new early-ripening, high-yielding watermelon hybrid ‘Kirodar F1’ was created. The new hybrid yields by 32-45% more fruits with quality indicators improved by 2-3% compared to analogs. The hybrid is highly resistant to diseases, suitable for transportation and short-term storage. The economic effect from growing the new hybrid ‘Kirodar F1’ is 104,500 UAH/ha. The hybrid was submitted for qualifying examination to the State Variety Trial Service in 2025. Hybrid ‘Kirodar F1’ is recommended for growing in the Forest-Steppe and Steppe of Ukraine
