‘Roko 20’ is high-yielding, medium-maturity japonica rice variety adaptable to Romania and Turkey. It was developed and registered (Registration Nr. 6578 in ISTIS, Romania) from a cross between ‘Haedamssal’ and the salt resistant Romanian cultivar ‘Polizesti 28’ in 2021. The vegetation period of ‘Roko 20’ was 121 days in Turkey and 136 days in Romania. The culm length of ‘Roko 20’ was 80 cm, and the 1,000-grain weight of paddy rice was 31.0 g. The ripening ratio was similar to that of the control cultivar ‘Polizesti 28’ at 81%, and the proportion of amylose content of brown rice was 18.5%, which was slightly lower than that of the control cultivar ‘Polizesti 28’ (20.2%). The paddy rice yield was 18% higher than that of the control cultivar with 8,535 kg/ha. The proportion of brown rice and milled rice recovery was 81.6% and 65%, respectively. However, the head rice was slightly lower (44% in Turkey and 49% in Romania) than that in ‘Polizesti 28’ (52%).
