Abstract:

New Japonica rice cultivar, ‘Tainung 86’, was hybridized by ‘Tainung 84’, a female parent with high grain yield and resistance to diseases and insects, and ‘Tainung 82’, a male parent with low grain protein in the 1_st crop season of 2014 in Chiayi branch station, Taiwan Agricultural Research Institute (TARI). From F₂–F₄ generations, modified bulk method was implemented to select separated lines, and pedigree method was applied to select new separated lines after F5 generations. New rice line, Chianung-yu 1061008, was selected to take part in regional trial and particular character test in the 1_st crop season of 2018. It was formally named ‘Tainung 86’ by a review committee in 2021. ‘Tainung86’ has stable grain yield, good grain appearance and eating quality, moderately resistance to leaf  blast and brown planthopper. It also improved the weaknesses from female parent-low grain yield andsusceptibility to bacterial leaf blight, and male parent-susceptibility to rice blast.

Key words:Rice, Japonica rice, Qryza sativa ‘Tainung 86’, Modified bulk method.
