Outline of Final Research Achievements

The high-yielding indica cultivar Takanari has one of the highest values of leaf photosynthetic rate (Pn) in rice. Five quantitative trait loci (QTLs) at which ‘Koshihikari’ alleles enhance Pn of rice in the Takanari genetic background were estimated on the short and long arms of chromosome 1, on the long arm of chromosome 3 and on the short and long arms of chromosome 7 and a line (HP-a) with 20 to 30% higher Pn value than that of Takanari was identified among backcrossed inbred lines derived from a cross between Takanari and Koshihikari. Four QTLs, which HP-a carries, were pyramided into a rice line via crosses among near isogenic lines carrying one QTL and it was demonstrated that the pyramided line showed high Pn value equivalent to that of HP-a. We then developed 20 rice lines carrying 2 to 5 QTLs in the genetic background of Takanari and compared Pn among lines. From a model analysis it was shown that each QTL increased Pn additively.
