Fig. 3 Frequency distributions of plant height, primary branches per panicle and grain width in the secondary segregated populations and Manhattan plot of ?(SNP-index) A: frequency distribution of plant height in secondary segregated population related of qPH7; B: ?(SNP-index) graph of plant height extreme mixed pools; C: frequency distribution of primary branches per panicle in secondary segregated population related of qPBPP8-2; D: ?(SNP-index) graph of primary branches per panicle extreme mixed pools; E: frequency distribution of grain width in secondary segregated population related of qGW10; F: ?(SNP-index) graph of grain width extreme mixed pools. The blue and red triangles represent the positions of the means of Nipponbare and its related CSSL, respectively.
