主 题：Hybrid japonica rice Rice blast Resistance gene
摘 要：The distribution of rice blast-resistant genes Pi2, Pi5, Pi9, Pi54, Pia, Pib, Pit and Pita in 36 restoring lines and 42 sterile lines were detected using functional molecular markers. The results indicated that those eight blast-resistant genes distributed in the 78 tested lines at various frequencies. Six rice blast-resistant genes were detected in the sterile line Shen 11 A, containing the most rice blast-resistant genes among the 78 lines, whereas no rice blast-resistant gene was detected in the lines 8527 A, Xu1 A and 016 A. The genetic distance-based clustering analysis showed that those 78 lines could be divided into five groups.
