In order to explore the use of ‘GF98-296’ to solve the problem of seedlingless ridges in sugarcane roots, the effects on the agronomic traits of the directly replanted cane seed of ‘GF98-296’ in the ‘GL05-136’ ratoon were studied, which would provide a scientific basis for popularization and application. Three treatments including ‘GF98-296’ seed cane directly replanted in ‘GL05-136’ ratoon (A), ‘GL05-136’ seed cane directly replanted in ‘GL05-136’ ratoon (B) and ‘GL05-136’ natural ratoon (CK) were designed in this experiment. ‘GF98-296’ seed cane replanted was carried out in the 2-4 leaf stage of ‘GL05-136’ ratoon. The agronomic traits of the treatments were investigated and the economic benefits were analyzed in harvest stage. The yield of treatment A was 79.55 t/hm 2, which increased 19.29 t/hm2and 13.91 t/hm2, or 32.01% and 21.18%, respectively, compared with that of CK and treatment B, and the difference was extremely significant. There was no significant difference in yield between treatment B and CK. Direct replanting treatments did not affect the growth, yield and sucrose content of ‘GL05-136’ ratoon. The sucrose content of ‘GF98-296’ in treatment A was almost the same as that of ‘GL05-136’ ratoon at the technology maturity stage. Economic benefit analysis showed that sugarcane growers could increase income of 5071.0 yuan/hm 2 and sugar enterprises increase industrial output of 15 573.0 yuan/hm2 using ‘GF98-296’ seed cane directly replanting ‘GL05-136’ ratoon. The study indicated that ‘GF98-296’ was suitable for directly replanting ‘GL05-136’ ratoon, and this new technology should be extensively demonstrated and popularized.

Key words: GF98-296, GL05-136 ratoon, directly replanting cane seed, demonstration and popularization
