| Abstract: | Wandao 57,a medium indica rice cultivar,was developed from the cross (IR4412-164-3- 6/IR4712-208 -1) F1 radiated by r -ray. Its average yield was 7. 09t/ha in the two-year's (1988- 1989) province -levelregional trials, 12. 5% higher than that of check varirty Miyang 23,and 7. 14t/ha in the province level productivetest in 1990,5. 2% higher than that of Guicao 2 of check variety. It was characterized by gnd mophotype,robuststem,strong tillering ability, coodinating combination of spikelet and grain,and quality grain rice. The identifi-cation of diseases and pests by artificial inoculation showed that it possessed midddle resistance until resistance tobacterial lerf blight, resistance to rice blast,middle resistance until high resistance to white-back rice planthopperand resistance until high resistance to brown-back rice planthopper. Wandao 57 was the sort of early-maturingmedium indica rice cultivar. |
