Teyou 37 Teyou 37 is a new hybrid late indica rice combination bred by the Institute of Nuclear Agricultural Sciences of Zhejiang University. In the 2000 provincial production trial, the average yield per mu was 448.8 kg, an increase of 1.91% over Shanyou 10. Results from two years of regional trials: the average whole growth period was 129.8 days, the average effective panicles per mu was 175,000, the seed-setting rate was 83.7%, and the 1000-grain weight was 26.9 g. Its resistance identification results: moderately resistant to rice blast, susceptible to bacterial leaf blight, susceptible to white-backed planthopper, susceptible to brown planthopper; rice quality test results: milled rice rate, head

Results from two years of regional trials: the average whole growth period was 129.8 days, the average effective panicles per mu was 204,000, the seed-setting rate was 85.3%, and the 1000-grain weight was 28.5 g; resistance identification results: susceptible to rice blast, susceptible to bacterial leaf blight, susceptible to white-backed planthopper and brown planthopper; rice quality test results: 5 indicators, including brown rice rate, milled rice rate, grain length, alkali spreading value and gel consistency, reached the Ministry-issued first-grade standard for quality edible rice. This variety has a compact plant type and medium panicle type, belongs to the panicle-grain balanced type, and has good yielding ability. It is suitable for planting in late glutinous rice areas throughout the province, but attention should be paid to the control of diseases such as rice blast.
