A New late Indica Hybrid Rice combination

Teyou 37 is a new hybrid late indica rice combination selected by Nuclear Farmers Institute of Zhejiang University, with an average yield of 448 per mu in 2000. 8 kg, an increase of 1% over Shanyou 10. 91%. The results of the two-year zone test showed that the average whole growth period was 129. In 8 days, the average effective panicle per mu was 17. 50,000, with a seed setting rate of 83. 7%, 1000-grain weight 26. Nine grams. The results of resistance identification showed that it was moderately resistant to rice blast, susceptible to bacterial blight, susceptible to white-backed planthopper and susceptible to brown planthopper, and the results of rice quality test showed that four indexes such as milled rice rate, head rice rate, alkali elimination value and amylose content reached the first class standard of edible high quality rice issued by the Ministry. Brown rice rate, grain length, transparency and gel consistency reached the second grade standard of high quality rice. This variety has compact plant type and medium panicle type, and belongs to panicle-grain type. It has good high yield and is suitable for planting in the late glutinous rice area of the province, but attention should be paid to the control of rice blast and other diseases.
