There are 16 hybrid indica varieties collected in the production of main cultivated. To identify the field and agronomy characters investigation from yield, characteristics (agronomic character, economic properties and comprehensive resistance) and rice quality were planted under the same condition of main rice varieties in Xinyang area. IIyou 838 as ck. The results showed that there were 6 species increasing of yield significantly, such as C liangyou huazhan, Gangyou 1237 and Shen liangyou 5814 which are prefecture for hybrid indica main varieties in Xinyang. 9 species such as Y liangyou 1 and Anjiang 6 were low yield. The Y liangyou series are suitable for match varieties.
