Summary:In the development of ratooning rice-rape planting pattern in Ganfu Plain, the anthesis bearing stage of the first season rice for ra- tooning rice cultivation usually falls in high temperature environment, so the anthesis bearing stage of ratooning rice is susceptible to cold dew wind, often resulting in low seed setting rate, high and stable yield failure. [...]the light and temperature resources are very limited for this production mode in the region, presenting seasonal tension. [...]it is very necessary and urgent to screen suitable varieties of ratooning rice which can be suitable for the ecological conditions in this region, suitable for the ratooning rice-rape planting pattern with strong regeneration ability and high and stable yield. According to the mean method, 10 panicles were used as the test samples to investigate the effective panicles, total grain number per panicle, seed setting-rate and 1 000grain weight. Comprehensive analysis showed that Heliangyou 1, Y Liangyou 6, Zhunliangyou 608 and Jingliangyouhuazhan had high yield, strong regeneration and quick emergence performances, strong lodging resistances, so they were suitable for the production and application in Ganfu Plain. [...]Heliangyou 1 and Zhunliangyou 608 showed early maturity, and were easy to achieve high yield and stable production.
