Planting performance of eight new characteristic rice varieties in Xinluo District

With the design of randomized block with single factor, planting performance of eight characteristic rice varieties as post tobacco cultivars were observed. The results showed that the red rice variety "Minhongliangyou 736" got the highest yield, then the red rice variety "Minhongliangyou 136" in the next position; black rice variety "Ziliangyou 136" ranked third; and no significant differences were observed among the above three varieties; these three varieties were suitable for planting as major cultivar in Xinluo District. Yield was positively correlated with growing stages, plant height, spike length, available spike number, and 1000-grain weight, but negatively correlated with total grain number per spike, available grain number per spike, and filled grain rate. The correlation between yield and main characteristics were not significant.
