8个特色水稻新品种在新罗区的种植表现

    Planting performance of eight new characteristic rice varieties in Xinluo District

    • 摘要: 采用单因素随机区组设计方法,探讨8个特色水稻品种作烟后稻种植的表现,结果表明:红米闽红两优736产量最高,其次为红米闽红两优136,黑米紫两优136排第三,3个品种间差异不显著,可作为新罗区红、黑米主栽品种;产量与生育期、株高、穗长、有效穗数、千粒重呈正相关,与每穗总粒数、每穗实粒数、结实率呈负相关,产量与主要性状的相关性均不显著。

       

      Abstract: 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.
