提出了水稻理想穗型的概念,分析了水稻理想穗型设计的原理,初步建立了辽宁水稻理想穗型参数:穗长<17cm,颈穗弯曲度<40°,穗颈长3~4cm,直径>2mm,大维管束数和一次枝梗数>15个/穗,一次枝梗粒数>80粒/穗,二次枝梗籽粒偏向穗轴中上部分布,穗型指数>0.5.此外,还讨论了通过理想穗型实现产量与品质在更高水平上统一起来的可能性.
The concept of ideal panicle type of rice was proposed. The principle of ideal panicle type design of rice was analyzed. The optimal panicle type parameters of rice in Liaoning were preliminarily established: panicle length <17cm, panicle curvature <40 °, panicle neck length 3 ~ 4cm, diameter > 2mm, the number of large vascular bundles and number of primary branches> 15 / spike, the number of primary branchlets> 80 / spike, the secondary branchlets tend to the upper part of the cob, panicle index> 0.5. The possibility of unifying production and quality at a higher level through the ideal panicle type.
