全世界的稻作可分为灌溉稻、雨育低田稻、陆稻、深水稻和潮汐水田稻等5类。这些稻作种植于不同的环境,株型对于改善它们的生长发育,从而提高单产,起着极为重大的作用。例如,现代稻作品种都具有众多的分蘖,但并非所有的分蘖都可以结穗,因此通过选育消除无效分蘖,使更多的养分集中于籽粒生产,就有助于提高单产。目前,株型育种已成为稻作育种学家的当务之急。 The world’s rice can be divided into irrigated rice, rain-fed lowland rice, Upland rice, deep rice and tidal paddy rice and other five categories. These rice plants are planted in different environments and plant types play an extremely important role in improving their growth and yield and improving yields. For example, modern rice cultivars have many tillers, but not all tillers can end up, so by eliminating ineffective tillers and concentrating more nutrients on grain production, it helps to increase yields. At present, plant type breeding has become a top priority for rice breeding breeders.
