杂交水稻种子的纯度,直接关系到大田生产的产量。因此,杂交水稻种子纯度的高低,是大家最为关心的问题。由于杂交水稻种与其不育系、保持系的外形特征极其相似,混入杂交种中的不育系、保持系极难辨认,这就给种子室内纯度鉴定工作带来了困难。对此,我们采用种苗形态鉴定法,根据禾谷类作物种子的芽鞘因品种不同色泽有所不同的特点,用盐酸溶液处理已发芽的杂交种及其三系种子,使这
The purity of hybrid rice seeds is directly related to the yield of field production. Therefore, the purity of hybrid rice seeds is the most everyone’s concern. Due to the extremely similar appearance characteristics of hybrid rice varieties and their sterile lines and maintainer lines, it is extremely difficult to identify the CMS lines that are mixed with hybrids, which makes it difficult to identify the indoor purity of hybrids. In this regard, we use the seedling morphological identification method, according to the cereal crop seedling sheath different colors due to different characteristics, with hydrochloric acid solution of germinated hybrids and three lines of seeds, so that
