| 摘 要： | 杂交油菜在秧苗三叶期及移栽前根据植株形态特征进行苗期纯度测定 ,并将实测得“F1”代秧苗与“异型株”秧苗分类设区栽入大田。分别在越冬期和盛花期追踪调查种植纯度 ,测定其吻合率。同时 ,提出了在杂交油菜种植过程中 ,应把好育苗去杂关 ,掌握在苗床三叶期或直播田定苗时 ,根据不同组合的植株形态特征 ,采取去小苗、留大苗 ;移栽前采取栽大苗、去小苗的保纯观点。

| Abstract: | Hybrid rape is done seedling purity determination according to its morphological character at triphyllous stage and before transplanting. The F 1 generation and the heterotipe are classified and transplanted in different field plots, and their planting purity will be investigated at wintering stage and full bloom stage separately to determine the coincidence rate. Meanwhile, the dissertation also puts forward it is very important to select big seedlings to keep the purity during planting hybrid rape according to the morphological characters of different combinations. |
