短叶13号萝卜加代技术研究

Study on Generation-adding Technology for Duanye No.13 Radish

通过低温处理萝卜干种子、萌动种子及幼苗,以期从中筛选出更适合短叶13号萝卜加代研究的材料,寻找更快、更方便的萝卜加代方法。试验结果表明,相比其他两类材料,萝卜干种子不易完成春化而开花;而在萝卜萌动种子及萝卜幼苗两类材料中,前者加代操作相对简便且低温处理定植后开花比例较高。因此,将萌动种子作为萝卜加代材料可缩短育种进程、提高育种效率。

In the paper, we treated radish dry seeds, germinated seeds and seedlings in low temperature respectively, in order to screen out suitable generation-adding material for Duanye No.13 radish and find out faster, more convenient generation-adding method for radish. The results showed that, compared with the other two materials, dry radish seeds could not flower after the cold temperature treatment. After being treated in low temperature, germinated radish seeds had higher flowering ratio and it was easier and more simple to take germinated seeds as generation-adding materials for radish. As a result, taking germinated seeds as generation-adding materials for radish could shorten the breeding process and improve the breeding efficiency of radish.
