蜜腺发达Ogura晚抽薹不结球白菜雄性不育系的鉴定

Evaluation of Late-bolting Ogura Chinese Cabbage Male Sterile Lines with Developed Nectar Gland

本试验以Ogura晚抽薹不结球白菜薹ms等为材料,通过观察和比较熊蜂对不同白菜品种访花次数和访花滞留时间的差异,选择出能吸引熊蜂访花且访花滞留时间长的Ogura薹ms植株。对选择出植株的蜜腺大小和开花结实特性进行了进一步鉴定,结果表明选出的薹ms株蜜腺发达,开花结实正常,为选育优良晚抽薹胞质不结球白菜雄性不育系奠定了基础。

By comparing of bumble bee visiting and staying time on flowers of Ogura non-heading Chinese cabbage male sterile lines,two plants were identified and selected as they attracted more bumble bee visiting.Nectar gland size,flowering,and pod set of these two plants were further determined.The results showed that the two selected plants all had developed nectar glands,flowered and set pod normally.This finding set a well foundation for breeding out elite late-bolting Ogura male sterile lines in non-heading Chinese cabbage.
