摘要
为油菜细胞质雄性不育系 LDX95-58A制种措施的制定提供参考，采用田间试验比较了油菜细胞质雄性不育系 LDX95-58A在不同生长时期喷施不同浓度化杀灵 WP1对其微粉的控制效果。结果表明：在油菜不育系LDX95-58A有70％主花序单个花蕾直径达0．3～0．5 mm时，喷施0．09 g/L化杀灵WP1的不育株率达95．00％，杂交种F1代的纯度达97．06％，比对照提高17．69百分点，喷药后的油菜花瓣皱缩，色淡，花丝缩短，花药无粉或败育。即化杀灵 WP1对不育系LDX95-58A微粉的控制效果较好。
The plants of LDX95-58A （a cytoplasmic male sterile line in Brassicanapus）were sprayed with different concentrations pf WP1 at different growth stages to study the control effect on the micro-pollen and to provide a reference for seed production of LDX95-58A.The sterile plant rate is up to 95%when the single flower bud with 0.3~0.5 mm diameter on main inflorescence is sprayed with 0.09g/L WP1 and F1 purity reaches 97.06%,17.69% higher than CK.The shape and color of the petal is shrunk and light,and the filament is shortened and no pollen in a anther or abortive pollen.In conclusion,WP1 has the good control effect on pollen of LDX95-58A.
