几个辣椒核质互作雄性不育材料的育性调查

Investigation and Analysis on Fertility of Cytoplasmic Male-sterile Materials in Capsicum annuum L.

在5、7、9月,对18个辣椒核质互作雄性不育材料进行了花粉量、自然坐果率与单果种子数性状的调查。结果表明:1A、2A、4A、6A、8A、13A、17A、18A的花粉量均极少或没有,自然坐果率和单果种子数在开花坐果期一直为0,属于稳定型不育型材料;7A、12A、14A的在供试时期内可以自然坐果,但其单果种子数始终为0,也属于稳定型不育型材料;3A、5A、9A、10A、11A,可以坐果且有种子,表现出部分不育;15A、16A属于环境敏感性的不育材料,育性受环境因子的影响。

Pollen quantity,natural rate of self-cross setting and the seed number of single-fruit of 18 cytoplasmic male sterile peppers were investigated in the field.The results showed that the 1A,2A,4A,6A,8A,13A,17A and 18A with no or few pollens,of which natural rate of self-cross setting and seed number of single-fruit was 0,was stable sterility.The 7A,12A and 14A natural rate of self-cross setting in the three months have pepper setting,but its seed number of single-fruit was 0,that was stable sterility plants.The 3A,5A,9A,10A,and 11A could cross,and had seed,that was the partial sterility.15A,16A was sterile plant with environmental condition,and sterility was affected by the environment factors.
