辣椒胞质雄性不育三系配套制种技术研究

Research on Seed Production Technique with Cytoplasmic Male Sterile Line and Its Maintainer Line and Restorer Line in Pepper

辣椒杂种优势非常明显,一代杂种已大规模应用于生产,取得了巨大的经济效益和社会效益。但辣椒杂交种的生产主要靠人工去雄、授粉,不仅生产成本高,而且种子纯度难以保证。利用雄性不育系制种是解决这一难题的有效途径。通过对辣椒雄性不育系、保持系、恢复系的繁育技术及辣椒胞质雄性不育杂交制种技术的研究,在苗床土壤消毒、种子处理、田间管理及杂交授粉等方面进行了创新与改进,保证了种子质量,降低了生产成本,提高了辣椒一代杂种种子的市场竞争力。

The heterosis of pepper were very obvious,and the hybrids were large-scalely applied to commercial production followed tremendous economic and social beneficial results.However,the output cost of pepper＇s hybrid were higher,but also the prurity could not be ensured because of manual emasculation and pollination.But these difficulties could be solved using male sterile line.In this experiment,not only the propagation of pepper cytoplasmic male strerile line,maintainer line and restorer line,but also the hybrid seed production technique were studied.Some other fields were also innovated and improved,such as soil disinfection on seedbed,seed treatment,field management,hybriding pollination,and so on.These series of measures could ensure seeds＇ quality,reduce the output costs,and improve the competitive ability of hybrid seeds in market.
