Pollination Mechanism and Inbreeding Depression in Niger (Guizotia abyssinica Cass.)

Abstract

Self fertilization resulted in 30 per cent of pollen sterility and 80 per cent of seed sterility in niger. Germination and survival of seedlings resulted from selfed pro- genies were very low. There was considerable reduction in yield attributes like number of branches and number of capitula which depressed the yield of self pollinated pro- genies. The inbreeding depression in vield was as high as 91 per cent. In view of the high self incompatibility, sibmating may be resorted to for developing inbred lines. By sib mating it should be possible to develop lines with desired attributes without sacrificing general vigour and production.
