Abstract
High yielding hybrid of sorghum has combined by elite restorer with male sterile line.Elite restorer must have better characters, such as very powedul restoration, well-developed male organ, a large number of much more pollens, high combining ability, and the best agronomic and resistant traits.The genetic improvement of R-line used the screening techniques of local varieties of sorghum, crossing breeding and induces selection.Selecting types of R-line include that can restore the different sterile cytoplasm as well as high yielding grain, forage fodder yield, sweet-stalk trait, micronutrient types.The differences of inheritance of fertility restoration are make up by different CMS, some showed that a single gene or two genes was responsible for fertility restoration, some were ctntrolled by three or four genes.Restores showed genetic diversity in race and geography.关键词
