The invention provides a method for creating a male sterile line of
sorghum, 314B is taken as a female parent, 871300 is taken as male parent, a Ji 2055B is bred for years and generations; the Ji 2055B is then taken as a female parent and Ji 502B is taken as a male parent to
hybrid to obtain a generation F1, the generation F1 is subjected to self-crossing to obtain a generation F2, the
single plant of the generation F2 is subjected to self-crossing to obtain a generation F3; the generation F3 is taken as a female parent and is hybridized with a Ji-Jin long early B to obtain a generation F1, the generation F1 is subjected to self-crossing to obtain a generation F2, the
single plant of the generation F2 is subjected to continuous self-crossing, and a short-
straw narrow-leaf generation F4 isobtained after screening; the
plant of the generation F4 continues to be chosen and is subjected to self-crossing to obtain a generation F5, meanwhile, the generation F4 and a sterile line Ji 2055A are subjected to test crossing to obtain a generation F1; the chosen
plant of the generation F5 and the sterile
plant of the generation F1 are subjected to
backcrossing to obtain a generation BC1, meanwhile, the generation F5 is subjected to self-crossing to obtain a generation F6, a
backcrossing generation BC4 and a self-crossing generation F9 are obtained after continuous self-crossing and
backcrossing for multiple times, the female parent and the male parent are basically the same, a
hybrid seed is tested with a restoring line, and the plant with good plant type, super short
straw and high combining ability is named as Ji 2065A and Ji 2065B. The
hybrid plant bred from the provided super short
straw sterile line Ji 2065A is short, is high in uniformity, and is particularly suitable for mechanized production.
