This paper had analyzed protein,lysine and tannin content and weight of thousand seeds in grains of F₁ and their parental pairs in twelve sorghum hybridized combinations.The results showed that superparental combination of protein and lysine content and weight of thousand seeds of F₁ grains were 41.6%,16.7% and 66.7% of all combinations respectively.F₁ tannin content is in among parental pair,had not superparental combination.F₁ tannin content is controlled by high value parent plant.If tannin content of any parent in parental pair is high,The F₁ tannin content will be increased.The results of analysis hybrid vigor showed that F₁ hybrid vigor is all negative value,when high parent value as control.This is showed that these quality character although had hybrid vigor in F₁ grain of some combinations.But the vigor depressionis appeared in many hybridized combinations.
Correlative analysis showed that grain tannin content between F₁ and father plant has significant positive correlation(r = 0.659).The tannin content between F₁ and mother plant;Lysine content between F₁ and father or mother plant;Protein content between F₁ and father or mother plant appeared week positive or negative correlation.The protein and lysine content of seed in parental pair plant has singnificant positive correlation.
