Abstract: By comprehensive appreciating method of fuzzy mathematics, comprehensive evaluation was made to new sorghum hybrids tested in various regions in 1989. The results showed among 6 new hybrids Jinza 871, 2lA×Jinliang NO.5, FA×Bian8643 were significantly superior to the control Jinza No.4 in yield per mu, yield characters, and comprehensive characters, such as disease resistance, lodging resistance and plant height. Their performance were superior or relative good by evaluation criterion. Value of their comprehensive index increased by 18.29%, 11.28%and 7.00% respectively. Also Jinza 871 had high adaptability to different environment and stable comprehensive characters. Comprehensive characters of Hankangliu and V4 A × 87382-3 were similar to the control. Hankangwu was inferior to the control and evaluated as mediocre. Compared with the control, its value of comprehensive index decreased by 5.06%.Comprehensive appreciating method of fuzzy mathematics reflected objectively comprehensive characters and overcame shortcomings of evaluation by yield index. Also it had practical meaning to evaluation and release of new varieties.

Key words: Sorghum, Hybrid, kegional test, Comprehensive evaluation
