摘要： 采用模糊数学综合评判方法,综合评价了1989年山西省高粱新杂交种区域试验材料.结果表明,6个高粱新杂交种,其中晋杂871、21A×晋粱五号、FA×8643变3个组合以亩产量、丰产素质为主,包括抗病性、抗倒性、株高在内的综合性状明显优于对照晋杂四号,达到优良或较好的评价标准,其综合指标值分别比对照增加18.29%、11.28%和7.00%.晋杂871对不同环境的适应能力强,综合性状稳定性好;旱抗六、V₄A×87382-3两个杂交种综合特性与对照相当;旱抗五劣于对照,综合指标值比对照减少5.06%.模糊综合评判方法,客观地反映了品种的综合特性,克服了仅用产量指标评价品种优劣的不足,对新品种的审定、推广利用都具有实际意义.

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.
