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、V_4A×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.
A comprehensive evaluation method of fuzzy mathematics was used to evaluate the regional testing materials of new sorghum hybrids in Shanxi Province in 1989. The results showed that there were 6 new sorghum hybrids including Jinza 871,21A × Jinliang 5 and FA × 8643 The combination of yield per mu, high yielding quality, including disease resistance, lodging resistance, plant height, including the comprehensive trait was significantly better than the control jasha IV, to achieve good or better evaluation criteria, the comprehensive index values were The control increased by 18.29%, 11.28% and 7.00%. Jinzha 871 adaptability to different environments, good comprehensive character stability; drought resistance six, V_4A × 87382-3 two hybrids with the comprehensive characteristics of the same; Compared with the control, the comprehensive index value was reduced by 5.06% compared with the control. The fuzzy comprehensive evaluation method objectively reflected the comprehensive characteristics of varieties and overcame the shortcomings of using only the yield index to evaluate the advantages and disadvantages of the varieties. The validation, promotion and utilization of the new varieties all had Practical significance.
